Well, I used the Uninstall Utility to remove all Avast versions on my PC, and install the Avast Free latest.
Yet, it has given me problem today. It is unable to update the virus definitions. So, I went to Remove Program and did the update there and was successful. (you guys should try that too, instead of updating it at the Avast Control Panel).
Before the successful update, my Windows Security Center flagged my anti-virus is not installed, but Avast was running fine with all the Shields running, except the Firewall (which asked for payment to activate it).
Now that I've successfully updated the Avast virus definitions, the Windows Security Center red alert icon is no more there. Good.
So, my question is that Avast flagged me telling that I've a previous version on my PC and I should uninstall it so that Avast can perform it its best.
But I'm sure I've uninstall all versions.
I really hate going to safe mode to uninstall Avast with the Uninstall Utility all over again, as it screwed up my network connection the previous time I did that. I had to reset my PC to get my network connection back.
Is this a bug or did Avast keep remnents of its software on my PC that even the Uninstall Utility tool cannot uninstall completely?
