Yesterday, I tried to DL http://files.avast.com/iavs4pro/setupengpro.exe and its version 5 instead. :o
edit…Crap, sorry, I just relized this is the server forum… OP please delete after fixing problem or move to right place.
Are you sure that that is version 5.0 pro as the direct link for 5.0 pro is http://files.avast.com/iavs5x/setup_av_pro.exe ?
Obviously I can’t check being on dial-up it is too big to download just to check.
Yep, I dowloaded it, started it, it was 5.
Is there any reason you want to stay with 4.8 ?
See this topic of a pre-release update of avast 5.0.492, if you had any problems with 5.0 there are a number of fixes, http://forum.avast.com/index.php?topic=58183.0.
