Please provide more details on 'doesn't work'. If you log on as an unprivileged user, and you manually run vps update, does it do anything? Any error/non error window?
Have you checked the setup.log file in setup directory? It does contain lots of details about the process and it should also show the user under which the avast.setup process was run.
Is there any proxy on your system which may be differently configured for admin and for 'plain' users?
Doesnt work: Avast dont update the virus database automatically.
If I run the "iAVS Refresh" command manually, it works perfectly, no error.
There IS a squid proxy, but it only denies internet access for the users "test" and "guest". Any other users (admin and plain) have full access. I dont think that its a proxy issue. If my proxy settings are wrong, then why is maual update working?
I will check setup.log tomorrow.
