Deloplen is a redirect virus that pushes ads and other commercial content on Google Chrome and other browsers
Deloplen is an unsafe domain that users can encounter during their web browsing sessions on Google Chrome, Safari, Mozilla Firefox, Internet Explorer, or another browser.
While some people might be redirected to it from other malicious sites, persistent and involuntarily visits most likely indicate adware infection.
Ad-supported software, generally classified as "not a virus," sometimes can possess multiple rogue techniques malware uses for its infection, persistence, and detection. Luckily, researchers manage to share new light on adware, claiming it can be just as dangerous as viruses. Therefore, redirects to Deloplen.com or similar domains should not be overlooked as just a nuisance.
Deloplen adware can modify web browser settings, redirect to suspicious scam or phishing domains, display deals, offers, pop-ups, flashing windows, etc. However, users rarely understand where the intrusive content is coming from. This is because potentially unwanted programs are usually included in software bundles, and careless installation of freeware results in infiltration of optional components, i.e., adware, browser hijackers, or even malicious software.
Domains like Deloplen are created purely to generate advertisement revenue. Each time users click on a link, install an app or make a purchase, adware authors receive money. Therefore, it is in PUP developers' best interest to present as much commercial content as possible.
Unfortunately, the advertisement network is not always secure, as ad space can be bought by cybercriminals who can incorporate malicious links inside. That is especially true for websites that are less monitored, such as porn, gambling or torrent sites. Therefore, redirects from Deloplen.com might lead to such domains, where malicious links can result in malware infection.
That being said, as long as you do not click on any promotional links or the content you got redirected to, you should avoid all the negative consequences. Nevertheless, to remove Deloplen redirection tendencies, you will have to terminate the adware application that is installed on your device, or the security level will not be sufficient.
Additionally, if you suffer from Deloplen virus redirects, it might be that your browsing behavior is being monitored. Usually, the following data is collected:
While it is considered to be standard practice to gather such-like information, there is no need to expose it to unknown parties that are linked to Deloplen.com. Thus, clean your browser and the computer from this unwanted activity - you can do it either manually or automatically.

Beware of adware when installing new apps
Software bundling is a well-known tactic that is being used to distribute potentially unwanted programs.
Users are often keen on downloading and installing software from sites like Download.com, File Hippo, Softpedia, Softonic, etc., but not many are aware that most of the installations might lead to PUPs. It is simply how it is - third party sites rely on ads and bundled software to monetize. Therefore, it is vital to pay attention when establishing media players, PDF converters, driver downloaders, and similar tools.
Thus, be attentive when installing new software:
Another way to infect your machine by adware is after being misled by an attractive ad on the internet or online scams. The former might convince you with the attractive functionality of the app, while the latter will inform you about the alleged virus infections and possible data theft. In fact, already present adware often leads to phishing sites, so installing more bloatware becomes a question of time.
- Do not rush the installation - pay attention to every detail;
- Look out for misleading buttons, grayed out buttons, pre-ticked boxes, etc.;
- Decline all the offers or deals on the way;
- Check out Privacy Policy, Terms of Service and other provided documents (do not install anything that does not include these);
- Choose Advanced or Custom installation settings instead of Recommended/Quick ones and remove all optional components from the final installation list.

How to remove Deloplen.com ads
How to remove the Deloplen.com extension
Do the browser steps in every browser and profile on the PC, then check Windows for the program that installed the extension.
Step 1: Remove extensions you did not add
In Chrome open
chrome://extensions, in Edgeedge://extensions, and in Firefox the menu > Extensions and themes.Remove every extension you do not remember adding, especially search, new tab, coupon, PDF, weather or video downloader add-ons. Check every browser and every profile, because each keeps its own list.
If an extension has no Remove button or comes back, a browser policy holds it (see "Managed by your organization" in the procedure below). The pages are the same on Windows 11 and Windows 10.

Chrome on Windows 11: More > Extensions > Manage extensions. Full procedure with screenshots: Remove a browser extension
Step 2: Uninstall programs you did not mean to install
Deloplen.com rarely comes alone: it is usually installed by, or together with, a free program. In Windows 11 open Settings > Apps > Installed apps, in Windows 10 Settings > Apps > Apps & features, and sort by install date.
Uninstall every entry from the day the trouble began that you did not install on purpose, for example a download manager, a converter or a browser you never chose.
Keep drivers and entries from Microsoft, Intel, AMD, NVIDIA or your PC's maker unless you are sure.

Step 3: Reset the browser
A reset removes what the steps above could miss:
- changed start pages
- site permissions
- hidden settings
In Chrome open Settings > Reset settings > Restore settings to their original defaults; in Edge Settings > Reset settings; in Firefox Help > More troubleshooting information > Refresh Firefox.
Tip: Bookmarks and saved passwords stay, while extensions are turned off and the search engine and start page return to the defaults.
Reset every browser on the PC, including Edge, which Windows 11 and Windows 10 always have.

Chrome on Windows 11: Settings > Reset settings. Full procedure with screenshots: Reset a browser and fix a hijacked search engine
Step 4: Scan the PC, then run the offline scan
A scan finds the parts of Deloplen.com that the manual steps cannot see. In Windows Security > Virus & threat protection > Scan options, start a Full scan and quarantine what it reports.
Follow it with Microsoft Defender Antivirus (offline scan) > Scan now, which restarts the PC and checks the disk while Windows and the malware are not running.
It takes about 15 minutes and works the same in Windows 11 and Windows 10. If either scan finds something, run the full scan again after removal until it comes back clean.

