Anti-Virus-1 Virus Remoal Guide

Description: Anti-Virus-1 is rogue security application that uses scare tactics to try and induce users into paying for its license. Anti-Virus-1 reaches the user’s system via Trojans such as Zlob and Vundo that get downloaded by exploiting browser weaknesses as well as fake ActiveX Video codec packs. Once installed, Anti-Virus-1 performs a large number of fake security scans on the system and comes up with a lot of fake infections which it claims are plaguing the user’s computer. An endless stream of fake security pop-ups are also shown from the Windows Taskbar, claiming that the computer is under attack from malicious software. The aim of all this activity is to try and get the user to purchase a license to the ‘full’ version of Anti-Virus-1 by claiming that the currently installed ‘trial’ version is insufficient to remove all the detected ‘threats’. However, the so-called ‘full’ version of this threat is just as incapable of cleaning out any computer system as the ‘trial’ version is.
