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.
