It won’t update to 9, stays at 3 when I try.

I also want to add that I am spyware free which was my very first thought when this problem started.

My stepson’s PC has the same updates and he’s having no problems. We’re networked together on a hub with cable. We’re both using microsoft’s firewall that came with service pack 2. I’ve tried enabling/disabling but that doesn’t solve the problem. I can’t figure out what I have on my computer that’s not on his that’s conflicting with avast!

I’m using default settings.

I’ve got to leave for work now and won’t be able to give you any further details until late tonight/tomorrow. TIA for the help.
