Do I need to uninstall the 4.7 version before I install the 4.8 version?
THANKS
That might be a good idea considering other posts I have read about upgrade problems.

That is the problem with support forums, you don’t see anything about those who have had no problems at all updating to 4.8 ;D
If you have win9x or winME then perhaps it is a worthwhile option as they seemed to have the lions share of update issues otherwise I would just update.
Shortly, you don’t.
My suggestion was only meant as a precaution, there is no way of knowing who will have problems and who won’t. I had problems when I upgraded from 4.6 to 4.7 and I wonder if I wouldn’t have if I had uninstalled 4.6 and then installed 4.7 “cleanly,” so to speak.
No disrespect was intended.

Sure, we don’t understand this way. Your help is welcome.
That is the problem if everyone errs on the side of, it might go wrong so I best uninstall/reinstall then we would never find if a) there were any problems (that can be fixed) and b) we would become like so many other applications that require a reinstall on program updates.
This is one of the things I like about avast, the incremental updates (VPS and Program) extremely important to us dial-up users.
No offence taken, you did notice the smiley ;D and I also qualified my comment relating to win9x and winME users.
So is yours, tech.
You and DavidR (and many others) know quite a bit more than I do about Avast and antivirus program workings in general. It’s pretty cool to see you guys at work. 8)
