Hi recently installed avast no probs at first but now when i start up i get error messages saying avast will not be able to protect incoming mail and outgoing mail with an error number 10022 Also when avast tries to check for updates i get cannot connect to server message although i can use the web perfectly fine Any suggestions?
Check the settings in Avast and make sure Avast has permission in your firewall.
Error 10022 means: An invalid argument was supplied (WSAEINVAL)
I hate numbered error messages 
But you can see more here: http://forum.avast.com/index.php?board=2;action=display;threadid=2760
Will this help?
