Any help is very much appreciated!!!
Thanks!!!

Your log looks clean to me. That doesn't guarantee you don't have a virus, it may be well hidden from HJT. But your virus seems to be a generic virus alert from heuristic search, hence it could be a false positive. Please locate the file and upload it to http://virusscan.jotti.org/ , then post the result here if something's being found there.

The file is in use, so it can't be deleted. If you want to get rid of it, try running AVG in Safe Mode or manually delete it there. But since it's in use, it may be a file you need. What's the filename?
