Running XP and it worked fine!!!
Here’s what I did. I opened the program and it said a new version was available. Than I got out of Avast:
1.) I than created a System Restore Point, naming it “Before Avast Update.”
2.) I turned off all the Behavior Shields Right-Click Avast Ball/Avast Shield Control/ Selected “Disable until System Restart.”
3.) Closed the warning balloon that poped up from the Windows Security Center that my AV was disabled.
4.) Opened Avast 5 and clicked “Update program.” Download went fast.
5.) BUT instead of answering “Yes” to “Avast needs to restart your computer, do you want to do it now?” I said “no” to get out of the program first, waited 30 seconds and than rebooted.
Hint: Before you update the program from within version 5. Disable the system shields. The shields might have been the conflict with the new version for some users.
