Thaniks for the reply Eddy,

Operating system is Windows 7 Home Premium SP1
avast! Pro is version 2014.9.0.2007 - virus Definitions 131104-2

Reason I’m wanting to know if avast! Pro pops up an “ILLEGAL” license warning message, with offer to buy a legal license for the prices quoted in my original post, is to determine whether I need to contact the PC owner about her antivirus software being illegal, and to ask if she wants to buy a legal license for the prices offered.

If avast! Pro doesn’t have a warning popup as described, I can assume the warning message is bogus, and I need to do more cleanup before returning the PC to the owner. Other than that occasional warning popup, avast! Pro indicates there are still 300+ days remaining on the current subscription, it updates definitions as it should, and seems to be functioning as it should. I’ve contacted avast! tech support by phone and they were no help at all. As far as removal and reinstallation goes, IF the warning popup is legit, I’ll contact the owner to find out if she want to buy a new license,
