PoLak:

I went to http://download.microsoft.com and downloaded Windows XP SP2 and ran that on my computer. It over wrote the older one, & since then Avast works. Microsoft sites states use the Autoupdate feature for single user, but the Autoupdate icon on my computer did not progress beyond 3% since last night. So today, I downloaded SP2 around 275 MBytes.

Vlk Thanks, Could you remove the screen image that I posted. I notice that my C:\WINNT folder is around 2.5 GBytes, Is there a way to remove SP1, I presume this SP2 wrote over the previous SP2 becoz it did not ask me for archival.

I am impressed with Avast, I recommended to our Public Library administrator to not renew Norton License next year instead use Avast. Lets see what she does with it.

Good Job Guys.
