How to remove History Cleaner virus
How to remove the History Cleaner virus 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
History Cleaner virus 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.

Tip: Bookmarks and saved passwords stay, while extensions are turned off and the search engine and start page return to the defaults.

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 History Cleaner virus 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.

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.

Do not tolerate History Cleaner ads and remove the associated adware for your security
History Cleaner is a highly suspicious Google Chrome extension that presents itself as a tool that helps to erase all necessary data in Google Chrome.
However, IT professionals rank it as a potentially unwanted program (PUP) or adware , since it hardly does what it promises. Instead of providing promised features only, History Cleaner might display highly annoying web ads during user's browsing sessions.
History Cleaner virus is a highly suspicious piece of software that should not be kept in the computer system. As soon as it gets a chance to establish itself on victim's computer, it starts tracking user's behavior online.
Typically, the adware aims to find out what kind of websites the victim visits or what content he clicks in them. It can also record search queries and collect time stamps showing how much time the victim spent on particular websites. Such activity allows HistoryCleaner developers select proper ads to display for the victim.
The extension communicates with ad networks and then loads commercial offers on the screen in the form of pop-up ads, banners, or even in-text links. It can be hard to understand that these ads do not originate from sites the victim visits.
However, the number of ads the infected computer generates clearly indicates that something is wrong with the system and that it needs a thorough system scan using anti-malware software like .
You can also try to find and remove History Cleaner manually. To delete this highly suspicious threat from Chrome and get rid of its remains for good, we suggest using guidelines prepared by the 2-Spyware team (you can find them below).

Distribution of ad-supported browser extensions
Unwanted browser extensions similar to History Cleaner (for instance, Always Weather, Noter Save and others) sneak into user's computer alongside vague freeware packages that can be downloaded from the majority of file sharing websites.
It is also possible to encounter a suggestion to install the suspicious program while surfing the Internet if you click on an ad or link leading to the official website of such extension. However, software bundling is a much more efficient technique and therefore it is actively used in History Cleaner's distribution.
To keep this suspicious extension away from Chrome and your computer system overall, always pick Custom or Advanced settings when installing new software. Installation wizards tend to include permissions to install "recommended" programs in Default or Standard installation options, which, to say at least, look trustworthy at first sight.
However, do not let these deceive you and opt for Custom/Advanced settings instead! Here, deselect all extras without any doubt. Dieviren.de experts report that adware similar to HistoryCleaner has used similar infiltration techniques to infect computers of many German-speaking computer users.

Questions about History Cleaner virus
Why does my browser keep going to dieviren.de?
Something is sending it there. On one site only, that site's ads are the cause and leaving the site ends it.
On many different sites, the usual causes are an extension you installed with something else, a site you once allowed to send notifications, or an ad-supported program in Windows that changes how the browser behaves. dieviren.de itself is only a stop on the way: it records the visit and forwards you to whatever advertiser pays most.
Check the extensions page, then the list of sites allowed to send notifications, then Installed apps sorted by date. Removing the cause stops the redirects; blocking the domain alone usually does not, because the network moves to a new one.
Did dieviren.de install a virus on my PC?
Very unlikely, unless you downloaded and opened something from the pages it led to. Redirect domains such as dieviren.de sell your visit to advertisers; they do not need to install anything to make money.
What can be installed is the thing that causes the redirects in the first place, such as an extension or an ad-supported program that came with free software. That is why the checks in this guide look at extensions, notification permissions and Installed apps.
A full scan with Microsoft Defender afterwards gives you a clear answer about the rest of the PC. If the scan is clean and the redirects stop after removing the cause, you are done.
Why does History Cleaner virus show me ads?
Because that is its whole purpose. History Cleaner virus 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 History Cleaner virus 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 History Cleaner virus?
Look for redirects to dieviren.de. That is the trace History Cleaner virus 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.
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.
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.
Can adware slow down my PC?
Yes. Adware runs in the background, loads ad scripts, opens extra tabs and contacts its servers, all of which use processor time, memory and bandwidth. Ad-heavy extensions also slow down every page, because they inspect and change it before you see it.
The effect is strongest on older PCs and when several adware programs arrived together. After removal, restart the PC and check Task Manager for anything still using a lot of resources that you do not recognise. Speed usually returns to normal once the ads stop.
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.
Will Fortect remove History Cleaner virus?
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 History Cleaner virus, 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.
