Hey “guys!”
My wife and I have used the free Home Edition for several years now; however, we need counsel as to which edition we should use for the business. We work for a small business (two computers w/Windows XP). They are networked together with the main computer being used as the server. We just want anti-virus software. Please advise and thanks from Wyoming, USA
I think two licenses of the Professional version would be enough… locally installed in each computer 
Well, you’ve used avast! for years and only now discovered the forums? :o
Better late than never ;D

If your computer use/configuration is going to be the same, e.g. “They are networked together with the main computer being used as the server” you mentioned.
If you are able to use the Home version in this configuration (e.g. it currently has stand alone version of avast on the computer being used as a server) then you would only need two Pro licenses as Tech mentions.
