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. “Virus” is what most online security experts would refer to as a browser hijacker which might sound scary to some of you but what you should know about this type of software is that browser hijackers are actually not as harmful as some users might think they are. A hijacker app is different from a real piece of dangerous malware (think of Trojans, Ransomware, Worms and Rootkits). Instead, browser hijackers the likes of “Virus” tend to be more annoying than actually harmful. The main issue with them is their tendency to mess with the users’ browsers. This includes browsing programs like Firefox, IE and Chrome (as well as most other browsers out there). Among the most common effects that a hijacker app might have on your browser are a replacement of the default homepage and of the search engine tool of your browser. Page redirects, nagging ads, banners and pop-ups showing on your screen while you browse the Internet are also likely to bother you if “Virus” has managed to get installed on the computer and added to your browser. The good news here is that the unwanted changes and the pesky ads will go away the moment you manage to remove the undesirable software from your computer. However, since most hijackers tend to be somewhat tricky to uninstall, you might need some assistance with that. However, you shouldn’t worry about removal as we got you covered – our guide right below has been specifically written to help people who have had “Virus” installed on their computers and are struggling with its removal and uninstallation. Also, if any of you find the instructions too complicated or difficult to execute, we should also mention the suggested removal tool that has been added to the guide – aside from taking care of “Virus”, it can also fend off other potentially unwanted apps in the future.

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.

  1. Right-click on the Network Adapter you are using —> Properties —> Internet Protocol Version 4 (ICP/IP), click  Properties.

  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.

Type Regedit in the windows search field and press Enter.

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

Do not underestimate a hijacker

There is no reason to panic or worry if a hijacker app has been installed on your computer but this also doesn’t mean letting your guard down. Hijacker software is known for its uncontrolled advertising campaigns and you must always keep that in mind. Not all online advertisements and page redirects are safe and some of them might even lead you to sites that spread noxious viruses and other malware like Ransomware cryptoviruses, Rootkits and Trojan Horses, to name a few. Therefore, even if you think that you can tolerate and put up with the annoyance from the ads and the changed browser components, you are still advised to remove the hijacker due to the security issues it might still bring even if it’s not a virus.

Also, make sure that, from now on, you only download quality software from dependable sources and developers and also that you check the Custom setup options of each installer so that if there’s some bundled component that might be unwanted on your PC (such as a hijacker or an adware) you’d be able to leave it out before the main program gets installed.


Type  Browser Hijacker
Danger Level Medium (nowhere near threats like Ransomware, but still a security risk)
Symptoms  Typical symptoms are heavy ad-generation on your screen while you are browsing the Internet as well as unwanted and unauthorized changes to your browser program.
Distribution Method Mostly via misleading web ads, software bundles, different misleading online offers and downloads prompts, spam messages, etc.
Detection Tool

If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!
