Well, all I can say is that it’s not a bug, otherwise it wouldn’t be working on my Win 2008 servers either.
Why would you have to set specific protection on some directories, as they are all protected when avast is installed.
Never mind, what you guys should do is probably wipe the installation on these servers by using the uninstall utility and try again. I can’t tell you how many servers I’ve installed 4.8 on and never had a problem. The only problem that I’ve had is either not having them reported in ADNM, or problems installing ADNM on 2008 and 2008 SBS.
