The top ten virus threats for August are dominated by Trojan viruses.
The main threat according to BitDefender is Clicker.CM. an ad-serving Trojan while three variants of the Wimad Trojan downloader, which gives the appearance of a codec downloader, are prevalent.
The Trojan.Qhost.AKR, a piece of Malware that is aimed directly at BitDefender users and tries to disable the antivirus update feature, was the fifth most seen while a generic detection for a Flash exploit and a Trojan.Swizzor.1 were next.
An ActiveX exploit was the eighth most seen, which tricks the browser into downloading and installing malware by targeting an ActiveX control called SinaDLoader.
The last two most seen were Trojans, the ninth was one that spreads via P2P file sharing while the tenth was a downloader for a fake antivirus package called ‘XP Antivirus'.
Sorin Dudea, head of Virus Research at BitDefender said: “XP antivirus has previous form. It used to appear with a valid digital signature and a lengthy EULA, from sites with security-related names. As such it was somewhat of a champion in the social engineering area, convincing victims that it was in fact a legitimate piece of security software.
"Measures taken to revoke the malware's digital signature by GlobalSign and the denial of anonymity to the people who ran sites hosting it by Directi, seem to has put a dent in the operation.”
