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.

If you have recently downloaded some not-too-reliable piece of software and installed it using the Default setup configuration instead of selecting the Advanced setup and checking fro bundled components and if after that your browser has began to behave weirdly and has had some changes made to its search engine, toolbar or homepage without you having done anything, then you have most likely had a browser hijacker installed on your computer without even realizing it. Now, do not get panicked as this is not some Ransomware or Spyware infection. Hijackers aren’t technically in the same category as viruses the likes of Trojans, Rootkits, Worms, Ransomware and so on. In the majority of instances, the worst that could happen if you have a hijacker on your machine is that your Chrome or Firefox or whatever other browsing program you use would get spammed with page redirects and ads while you are browsing the Internet. And while this might indeed not sound like a lot, you should still bear in mind that the irritation from the changes to the browser combined with the obstructiveness of the ads generation could really get on your nerves and make you feel frustrated. A particularly unpleasant traits related to the browser hijacker class is that most such apps are rather difficult to remove from the browser and uninstall from the PC and on top of that, unless you make sure that the hijacker gets eliminated, your browser would likely continue to get spammed with pesky advertisements, page redirects and the changes made to it would not go away.

That is why we have made sure to offer our readers a detailed, yet easy to use removal guide for one particular hijacker known under the name of “Virus”. The reason this is going to be the focus of our guide is because “Virus” is one of the newest and also one of the most annoying browser hijackers that you could currently come across on the Internet

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:

Drag and Drop Files Here to Scan
Maximum file size: 128MB.

This scanner is free and will always remain free for our website's users. You can find its full-page version at:

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.

Type msconfig in the search field and hit enter. A window will pop-up:


Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.


To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.

Keep your distance from the ads!

You can never be hundred percent certain if a given online ad isn’t actually unsafe to click on and this is even more true when talking about hijacker-generated ads. might indeed not be a serious virus infection, but you definitely shouldn’t risk your PC security by clicking on its pesky advertisements. Many creators of malware and many online scammers rely exactly on easy-to-mislead users who will click on the malware-carrying ads and get their machines infected. Now, we are certainly not saying that all ads by are guaranteed to be harmful and unsafe – not at all. However, the very fact that there’s still a certain chance some of the advertisements and the page redirects could be compromised should be enough for you to avoid the hijacker-related ads. Also, it’s important that after you uninstall you make sure to avoid unreliable download sources, sketchy online content and obscure websites so that you don’t get any more hijacker app installed on the computer. Paying attention to the setup options for any new programs you want to install is also crucial since many hijackers actually get bundled with legitimate software.
