Tsyndicate.com: what it is and how to stop its ads and pop-ups
Tsyndicate.com is the web address of an advertising service: other websites load its ads, and in 2020 a page on the address itself asked visitors to click Allow for notifications. On our October 2026 check its front page answered with nothing, and opening the address installs nothing, so the fix is to take back any notification permission and remove anything you installed from an ad.
Facts checked October 7, 2026. Removal steps tested on Windows 11 (26H2) and checked against Microsoft's and the browser makers' current documentation.

Facts checked on 6 October 2026 against our own test of tsyndicate.com in desktop Chromium from Lithuania, our own plain requests to tsyndicate.com and cdn.tsyndicate.com, the text of the ad script file read without running it, and the registry's RDAP record for the domain.
What Tsyndicate.com is and why you see it
Tsyndicate.com is a web address that serves ads, not a program. Our 2020 report called it a virus and a "push notifications-causing program". What we can show today is an address whose script other websites load to display ads, and, in 2020, a page on the address that asked for notification permission. Opening the address installs nothing on your PC.
- 1
A page you visit loads its ads
Websites that sell ad space add a line that loads files from cdn.tsyndicate.com. We read one of them, /sdk/v1/n.js (64 KB, dated 22 September 2026). By its own text it draws ad thumbnails and video ads, marks them "AdsBy" and opens a clicked ad in a new tab. We did not run it, so we cannot say which ads it shows to whom.
- 2
Your blocker names the address
In April 2025 a person who wrote that the domain was theirs asked Malwarebytes why its browser extension showed "Website blocked due to ads". The reply was that Browser Guard blocks all ads and ad servers (Malwarebytes Forums). A blocker alert with this name means an ad request was stopped, not that something was found on your PC.
- 3
A page on the address can ask for Allow
The pictures in our 2020 report show a page on tsyndicate.com with a fake video player that says "Click Allow to play or download" and a notification prompt over it. We did not see such a page in 2026, and the address cannot be told apart from the ads that link to it.
- 4
One click on Allow is remembered
If a notification prompt appears and you click Allow, the browser keeps that permission for the site address until you remove it (Chrome Help). Closing the tab does not take it back.
- 5
Ads then arrive as notifications
The site's server sends messages through the browser's push service, and they show in the corner of the screen even when no page from the site is open. Chrome and Edge keep running in the background by default, so this works after the last window is closed; Firefox shows them only while it is open (Mozilla Support).
- Address
- tsyndicate.com; ad files come from cdn.tsyndicate.com. The name www.tsyndicate.com does not resolve at all
- Registration
- Created 8 March 2017 at the registrar Danesco Trading Ltd., last changed 30 September 2026, paid until 28 May 2030 (registry RDAP record)
- Our report
- First published 28 May 2020, so the address is older than our report and still registered
- What the front page answers
- HTTP status 204 (No Content): headers and no page, with a noindex header
- What it needs from you
- Clicks on an ad and, if a prompt appears, one click on Allow; no download is needed for the notifications
What tsyndicate means, and what tsyndicate.com document in a log means
Tsyndicate is the name of an ad serving web address, not a program or a virus.
A vendor list for consent tools describes tsyndicate.com as a marketing domain run by Traffic Stars, a pop and push advertising network. That network serves ads, builds audiences and measures conversions. When you see the word tsyndicate, it means an ad from that network was loaded or blocked.
We found no reliable source that explains the search tsyndicate com document, so this is our reading. Ad blockers and browser developer tools label each request by type. The type document means a whole page was opened in a tab, usually after a click, as in a pop-under or a new tab. The types script and iframe mean an ad loaded inside another site.
So a log line that shows tsyndicate.com with the type document most likely means a page of the ad network opened as its own tab. It does not mean a file called document was saved on your computer. To check yourself, open the blocker's logger or the browser's developer tools, look at the type and the page that started the request, and close that site.
Tsyndicate com document and tsyndicate meaning, answered in short
Tsyndicate.com document in a browser log, a blocker report or a network tool means the browser tried to open tsyndicate.com as a whole page, not as a small ad file inside another page.
Browsers label such a request with the destination document, as MDN describes for the Sec-Fetch-Dest header. In practice it points to a new tab or a redirect that an ad on another site started, often right after a click.
