I've recently bought a new computer and moved over to XP and I have encountered this problem:
When Avast comes across a virus, everything seems fine and it deletes it ok. No sign of any trouble.
Then apon the next reboot of the computer Kerio 2.1.5, apon loading, pops up an error message of "PfVarLibInit: var_server_start error: 1 (10022: socket() failed)", then when Avast loads I get an error along the lines of "Error 1002" outlining that POP3/SMTP features will be unavailable.
It actually totally impairs Kerio and I can't access many things within windows including the internet/task manager until I have sucessfully uninstalled the firewall.
Any light on this situation at all would be of great help.
