How irritating is this problem? (6 votes, average: 5.00)

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

If you are here because an undesirable app/software component named Adware Virus has replaced the search engine or the homepage of your main browser and has started to display different irritating adverts and page redirects on your screen, then know that we understand just how unpleasant this could be. In fact, there are a lot of people out there who are familiar with the experience of having a browser hijacker such as Adware Virus on their computers. A browser hijacker is an application, a program, a browser extension or any other type of software piece that could be added to the user’s browser with the purpose of exploiting it for its advertising campaign. Unlike most regular browser extensions that could typically function only on one or two similar browsers, an app like Adware Virus could get added to pretty much any browsing program you could think of. Chrome, Firefox, Opera, Edge, IE and so on and so forth – there’s hardly a browser that the majority of hijackers cannot attach themselves to. However, here we aren’t talking about an actual malware infection since browser hijackers are not technically viruses. Therefore, there’s no real reason to get panicked if you’ve recently found out that Adware Virus or any other similar app is residing on your PC. This isn’t some scary Ransomware or some highly-dangerous Trojan Horse infection and there will likely be no long-lasting signs of the hijacker’s presence on your system after you’ve removed the undesirable software piece. However, if you’ve already tried to uninstall the pesky app yourself, you have likely found out that doing that isn’t all that easy. Hijackers are well-known for being quite difficult to get rid of. It is also typical for them to “reinstall” or “re-attach” themselves to the browser even after the user has managed to seemingly remove them. However, difficult doesn’t mean impossible and we will prove that to you down below, with our guide for removing the Adware Virus hijacker. The reason we are mainly focusing on Adware Virus is because it is currently one of the most widespread representatives of this software class and also because a big number of users have made complains about it in the recent days.

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:

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.


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:

hosts_opt (1)

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

Open the start menu and search for Network Connections (On Windows 10 you just write it after clicking the Windows button), press enter.

  1. Right-click on the Network Adapter you are using —> Properties —> Internet Protocol Version 4 (ICP/IP), click  Properties.
  2. The DNS line should be set to Obtain DNS server automatically. If it is not, set it yourself.
  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.

Right click on the browser’s shortcut —> Properties.

NOTE: We are showing Google Chrome, but you can do this for Firefox and IE (or Edge).


Properties —–> Shortcut. In Target, remove everything after .exe.

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.

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

As you can see, there is quite a lot to e done before you can be sure that the hijacker has been thoroughly taken care of. However, we understand that the steps from the guide might sometimes not work perfectly or that some of you might not feel confident enough in their computing skills in order to complete the whole guide. This is why, we have placed a removal tool for unwanted software inside the guide – the automatic security program could help you detect the pesky app and remove it in case you need the extra assistance from it.

Make sure you remove the hijacker

In the end, it doesn’t matter which method you decide to go for – the manual steps or the removal program. The important thing is to make sure that the pesky hijacker app is no longer present on your computer. The reason for that is the security hazards Adware Virus or any other similar software piece could bring you. Now, again, we need to remind you that this isn’t some kind of a Trojan Horse, a Ransomware, a Spyware or some other insidious and malicious virus program. However, ads like the ones that normally come from hijackers aren’t the most reliable types of online content and it is inadvisable that you interact with them even if a certain offer looks attractive and legitimate. Although most adverts and page redirects are likely not going to put your system at any risk, there are still those online ads that could potentially link you to shady, questionable and maybe even illegal sites – something that could really threaten the security of your PC. Therefore, the best way to avoid putting your machine at risk would be to eliminate the source of the advertising materials.

How you could land an app like Adware Virus

Despite the fact that a lot of browser hijackers actually have official sites and pages whence one could download them, it is more common for such apps to get distributed through methods such as spam messaging, malvertising and software bundling. This is why it is so important you do not go to obscure online addresses, open any spam letters and download low-quality or pirated software. Also, even when you are about to install a legitimate-looking program, remember to take your time to study its setup configuration details and see if there aren’t any bonus software components bundled with the installer which might be unwanted. If there are any, you should, of course, disable them before you go on to install the main program from the installation package.
