I just switched to avast! Home from AVG Free on my Windows XP Home SP-2 machine. So far, I like what I see - but the avast! WebShield process continually says that it is waiting for a subsystem to start. I also get periodic messages on startup that avast! can not protect my POP3, SMTP, NTP, etc.
I have my firewall (NetVeda Safety.Net) configured to give full access to all of the avast! executables, including WebShield. I temporarily switched to Kerio 4.1.3 to see if the problem was in the firewall software, but I still had the avast! problem with Kerio. I've also made sure that AVG Free was thoroughly uninstalled.
I've searched this forum for similar problems, but the posts I've found seem to apply to Win 9x systems, not XP.
I'm sure I'm missing something, but I can't pinpoint it. Any suggestions?
