VirusBuster, the Hungary-based specialist of IT security continuously monitors virus occurrence and activity. Data from VirusBuster's mail protection systems -- in-house and externally deployed alike -- is collected and processed. VirusBuster uses the results to generate monthly statistics of the most frequent infections. These monthly virus toplists are published on the company's website as well.

"Our analysis shows that, in August, Hungarian users were mostly attacked by the members of two populous botnet families: Zbot and Bredolab. Last month's toplist is also colored by some older malicious programs, including Worm.SdBot.GAP, Worm.Rbot.MCG and Backdoor.IRCbot.AECD", said Gábor Szappanos, the head of VirusBuster's virus lab.

Botnets (short for robot networks) are networks of unknowing victim PCs (called zombies) controlled by hackers. Users should get rid of botnet malware as soon as possible, since otherwise they may become accomplices in cybercriminals' activities, warned Gábor Szappanos.
