Had the same problem and I have AGV antivirus aswell. Check
www.free.grisoft.com, this is an update site for AGV, go to "I need help" at left, then go to "virus encyclopedia" type in "Padobot", that will give you info on the virus, apparently it is also called Worm.korgo.
Check out
www.pandasoftware.com, thay have a free online virus scan that is helpful, virus info in the top tab, and other helpful stuff on their webpage. Also, housecall.trendmicro.com is another free online scan.
When you scan your pc turn off your system restore and reboot in safe mode, then run your scan. some programs will not run in safe mode, I found on my computr that AGV is one of them, so if it doesn't work for you, scan with another program. I use Spybot, Zonelab, And Lavasoft adware, each one does something alittle different.
The reason for turning off your system restore and scanning in safe mode is that some viruses can hide in way in the background.
I would recommend keeping your system restore off, but, and its a BIG BUT, everytime you download anything from the web, turn on the restore point, that way you have a restore point if downloads cause problems and removing them doesn't help.
Another free antivirus is
www.avast.com, if I remember correctly , there are some viruses they don't fix.
Hope this is helpful
