Wow. That’s a relatively nasty worm. It concerns me that avast didn’t catch on a normal scan. As suggested, set your on-demand scanner settings to thorough and search those folders.
Does anyone have any ideas why that worm wasn’t caught?
Hmm…I hate to follow up my own post but it appears that only Gibe-A is in the Avast VPS, so perhaps that’s why Gibe-F was not caught. Or, are they similar enough that the Gibe-A signature should have allowed Avast to catch the other variants?
If you believe this is an undetected virus, then if you can zip and password protect (‘virus’, will do) the suspect file and send it to virus @ avast.com (no spaces).
Give a brief outline of the problem, the fact that you believe it to be a new virus and include the password in the body of the email. Some info on the avast version and VPS number (see about avast {right click avast icon}) will also help.
