I have used Avast home edition for several years on all my computers here at home. (My Wife and both kids have their own computers) So decided to support the makers of Avast with my Cash. We use our computers for gaming mostly. 
I spent the few bucks and upgraded to the Pro version. Does the Pro version find and kill virus better then the home edition?
Hello and Welcome
The detection rates of the both versions are the same, because and both versions use the same engine 
For comparison between Home and Pro versions see HERE
Thanks for the quick reply.
