How to remove Antivirus8 malware (Uninstall Guide)

Antivirus8 is a rogue anti-virus program that deliberately reports false system security threats to make you think that your computer is infected with malware. This fake security program claims that your computer is infected with keyloggers, Trojans, email worms, spyware, adware and other malicious software that may steal your passwords, delete important files or download additional viruses onto your computer. Antivirus8 is promoted through the use of Trojans, fake online scanners, infected websites and spam emails. The rogue program may come bundled with other malware as well. It goes without saying, that if Antivirus 8 has infected your computer you should remove it immediately. And, of course, you shouldn't purchase this bogus program. Please follow the removal instructions below to remove Antivirus8 and any related malware from your computer.

Once Antivirus8 is installed, it will pretend to scan your computer for malware. Like all the other rogue security programs, it will claim that your computer is infected and that you should purchase the full version of the program to remove found malware and to protect your computer against security threats from the web and emails. What is more, it will constantly display fake security warnings and notifications about active viruses and threats on your computer. Here's how Antivirus8's alert reads:
Antivirus8 Resident Shield: Virus detected
Warning! Active virus detected!
Threat detected: Backdoor.POISON.BQA
This copy of AV is not genuine
Your may be a victim of software counterfeiting. This copy of Antivirus8 is not genuine and is not eligible to receive the full range of upgrades and product support from Microsoft.
Warning! New Virus Detected!
Threat Detected: Email-Worm.Zhelatin





While running, AV8 will block nearly all programs on your computer. It will hijack your web browser and display fake warnings while surfing the web. It could be that you won't be able to download and install any anti-malware software on your computer. In such case, you should reboot your PC in safe mode with networking, download anti-malware software from the list below and run a full system scan. If you can't reboot your computer in safe mode then you will have to download additional tools (i.e. Process Explorer or HijackThis) to end the main process of the rogue program which is av8.exe. Then you should be able to download anti-malware software onto your computer (see removal instructions below). Please note that Antivirus8 may infect system restore points. We strongly recommend you to purge all system restore points and create a new one when the rogue program is completely gone from your computer. If you don't know how to delete system restore points then please follow the steps in the Microsoft knowledgebase article http://support.microsoft.com/kb/310405.

Antivirus8 is from the same family as Antivir 2010 and AntivirusGT. It costs $79.90. If you have already purchased this bogus program then you should contact your credit card company and dispute the charges. If you have any questions or additional information about Antivirus8 please leave a comment. Good luck and be safe online!
