How irritating is this problem? (4 votes, average: 5.00)

This page aims to help you remove “Virus”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

It can be particularly frustrating getting your main browser flooded with ads and page-redirects and also modified beyond recognition with its main search engine, toolbar and homepage replaced by some pesky software piece such as the recently released “Virus”. Many users face a similar problem and a lot of them actually think that the cause behind it is some nasty malware program such as a Ransomware, a Trojan Horse or a Spyware infection. However “Virus” and other apps similar to it, although potentially unwanted and quite annoying, are not really malicious in their nature. The idea behind most such software pieces is that they’d use the user’s browser to advertise stuff such as different products, sites, online services, other software apps and programs and so on. It is typically irrelevant what your browser is since most popular browsing programs like Chrome, IE and Firefox can get “infiltrated” by an app like “Virus”. Also, switching to another browser is likely not going to solve anything as the unpleasant piece of software might latch onto the new browser as well. The best thing to do in case you have  “Virus” on your computer is find a way to have it removed from it and here, we will show you exactly what you need to do in order to bring your browser back to normal.

Browser Hijackers

The name of the software category to which “Virus” belongs is Browser Hijackers. Those are actually really widespread apps and software components that can be found all over the Internet. Since they aren’t real viruses, the methods of distributing them are oftentimes legitimate which makes it more likely for users to get one such app installed on their computer without even realizing it. As we said, the best way of dealing with the pesky ads generation and unwanted changes to the browser is to take away the hijacker. However, doing that might not be all that easy if you have never before encountered and removed a hijacker. Therefore, we have made sure to provide the visitors of this page with the necessary tools for uninstalling and removing hijackers like “Virus”. Below, you can find manual removal instructions as well as a professional removal tool for unwanted and hazardous software. Use either of them or both of them to get rid of the unwanted app.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

If there are suspicious IPs below “Localhost” – write to us in the comments.

  3. Click on Advanced —> the DNS tab. Remove everything here (if there is something) —> OK.



  • After you complete this step, the threat will be gone from your browsers. Finish the next step as well or it may reappear on a system reboot.

Inside, press CTRL and F together and type the threat’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

  • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

The importance of removing such software

Many users don’t actually mind the ads and the page redirects all that much. They are simply able to ignore them and are okay with putting up with them. However, there is actually a more important reason for removing hijackers like than the sheer intrusiveness that comes from them. A browser hijacker, though technically harmless, is not the safest software piece to keep on your PC. Pretty much all security experts advise that users keep away from ads coming from such software pieces because it is possible some of the banners, the pop-ups and the page redirects might originate from sources that are rather unsafe and hazardous. Surely you wouldn’t want to land some more problematic piece of software like a Trojan or a Ransomware due to the hijacker’s presence on your PC, yet this is exactly what might happen if you carelessly click on the ads displayed by the undesirable ad-generating piece of software. That is why, interacting with any content that comes from is inadvisable and also why the best thing you could do if a hijacker app is currently on your PC is use the guide on this page to have it removed once and for all. In addition, it’s important that you don’t allow any more hijackers to get installed on your machine. How to prevent this from happening will be explained in the next paragraph.

Avoiding and other similar unwanted apps

Of course, keeping away from spam messages, sketchy sites, pirated games and programs and questionable web offers and adverts is an essential rule that you need to adhere to if you wish to keep your computer safe and clean. However, as we mentioned above, there are legitimate software distribution methods such as the well-known file-bundling that could also be used for hijacker distribution. Therefore, make sure you always take a careful look at the details in the setup manager of each and every program you might want to install on your PC. In many cases, there would be extra software components bundled with the said program and sometimes a hijacker could also be present in the setup manager. This is why it’s important to use the Advanced setup menu instead of the Default installation option and from there uncheck any optional clauses that might allow the installation of undesirable bonus components.
