Financially motivated threats the most frequent malware in June

According to PandaLabs, Trojans and adware accounted for 49.6% of infections detected by Panda ActiveScan in June. Trojans, which increased by 0.75% this month, caused 26.89% of infections, whereas adware was responsible for 22.72%. These figures prove that most new malicious code is mainly created to fraudulently obtain financial benefit.  

Other types of threats move along the same parameters as in May, with worms taking third place in the ranking (8.71%) followed by backdoor Trojans (3.87%), dialers (3.34%) and spyware (2.99%). Bots appear at the end of the list with 2.58% of infections.

In terms of the ranking of June’s ten most virulent malicious codes, Downloader.MDW is the undisputed leader. This Trojan is designed to download other malware onto computers. In second place comes the familiar Brontok.H worm. After this comes Sdbot.ftp, the script used by this family of worms to download themselves via FTP. Having risen four places since last month, it is now dangerously close to the top of the list once again.
 
In fourth, up one place from May, comes the Puce.E worm which spreads across P2P networks. Next is the Dropper.UN Trojan, rising from ninth place in the previous month. In sixth place is Perlovga.A, this Trojan designed to steal personal data is new in the ranking. Another new code, the Lineage.BZE password stealer, is in seventh place.
 
PcClient.DU, the only backdoor Trojan list, comes next. Ninth and tenth places go to Downloader.NOE, down five from last month, and another new entry, Lowzones.TP.
