Beginning on December 1, 2018, new Avast/AVG Antivirus products will no longer be delivered for the Windows XP and Windows Vista operating systems.
Why?
I've been using Avast Pro for a number of years on 2 computers Windows XP and Windows 7. Its always installed and worked. The compatibility is still Windows XP.
The only reason I use Avast is the license can be used on 3 computers. All other anti-virus software to pay again for each computer.
There are bugs in the software for the same application ETKA. I've reported this when the popup shows suspicious activity. The reply says thank you it will be look at for the next update.
This is total bull as it isn't an application exe its a software update exe. I scan all files and Avast shows all clear. I have to disable Avast before I download the files and update.