A document entry on its own does not mean anything was installed on your PC. It records that a page was requested. If your blocker stopped it, nothing from that page loaded. If it loaded and asked you to click Allow, check the notification list of your browser and remove tsyndicate.com from it, as the steps in this guide show.
Tsyndicate has no official meaning that we could find. A consent vendor profile links the address to the Traffic Stars ad network. Our reading is that the name stands for traffic syndicate, a term for a network that sells ad traffic from many sites. Treat this as our reading, not a fact confirmed by the company.

Is Tsyndicate.com dangerous?
Our test on 6 October 2026
We opened tsyndicate.com the way a visitor does: a clean desktop Chromium browser in Lithuania, one visit, and then read the answers with plain requests. The browser showed no page, because the address sent none.
Tsyndicate.com · desktop Chromium · Lithuania · 6 October 2026
- PageThe browser stopped with ERR_ABORTED. A plain request showed why: the front page answers with status 204 (No Content), so there is nothing to display. It also sends a noindex header.
- RedirectNone on this one visit; the address stayed the same and no other domain was contacted.
- Notification requestNone on this one visit; there was no page to ask. The ad script we read has no call that asks for notification permission (we searched its text for requestPermission, Notification, serviceWorker and pushManager: no match).
- Pop-upsNone opened on this one visit.
- Service workerNone registered in the browser, and /sw.js on the address answers 404.
- Hostscdn.tsyndicate.com answers and serves the ad script. www.tsyndicate.com does not resolve, the same error shown in our 2020 picture, so "this site can't be reached" for the www name says nothing about the address without it.
- Device detailsThe front page asks Chrome and Edge, in an Accept-CH header, to send the browser's brand and version, platform and its version, device model, processor architecture and bitness on later requests (see the data section below).
- Not testedThe /api/v1/direct/ links that ads use (each ad has its own link), other countries, phones, other referrers, a second visit, a click and visits through an ad. Ads are chosen per visitor, so one empty front page tells us nothing about what an ad on another site shows you.
- Old permissionA notification permission allowed in 2020 or later stays in the browser under this address, whatever the page answers today. If notifications under this name keep arriving, they come from that permission.
Low risk on this one visit The address did nothing visible when we looked: an empty answer, no prompt, no pop-up. That is one visit from one place and does not clear the name, because the ads and links it serves are different for different visitors and its page asked for notifications in 2020.
What the 2020 report showed, and what changed
8 March 2017
The domain is registered
The registry record gives this date. Our report came three years later, and the same registration is still in force.
Around 2020
A page on the address asks for Allow
The first picture in our 2020 report shows a page on a tsyndicate.com address under /api/v1/direct/. A black player marked 0:00 / 3:15 reads "Click Allow to play or download", and a box above it says "We'd like to send you notifications for the latest news and updates" with NO THANKS and ALLOW buttons and a FREE GIFT image. No video plays: the player is a picture, and Allow gives the site notification permission. The report also said the ads on the address changed all the time and included fake online shops, installers of download managers and converters, and sponsored videos.
From our 2020 report: the fake player and the Allow prompt. It is not a capture from our 2026 test. Around 2020
A scan site and a blocked address
The second picture shows a VirusTotal page for tsyndicate.com with 0 of 71 engines flagging it and two community comments: one says the website is spreading malware, the other (in Russian) complains about blockers. Behind it is Chrome's "This site can't be reached" for www.tsyndicate.com with ERR_NAME_NOT_RESOLVED. A clean scan result and an unreachable www name do not show what the ads linked to; both are still true for the www name today.
From our 2020 report: the scan result and the error for the www name. It is not a capture from our 2026 test. 28 May 2020
Our report is published
It called the address a suspicious website that redirects visitors and promotes malware and blamed adware on the PC for it. The report was not changed after that date.
29 April 2025
A blocker names the address
A person who wrote that the domain was theirs asked why Malwarebytes' browser extension blocked it as "Website blocked due to ads"; the answer was that the extension blocks all ads and ad servers, and the thread was locked.
22 September 2026
The ad script is updated
The script file we read carries this date in its first line and in its server header, so the ad service was being worked on shortly before our check.
30 September 2026
The registration record changes
The registry shows the record last changed on this date, with the domain paid until 28 May 2030.
6 October 2026
Our new check: an empty answer
One visit showed no page, prompt, redirect or pop-up.
