Hey all, just picked up what looks like a fun little bug. AVG reported a few threats, cleaned them, a few more, noticed microsoft.com wasn't loading, ran a full scan, then it reported loooads of Zbot.g infections. I've since disconnected from net, removed / cleaned anything that came up in AVG, uninstalled AVG and was about to run ComboFix (seems to be the suggested solution in most threads) until I realised it wasn't XP x64 compatible. So now I have an XP x64 machine, no AVG on it, and zbot.g probably still doing whatever it does, so if anyone's kind enough to help out I'd be very happy First up - what's best to do right away (other than ripping out the cat5, obviously). Should I get AVG back on? Should I turn off th PC or keep it turned on (I never like rebooting things unless it doesn't start up, or does something worse). I have files on a seperate drive/partition, though none looked infected - should I physically remove the second drive? Also all files / virus updates are being put on to the machine via USB stick - should I treat this as infected and run virus scans on it etc too? Worst comes to worst, I can re-install the OS, just trying to save time by trying the easy things first Thanks for the help. EDIT: Rebooted once. Haven't killed it yet. Just half the programs Soo what next, reinstall AVG? Run loads of random scans (seems you liek that kinda thing ) ) ? Or just re-install the OS?
