Been running a healthy Avast Pro 4.8 on XP Pro SP3 and running perfectly. Downloaded 5, uninstalled 4.8, rebooted and then installed 5. First, 4.8 License Key is no good.
No way to fix it within the program. (I know there is a link to get updated. It leads to a password protected dead end.) Then, the installation froze. >:( I waited nearly 4 minutes before having to Power down via power switch. Booted up ok and said it was installed and ok but don’t trust it after having to kill it so hard. :-X
I knew I should have waited for a few weeks but thought I would get along ok. : Didn’t happen!
As I could not find a version 4 Pro download link, I went back to a different AV for now. When is the next build coming out? How do I get a valid license key for 5 when the version 4 one is worthless?
