This page aims to help you remove Weevah2 Virus. These Weevah2 Virus how to remove instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Weevah2 is a type of software that could take over all your browsers – Firefox, Explorer and Chrome (and all the other browser apps); and may cause some very irritating changes to these apps:

  • You may get redirected to unfamiliar web pages every time you try to open a selected website that you wish to visit. Thus, your entire browsing experience could be affected. 
  • Your browser apps might begin to broadcast too many online ads. Pop-ups, banners and colorful boxes could appear all over your browser whenever you try to browse the Internet;
  • Weevah2 may even substitute the browser homepages and search engines you have always used with new ones – often unrecognizable and seeming annoyingly to you.

This program’s type is a browser hijacker. The good news is that generally, these programs are not among the most disturbing online threats. However, the “bad” news is that they will play with your nerves by showing you ads and sending you everywhere on the web unless you uninstall them. Browser hijackers represent a type of software, which is strictly oriented towards browsers. Really, no other component of your system could be affected by such a program. Weevah2, as a typical representative of this software group, is only able to change all your browsers – nothing less and nothing more could be performed by it.

What you probably don’t know about Weevah2

You might not be aware of the fact that all of the programs from the hijacker family are actually serving the marketing industry. The mutual efforts of goods manufacturers, service providers and programmers to keep up with the increasingly online-based communication have led to the creation of such programs. In fact, we should consider them equal to the promoting campaigns conducted on TV and on the Radio. This collaboration scheme has been named PPC {pay per click} and its name explains how it works. The more ads you see, the more redirecting that you experience and the more new homepages are set; the more successful the advertising process is considered.  That’s why programmers could make their browser hijackers work a little more intensively,in other words intrusively – to make more money from them. In fact, there is really nothing you should worry about and we will give you some actual proof of the harmless nature of Weevah2 and its siblings in the text below.

Is that program simply potentially unwanted or really dangerous?

We are positive that Weevah2 does NOT represent a version of malware. As far as we know, this program is just an advertising tool and cannot do you and your PC any harm. In order to avoid simply making empty statements and to point out the contrast between any browser hijacker and any very malicious program, we are going to show you how Weevah2 differs from a Ransomware-based virus. There are many differences when it comes to these two programs, but the most serious ones concern the way hijackers get spread and the way Ransomware viruses are distributed; as well as the way they affect your system in general. For instance, when it comes to the distribution differences, we must point out that viruses are able to automatically self-install on your PC, while every single Ransomware will need your direct/indirect permission and its developers will always look for a way to trick you into including it into your system. Another example deals with the way Weevah2 and a typical Ransomware may affect your PC. While the hijacker might only “hijack” the control over your browsers, Ransomware will actually hijack all your regularly used files and block you from accessing them, requiring a ransom for their decryption. No hijacker is capable of such harassment.

Places where Weevah2 tends to lurk

Still, you will not need such a persistently annoying piece of software on your computer. And the best way to deal with a hijacker is to never catch it in the first place. In order to successfully prevent your machine from getting infected, you need to be aware of the potential sources of such software. When it comes to Adware and hijackers, the greatest source is bundling. Bundling represents putting numerous games and apps together and spreading them in a set, called a bundle, usually for free. Such bundles are harmless if you know how to install them right. In this way you will benefit from the free software inside them and avoid the advertising programs. The tip is: no matter what you install on your system, do it in the slower but more detailed way – by selecting the ADVANCED or the CUSTOMIZED installation method.

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.

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.

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

If the guide didn’t help you, download the anti-virus program we recommended or ask us in the comments for guidance!

  • This doesn’t tell me anything about how to remove this in Fedora, Debian, Ubuntu, or any other distribution of Linux in which I’m running the Chrome browser (in Linux it doesn’t seem to affect any other browser and occurred in Chrome almost immediately after chrome was installed and I logged in with my Google account, which synchronized my addons and apps from those installed on my Windows machine). This is one of the reasons I’m slowly moving all of my platforms to Linux, but there are just some things that need the Chrome browser to operate correctly. It looks like Google needs to make some effort in locking down their browser otherwise others like myself will be looking for more alternatives to Google’s apps and browser.
