czardes,if you have done with your non-helpful rants,take the pain of sending the flagged files to virus@avast.com for analysis so the virus lab can fix the false positives. 
What 3rd party software?? mcshield!? well,you know what that is a cleansing tool something that normal AV’s cant do.If you cant follow simple suggestions its your problem not ours and besides at some point you will get tired and stop your rants instead of following advice given to you.
