Wow, umm, ok...lets respond..ready?
#1 JaneWay: WinXP Pro.....
FYI....pretty much all the sh*t you're using now was tested and developed on XP Pro.
This is not subject to debate..it is a fact. As I stated, Microsoft has NEVER released ANYTHING that did not
require patch/security updates. This includes your wonderful Win7, which was beta tested about 3 years before YOU heard about it. Vista was a hurry up release to save face with the stock holders. 'Nuf said there.
#2 DavidR: Ty for your response. I am aware of this fact, I chose to keep the modules intact for program update purposes. Because I do not use them now, does not mean I will not in the future. I like avast and am one of the few who realize that ALL software needs a break in period. The new v.5 seems to already have gone thru a couple of revisions eh? I was hoping that people would put these troubles in perspective, and not wipe good software just because it needs a little tweeking. Really what worked for me was turning off the auto updates. I would suggest that the good folks at avast may wish to look into it a bit. Also, when the software did the program update, it failed to reboot the system. I had to do a logic service shutdown/reboot manually, which is probably something the average user does not know how to do. Once that was done, my system came up just fine, avast still intact.
Soap box done

Edit: ANd just for the record...it is not the size of your system, but the knowledge of the operator.
Try to keep that in mind.