Windows 11: Windows Security > Virus & threat protection > Scan options. Full procedure with screenshots: Run a Microsoft Defender Offline scan

Protect your privacy - employ a VPN
There are several ways how to make your online time more private - you can access an incognito tab.
However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise.
Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and VPN will let you browse the Internet without a feeling of being spied or targeted by criminals.
No backups? No problem. Use a data recovery tool
If you wonder how data loss can occur, you should not look any further for answers - human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence.
In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.
If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. is one of the leading file recovery solutions you can find on the market - it is likely to restore even lost emails or data located on an external device.

Stop Deloplen.com redirects by removing adware from your device
Deloplen removal might be either a fast process or in some cases, quite lengthy one - it highly depends on your system configuration, experience with computers, and the amount of already installed PUPs or even malware.
First, you could go into the list of all installed programs, and look for suspicious entries there (note that you will not find Deloplen.com on the list - it is simply not how it works). If you find any, terminate them by uninstalling the app.
On the other hand, if you are unsure if your device is infected with malware, or you are not that good computers in general, you should rely on anti-malware software that would remove Deloplen virus and all other unwanted programs automatically.
Questions about Deloplen.com ads
How do I stop deloplen.com from opening?
Find and remove whatever opens it. Start with the browser's extensions page and remove anything you do not remember adding. Next, open the notification settings and take away permission from sites you do not recognise.
Then check Settings > Apps > Installed apps for programs added around the day the redirects began, and uninstall those. Restart the browser and test a few links after each step.
If deloplen.com still appears, reset the browser, which restores the default search engine, start page and permissions without deleting bookmarks or saved passwords. Redirects that survive a reset in every browser point to a program in Windows, and a full scan is the next step.
Should I worry about redirects to deloplen.com?
Worry less about deloplen.com itself and more about what keeps sending you there. A single redirect from a free streaming or download site is normal and harmless once the tab is closed.
Repeated redirects on sites that used to work fine mean something in the browser or in Windows changed, often an extension or program installed alongside other software. It may also collect the pages you visit. Remove the cause with the steps in this guide, and do not act on anything the redirected pages ask:
- no Allow clicks
- no downloads
- no calls
If you already did one of those, the matching section of this guide explains what to do next.
Why does Deloplen.com show me ads?
Because that is its whole purpose. Deloplen.com is an adware extension, and its operators are paid for every ad it displays and every click it gets. In this case the ads take the form of redirects through ad pages.
They are chosen by ad networks that accept almost any advertiser, which is why so many look like warnings or prizes. The ads are not a sign that your PC is broken or infected with something worse; they are a sign that something on it, or in the browser, has permission to advertise. Removing that permission or program stops them.
Do I have to clean every browser?
Yes, if you use more than one. We saw Deloplen.com in Chrome, Edge and Firefox, and each browser keeps its own extensions, notification permissions and settings. Chrome and Edge share the same extension format, so one installer can add the same adware to both, while Firefox has its own add-ons.
Check every browser on the PC, including ones you rarely open. If you sync a browser with an account, clean it while signed in, so that the removal reaches your other computers rather than the adware returning from them.
How do I know the ads come from Deloplen.com?
Look for redirects to deloplen.com. That is the trace Deloplen.com leaves, and it shows up as redirects through ad pages. Ads that appear on every site, including ones that never carried ads before, point to something on your PC or in the browser rather than to the sites themselves.
A quick test is a private window, where extensions are off by default: if the ads disappear there, an extension is responsible. If they appear even with the browser closed, the source is a notification permission or a program in Windows.
I clicked on one of the ads. Am I infected?
Probably not. Clicking an ad usually only opens a page, and a page cannot install programs on an up-to-date Windows PC without your help.
You are at risk only if you then downloaded and ran a file, allowed notifications, entered card or login details, or called a phone number shown on the page. Delete any download and run a full and offline scan.
Change passwords you typed, from a clean device. Call your bank if you gave card details. If you called a number or allowed remote access, see the next question.
Why didn't my antivirus catch Deloplen.com?
Many security products do not block adware or notification sites by default, because users often agreed to them, even through a misleading prompt. Notification spam installs nothing at all, so there is no file to detect.
In Windows 11 you can make Microsoft Defender block potentially unwanted apps: open Windows Security > App & browser control > Reputation-based protection settings and turn on Potentially unwanted app blocking. If notifications caused the pop-ups, no scanner will report them; the fix is in the browser's site settings.
An ad showed a phone number and I called it. What now?
The number belongs to scammers, not to Microsoft or an antivirus company. If you only talked, hang up and do not call back. If you let them connect to the PC, disconnect it from the internet, uninstall the remote access program they used, such as AnyDesk, TeamViewer, ScreenConnect or UltraViewer, and run a full and offline scan.
If you paid or gave bank details, call your bank at once on the number printed on your card. Change any passwords you typed while they were connected, and report the call.
Does adware steal passwords?
Ordinary adware is built to show ads, not to steal logins, and most of it never touches saved passwords. The line is blurry, though. Extensions that can read every page could capture what you type, and adware ads sometimes lead to phishing pages that ask for passwords directly.
If you entered credentials on a page reached through an ad, change that password from a clean device and turn on two-step verification. Otherwise, removing adware extension and clearing cookies is usually enough.
Will Fortect remove Deloplen.com?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For Deloplen.com, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
