last evening my AVG resident-shield alerted, when i entered a site to try to download a program. it said that it had deteced a trojan known as: "downloader.agent2.IGX". -AVG could not remove these files through multiple scans/repairs - i then ran the "8 steps" successfully. (doing scan twice).- and came up "clean" - when can i know that i got rid of "bugger"? - thanks for any help.
