Security experts warn of Vista-specific malware

Sophos reported that one Vista-affecting baddy, the Stratio-Zip worm, overtook Netsky-P as the most widely circulated piece of malware, accounting for one-third of the total threats reported.

Following Stratio-Zip by a long way is Netsky-P, which is then followed by Bagle-Zip. Zafi-B is in fourth place, followed by Netsky-D, Nyxem-D and MyDoom-O. Eighth place goes to Mytob-C, then Sality-AA and Zafi-D is in tenth.

"No operating system is 100 per cent secure as a standalone system, as end users utilise various alternative applications such as independent email clients, instant messaging, file sharing and more that open new doors for hackers," said Ron O'Brien, senior security analyst at Sophos.
