Sophos has announced its top 10 viruses and hoaxes for October, and the top viruses are:
1. W32/Gibe-F (Gibe variant) 22.7% 2. W32/Dumaru-A (Dumaru virus) 13.6% 3. W32/Mimail-A (Mimail worm) 12.4% 4. W32/Sobig-F (Sobig variant) 9.0% 5. W32/Klez-H (Klez variant) 4.4%
There's the usual Windows monopoly but Sophos says: "Gibe-F and Dumaru-A -- both of which pose as security patches from Microsoft support -- are threatening to destroy computer users' trust in Microsoft."
Also, for the first time this year, there's a Trojan on the chart: CoreFloo-C, "which allows a remote intruder to access and control a computer via Internet Relay Chat (IRC)."