What the prompts and alerts say, and how to read them
None of these lines tells you that your PC is infected. A web page cannot scan your PC, and a blocker alert only says that a request to an ad server was stopped.
| What you see | What it pretends to be | What it really is |
|---|---|---|
| Click "Allow" to play or download | A video player or a download button | A picture of a player. Allow gives the site notification permission; no video follows |
| We'd like to send you notifications for the latest news and updates | A routine permission box | The same request. The "news and updates" that follow are ads |
| tsyndicate.com wants to: Show notifications (Allow / Block) | A question about one site | The browser's own prompt, the kind our 2020 report quoted. Allow keeps the permission until you remove it |
| Website blocked due to ads | A virus warning | Your blocker stopped a request to an ad server; the page you were on tried to load an ad |
| This site can't be reached (ERR_NAME_NOT_RESOLVED) | Proof the site is gone | True for www.tsyndicate.com only. The name without www answers, and cdn.tsyndicate.com serves the ad script |
| Fake shop, download manager or converter page | A useful offer | An ad destination. Our 2020 report named these; we did not see them in 2026 |
Alert, notifications, pop-ups or redirects: which are you seeing?
Our 2020 report said that adware on the PC causes the redirects to this address. A page you visit can load its ads, and a browser can keep a permission, without any adware. The causes look alike and have different fixes.
| What you see | Most likely cause | What to do |
|---|---|---|
| Your blocker or security tool says tsyndicate.com was blocked | The page you were on loads ads from it and the blocker stopped them | Nothing to remove. The alert is the blocker working; leave the page if the ads bother you |
| Ads in the corner of the screen at random times, with no page from this site open | A notification permission allowed earlier | Block the site in the browser's notification list (steps in the removal plan above) |
| New tabs open after you click a video, a download button or an ad | Ad links on that page open in a new tab, as the ad script does with a clicked ad | Close the tab and do not click on; nothing needs removing from the PC |
| Many unrelated sites show the same ads, or the start page, the search engine or the extensions list changed without you | An unwanted browser extension, or a program that came with free software (adware) | Check the extensions and the list of installed apps, then reset the browser (sections below) |
| Other domain names appear in the address bar each time | A chain of ad networks passes you on; one of them is this address, and you cannot tell from the name which one caused a pop-up | Note the domain in the notification itself and block that sender, not only this one |
What the ad requests tell the ad network
Our 2020 report said that ads of this kind collect the IP address, location, most viewed pages and searched items. We can show part of that, and we cannot show the rest.
Device details the front page asks Chrome and Edge to send (Accept-CH header, read 6 October 2026)
- Browser brand and version
- Operating system (platform)
- Operating system version
- Device model
- Processor architecture
- Bitness (32 or 64)
- Windows-on-64-bit flag
- Full browser version list
- Mobile or desktop
The header asks the browser to include these on later requests to the address. Chrome and Edge support client hints; Firefox and Safari do not (MDN).
- In the ad script
- Text for cookies and browser storage, a call to fetch data, and addresses for ad statistics and ad reports on tsyndicate.com (we did not run the script, so we do not know what it stores or sends)
- In every request
- Any server you load a file from sees your IP address; the address is how it answers you
- Not shown
- That the service reads your search terms, your files or your passwords. We found no sign of it, and a page cannot read them without you typing them in
Tracking for ads is a privacy matter, and you can limit it with a blocker or by turning off third-party cookies. It is not identity theft: that follows from what you type on a page or from a file you run (FTC).
The real risks, from most to least serious
The notification permission installs nothing. These are the ways the ads and pages that follow it can hurt you.
- High
Running a file or extension an ad offers
Fake players, download managers, converters and "cleaners" are how adware and trojans get onto a PC. Our 2020 report named such installers among the ads on this address.
- Medium
Fake shops and forms behind an ad
A page that asks for a card number, a phone number or a login to "claim" something sends what you type to whoever runs it.
- Medium
More ads and pages from the same chain
A click leads to more shady pages, and each can ask for notification permission or offer another download. This is how one visit turns into several.
- Low
The permission alone
It lets the site show notifications and nothing else. It is a nuisance, and it stays until you remove it.
