I downloaded the free version of AVG 7 last night. It downloaded fine and uninstalled AVG 6 in the process. When I ran the first scan however, it came up with virus found Trojan Horse Dropper.small.7.j. It wouldn't quarentine or delete it however. I then ran spy-bot and ad-aware, neither of which fixed it either. I then ran Housecall which found something called JAVA BYTEVER.A. but it said something to the effect of file being used and it wouldn't do anything either. So now I wasn't sure how to get rid of this thing. After spending an hour or so doing web searches I came across the answer. Went into Control Panel to Java plug-in, clicked on cache, clicked on clear and problem solved. Ran everything again and it was all clean. I don't understand the technical details and I've never had reason to go into the Java Plug-in cache and clear it, but it worked and everything is fine now. Thought I'd pass it on in case anyone else see's the same thing.
