UUUuuugh sorry had a few its actually clamwin go dl it here http://www.clamwin.com/ its a GREAT antivirus prog that works very effing well with AVG (also free) If you ever get a notification from AVG (ESPECIALLY with EXE's, AVG will give you alot of false positives) don't immediately dump the file, check it first with Clamwin, you must run the program (after installing, when right clicking on an exe, you should now see the option to check with clamwin) Exe's can carry some nasty payloads that won't show up 'til they're executed. Remember to COMPLETELY delete that program i.e. search registries, program folders, etc then try a reinstall. I would bet my life that you don't have corrupt media, just invalid entries from "ahem" more than one attempted install??? Also, I can't guarantee clamwin's performance with any other real time scanning antivirus progs, just AVG, which is prob the best (maybe close second to Kaspersky, but better price FREE) What part of town do you stay in? I would be more than happy to test that software for you in exchange for a cold beer or something!