How Tsyndicate.com got into your browser
Our 2020 report named software bundling as the main way unwanted programs arrive. It is a real route for adware, and we have no evidence of how any given reader met these ads.
| Where it starts | What you see | What to do |
|---|---|---|
| A free program's installer | Express or Recommended setup installs extra programs and extensions that are ticked by default | Choose Custom or Advanced and untick everything you did not come for |
| Torrent sites, cracks and "free" copies of paid programs | An installer wrapped around extras, or a file that is not what its name says | Get the program from its maker's site or the Microsoft Store |
| An ad or a notification that offers a player, an update or a cleaner | A download that starts after one click | Do not open the file; delete it from Downloads |
| A browser extension offered on a page | A changed start page, search engine or new tabs | Remove it in the extensions list and reset the browser |
How to remove Tsyndicate.com
How to stop Tsyndicate.com notifications
Do this in every browser you use, and in every profile inside it: each keeps its own list of sites allowed to send notifications.
Nothing has to be uninstalled for the notifications themselves.
Which browser shows the ads?
Step 1: Remove tsyndicate.com from Chrome's notification list
Open More (the three dots) > Settings > Privacy and security > Site settings > Notifications, or paste
chrome://settings/content/notificationsinto the address bar.Under Allowed to send notifications, open the menu next to
tsyndicate.comand choose Remove or Block, and do the same for any other address you do not recognise.Next to Not allowed to send notifications, click Add and enter tsyndicate.com, so the site cannot ask again. The menus are the same in Chrome on Windows 11 and Windows 10, and each Chrome profile keeps its own list.
Chrome on Windows 11: Settings > Privacy and security > Site settings > Notifications. Full procedure with screenshots: Stop website notifications and pop-ups
Still there? More for Google Chrome
On an Android phone
In Chrome tap the three-dot menu > Settings > Site settings > Notifications. Tap each unknown site under Allowed and pick Reset permissions, or turn notifications off for all sites. Then look in Settings > Apps for apps you did not install.
Remove extensions you do not recognise
Type
chrome://extensionsin the address bar and press Remove on any extension you did not add, such as a video downloader or a "search" helper.Full procedure with screenshots: Remove a browser extension
Reset Chrome
Go to Settings > Reset settings > Restore settings to their original defaults > Reset settings. The start page and search engine return to default and extensions are switched off; bookmarks and passwords stay. To stop alerts after Chrome is closed, also turn off Settings > System > Continue running background apps when Google Chrome is closed.
Full procedure with screenshots: Reset a browser and fix a hijacked search engine
Step 1: Remove tsyndicate.com from Edge's notification list
Edge stores its own permission list, separate from Chrome's, and it is often the browser behind these pop-ups on Windows 11 and Windows 10.
Go to Settings > Privacy, search, and services > Site permissions > All permissions > Notifications, or paste
edge://settings/content/notifications. Removetsyndicate.comfrom Allowed, then add it under Not allowed to send notifications. Notifications that show the Edge logo come from this list.
Edge on Windows 11: Site permissions > All permissions > Notifications. Full procedure with screenshots: Stop website notifications and pop-ups
Still there? More for Microsoft Edge
Remove extensions you do not recognise
Type
edge://extensionsin the address bar and press Remove under any extension you did not add.Full procedure with screenshots: Remove a browser extension
Reset Edge
Go to Settings > Reset settings > Restore settings to their default values > Reset. Extensions are switched off and the start page returns to default; favourites, history and passwords stay. To stop alerts after Edge is closed, turn off Settings > System and performance > Continue running background extensions and apps when Microsoft Edge is closed.
Full procedure with screenshots: Reset a browser and fix a hijacked search engine
Step 1: Remove tsyndicate.com from Firefox's notification permissions
In Firefox the permission sits in Settings > Permissions and data > Notifications (in older versions Privacy & Security > Notifications > Settings). Select
tsyndicate.comin the list, click Remove Website, and confirm with Save Changes.Firefox only shows these notifications while it is open, so if they stopped after closing Firefox, this is the browser to clean. The steps are the same on Windows 11 and Windows 10.
Firefox on Windows 11: the Notification Permissions window. Full procedure with screenshots: Stop website notifications and pop-ups
Still there? More for Mozilla Firefox
Remove add-ons you do not recognise
Type
about:addonsin the address bar, open Extensions and choose Remove from the three-dot menu of any add-on you did not install.Full procedure with screenshots: Remove a browser extension
Clear cookies and site data
Go to Settings > Privacy & Security > Cookies and Site Data > Clear Data, tick both boxes and press Clear.
