Vundo (also known as VirtuMonde and VirtuMundo) is a malicious software application that combines both adware and trojan characteristics. Vundo is wide spread today and is probably one of the hardest programs to get rid of. Once installed, Vundo downloads and displays pop-up advertisements that often promote questionable computer-enhancement programs or fake anti-virus or anti-spyware utilities. Lately, Vundo has been advertising several rogue programs called WinFixer2005, WinAntiVirus Pro 2006, WinAntiSpyware and RazeSpyware. Be careful could be infected!
