Whenever I run my AVG scan now, the status for shell32.dll says "changed" and result says "change". Does this mean I have a virus of some kind or something? it says no virus and I've scanned with all my spyware scanners too. edit: I just tried the different "system scan" and it popped up asking about change, and I confirmed it and now it scans as ok. the file size had changed. but I don't understand whether it changed it back or if it's still different. it didn't explain anything.