Refresh Firefox

Full procedure with screenshots: Reset a browser and fix a hijacked search engine
Take back the notification permission
In Safari 18 or later on macOS open Safari > Settings > Websites > Notifications, select
tsyndicate.comor any site you do not know, and choose Deny or Remove. Untick Allow websites to ask for permission to send notifications so no site can ask again.Remove extensions you do not recognise
Open Safari > Settings > Extensions, select any you did not install and press Uninstall.
Clear the site data
Open Safari > Settings > Privacy > Manage Website Data and remove the site, or use History > Clear History > all history.
Check the Mac for apps from the ads
Pages like this push fake players and "cleaners" to Mac users. In Finder > Applications move unknown apps to the Bin, and remove unknown entries in System Settings > General > Login Items & Extensions. Then use Go > Go to Folder to look in
/Library/LaunchAgents,~/Library/LaunchAgents,/Library/LaunchDaemonsand/Library/Application Supportfor items with the same names, and empty the Bin.
Then, whichever browser you use
Step 2: Scan the PC if you downloaded anything from the ads
Most people who only saw the notifications can skip this step. If a notification or the page it opened made you download or run a file, delete the file and run a full scan, then a Microsoft Defender Offline scan.
In Windows 11 and Windows 10 open Windows Security > Virus & threat protection > Scan options, select Microsoft Defender Antivirus (offline scan) and click Scan now. The PC restarts and the scan takes about 15 minutes, so save your work first.
Windows 11: Windows Security > Virus & threat protection > Scan options. Full procedure with screenshots: Run a Microsoft Defender Offline scan
After removal: keep the ads from coming back
If you ran a file or the pop-ups keep coming
Browser steps cover notifications. If pop-ups or redirects continue, or you ran a file that an ad offered, add these three. We give no registry steps: a notification permission does not touch the registry, and we have not confirmed a registry entry that this address creates.
- 1
Remove unknown programs
In Windows 11 open Settings > Apps > Installed apps (Apps & features in Windows 10), sort by install date and uninstall what appeared on the day of the click (Uninstall a program or app in Windows On uGetFix).
- 2
Scan twice
Run a Microsoft Defender Full scan, then the Microsoft Defender Antivirus (offline scan), which runs before Windows starts. On a Mac, look through Applications and Login Items as in the Safari steps.
- 3
Reset the browser
Changed start pages, search engines and extensions are undone by the reset for your browser above.

How to avoid fake players, bundled installers and notification traps
Do
- Close a page that asks you to click Allow to play or download a video; real players do not need notification permission.
- Switch notification prompts off: Chrome Settings > Privacy and security > Site settings > Notifications > Don't allow sites to send notifications.
- Install software from the maker's site or the Microsoft Store, and pick Custom or Advanced setup to untick bundled extras, even on torrent or free-download sites.
- Leave Microsoft Defender SmartScreen or Chrome's Enhanced protection on.
- Keep a recent backup of your files.
Don't
- Click Allow unless you want that site's notifications.
- Pick Express or Recommended setup in a free program's installer.
- Open a file that an ad or notification calls an update, player or cleaner.
Questions about Tsyndicate.com
What is Tsyndicate.com?
Tsyndicate.com is the web address of an advertising service, not a program. Other websites load ad files from its cdn.tsyndicate.com host, and a script we read on 6 October 2026 draws ad thumbnails and video ads and opens a clicked ad in a new tab.
Our 2020 report also showed a page on the address with a fake video player that asked visitors to click Allow for notifications. The domain was registered on 8 March 2017 and is paid until 28 May 2030.
When we opened the front page it answered with no content, so there was nothing to see. One visit does not clear the name, because ads differ by visitor.
Is Tsyndicate.com a virus or malware?
No, Tsyndicate.com is not a virus: it is a website address, and a website cannot install a program just because you opened it. Our 2020 report called it a virus and a malware promoter, but the evidence we have today shows an ad service.
The risk lies in what the ads and pages ask of you: a click on Allow gives the site permission to send notifications, and a file offered as a player, update or cleaner is how real malware arrives.
A VirusTotal result in our 2020 pictures showed 0 of 71 engines flagging the address, which says the address is not itself a malware file, not that every ad it serves is safe.
