Is Bot-checker.com ads dangerous?
From our report of Sep 2020 · not reviewed since
Bot-checker.com is the program that triggers issues with the device because it exposes the user to shady advertisements
Bot-checker.com - adware-type intruder that claims to show valuable and useful material, but it only tricks people into allowing push notifications.
The site itself delivers nothing besides the pop-up with claims about notifications and agreement form that determines if you want to see notifications and additional content or not. Unfortunately, those pop-ups show up all the time and get extremely intrusive, so people may click on the advertisements and allow those push notifications without even noticing.
Pop-ups that this site triggers are related to social engineering techniques, so there are many sites that can show you malicious materials and lead to other issues related to malware distributors. Even though this potentially unwanted program is not malicious nor exceptionally dangerous there are many sponsored pages and third-party redirects that can include direct malware or lead to pornographic, advertising, or different malicious material.
Bot-checker.com - the program that creates issues with the system when all the shady advertisements start coming to your desktop directly. The intruder triggers unwanted pop-ups and notifications, redirect windows, and advertising campaign materials.
Creators of such intruders like adware, browser hijackers, general PUPs, and other browser-based intruders like Bot-checker.com virus tend to focus on attempting to fool users into allowing push notifications and advertising materials. These pop-ups and notifications come straight to your desktop if you click any of the buttons, unfortunately.
The misleading Bot-checker.com message claims to be a pop-up to human verification. However, the deceptive message triggers pop-ups after any interaction with the browser window:
You should remove Bot-checker.com, ignore any of those domains, pop-ups, notifications, and messages that this or similar sites show, and try to get rid of the potentially unwanted program that triggers these issues. As soon as you clear the machine, these symptoms should stop. However, PUP can get persistent over time.
Do not think that since this is a potentially unwanted program the process of Bot-checker.com removal is easy and cannot get difficult. Experts talk about how PUP developers and deceptive content creators evolve and make their materials more misleading, intrusive.
You should try to ignore any of those messages and try to get rid of the Bot-checker.com redirect virus. This intruder is nothing but annoying, so you should try to delete the program itself and clear any damage, related programs, or files from the computer.
Remember to check for the damage that Bot-checker.com might trigger on your device to interfere with the persistence and general performance of the computer or even mobile device. When it comes to such issues, PC repair tools or system optimizers are the ones required. Try to run and find or even fix system problems yourself.

How Bot-checker.com ads got into your browser
From our report of Sep 2020 · not reviewed since
Pop-ups, redirects, banners, push notifications, and other contents that come on the screen in additional layers get intrusive and extremely annoying.
However, in most cases, the user has no idea how the PUP that triggers all these issues got on the machine.
The infiltration happens in the background when the user relies on freeware installation sources like torrent services, free download pages and allows various applications to get on the system automatically. You should go for reliable sources like official provider sites or application stores and rely on Advanced or Custom installation options that allow seeing all the bundle components.

Do not let government spy on you
The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices.
Avoid any unwanted government tracking or spying by going totally anonymous on the internet.
You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using VPN.
Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.
Backup files for the later use, in case of the malware attack
Computer users can suffer from data losses due to cyber infections or their own faulty doings.
Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact - you can set this process to be performed automatically.
When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use for the data restoration process.
Questions about Bot-checker.com ads
bot-checker.com keeps sending notifications. Is it a virus?
No. Notifications from bot-checker.com come from a permission stored in the browser, not from a program installed in Windows. Someone clicked Allow on a prompt from that site, usually without realising what it meant, and the site now sends ads through the browser's notification system.
Antivirus scans often find nothing because there is nothing to find on the disk. Removing bot-checker.com from the browser's list of allowed sites stops the messages for good. A scan is still useful if you clicked a notification and downloaded or ran something from the page it opened, because those downloads can be unwanted programs.
The bot-checker.com notification said my PC is infected. Is it true?
No. Notifications from bot-checker.com are adverts written to look like system messages. A website cannot scan your files, so it has no way to know whether your PC is infected; it shows the same warning to everyone who allowed its notifications. Real Windows Security messages name Windows Security in the bottom line, not a browser and a website.
If you want to be sure, open Windows Security from the Start menu and run a quick scan there. Then remove bot-checker.com from the browser's notification settings so the fake warnings stop arriving. Do not call any number or buy anything the notification or its page suggests.
Why does Bot-checker.com show me ads?
Because that is its whole purpose. Bot-checker.com is a push-notification spam site, and its operators are paid for every ad it displays and every click it gets. In this case the ads take the form of desktop notifications.
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.
Is bot-checker.com safe to visit?
No. The site bot-checker.com exists to push visitors towards ads, and the pages it leads to include fake virus warnings, fake updates, prize scams and notification prompts. Visiting it once does not infect an up-to-date PC, but anything you click or download there is a gamble.
Do not enter personal details, do not allow notifications and do not call phone numbers it shows. If it opens by itself, close the tab and check the browser's extensions and notification permissions. Blocking the single domain helps little, because the operators register new names regularly.
Which browser is sending the bot-checker.com notifications?
Each notification shows the name of the browser and the site in its small print. In the cases we saw, the messages from bot-checker.com came through Chrome, Edge and Firefox. Permissions are stored per browser and per profile, so removing the site in one browser does not affect another.
If you use several Chrome or Edge profiles, check each one. If you sync the browser with an account, remove the permission while signed in, otherwise another computer may still hold it and keep receiving the same messages.
How do I know the ads come from Bot-checker.com?
Look for notifications from bot-checker.com. That is the trace Bot-checker.com leaves, and it shows up as desktop notifications. 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.
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.
Did clicking Allow install anything on my PC?
No. Allowing notifications stores a permission in the browser and nothing else. No file is downloaded and no program is added to Windows, which is also why antivirus scans find nothing. The risk comes later, from the notifications themselves: they lead to scam pages, fake updates and phishing forms.
Remove the permission in each browser where you allowed it. If you clicked a notification and downloaded something afterwards, delete that file and run a Microsoft Defender full scan and offline scan.
Will Fortect remove Bot-checker.com?
No program removes Bot-checker.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.