Why is my blocker or antivirus blocking Tsyndicate.com?
Your blocker is stopping a request to an ad server. A person who wrote that the domain was theirs asked Malwarebytes in April 2025 why its browser extension showed "Website blocked due to ads", and the reply said Browser Guard blocks all ads and ad servers.
So the alert means that a page you opened tried to load an ad from this address, not that a file was found on your PC. You do not need to remove anything. If the alerts bother you, leave the page that triggers them, or check that you did not allow notifications from it.
How do I stop Tsyndicate.com notifications and pop-ups?
Take the permission back in your browser. In Chrome, open Settings > Privacy and security > Site settings > Notifications, find tsyndicate.com or any address you do not recognise under the allowed sites, and choose Block.
In Edge the list is under Settings > Cookies and site permissions > Notifications. In Firefox, open Settings > Privacy & Security > Permissions > Notifications > Settings, set the site to Block and save.
In Safari on a Mac, open Safari > Settings > Websites > Notifications and set it to Deny. On Android, use Chrome's Site settings > Notifications list. If notifications show another name, block that sender too.
Why does Tsyndicate.com keep opening new tabs or redirecting me?
A page you visited loads ads, and ad links open in new tabs. The ad script we read opens a clicked ad with a new-tab target, so a click on a video, a download button or a banner can open a page you did not choose, and that page may pass you on through other ad networks.
This does not need adware on your PC. If the same pages open on many unrelated sites, or your start page, search engine or extensions changed, then check the extensions list and the installed apps, and reset the browser. If it happens on one site only, stop using that site.
Why does Tsyndicate.com show a blank page or an error when I open it?
Because the address is made for ads, not for visitors. When we opened tsyndicate.com on 6 October 2026 it answered with status 204, which means no content, so a browser has nothing to show and Chromium reported ERR_ABORTED.
The name www.tsyndicate.com does not resolve at all, which is the "This site can't be reached" error in our 2020 picture. The files that matter sit on cdn.tsyndicate.com and are loaded by other websites. An empty front page tells you nothing about whether the ads it serves are safe: those links are made per visit.
I clicked Allow on Tsyndicate.com. What should I do now?
Remove the permission first, then check whether anything else happened. Block the site in the browser's notification list. If you only clicked Allow, nothing is installed and the browser steps are enough.
If you ran a downloaded file, uninstall programs you do not know by install date, run a Microsoft Defender full scan and an offline scan, and reset the browser.
If you typed a password or card details on a page that opened from an ad, change the password and call your bank about the card. Do this even though the front page is empty today, because the permission stays.
Do I need antivirus software or a registry cleaner to remove Tsyndicate.com?
No, not for the notifications. The permission is a browser setting and is removed in the browser, with no extra software.
A scan is worth running if pop-ups or redirects continue, if your browser settings changed, or if you ran a file from an ad. Windows 11 and 10 include Microsoft Defender, which can run a full scan and an offline scan.
We give no registry steps and do not suggest registry or optimisation tools: a notification permission does not change the registry, and we have not confirmed a registry entry that this address creates. We do not claim that any product removes this address, since it is a website.
How do I avoid ads and installers like the ones on Tsyndicate.com?
Install programs only from their makers' sites or the Microsoft Store, and in any installer pick Custom or Advanced setup and untick extras instead of Express or Recommended. That also holds on torrent and free-download sites, where bundled extras are common.
Never click Allow on a page that gives a reason other than wanting its notifications, such as playing a video. You can turn the requests off: in Chrome, Settings > Privacy and security > Site settings > Notifications > Don't allow sites to send notifications.
A content blocker also stops ad requests like the one your tool reported, and Microsoft Defender SmartScreen or Chrome's Enhanced protection add a check on downloads.
Will Fortect remove Tsyndicate.com?
No program removes Tsyndicate.com itself, because there is nothing on the PC to remove: the notifications come through a permission saved in the browser, and only the browser's settings take it away, as the steps above show.
What Fortect can do is check the rest of Windows. Its free scan looks for malware, unwanted programs and damaged system files, which is useful if you clicked the ads, downloaded something from the pages they opened, or are not sure what else changed on the PC.
If the scan finds nothing and the notifications stopped after you removed the permission, this problem is solved. Use Microsoft Defender as a second opinion whenever you have downloaded files from pages like these.
