Hi, On a machine WinXPpro, outpost firewall(internal OS firewall disabled) is sometimes blocking my email client thunderbird with reason "blocked by process memory control" identifing that winlogon.exe is trying to write data into thunderbird. First I tought that I've got some spyware tryin to send some packets by smtp, but scaning with common antispyware programs didnt take any result. thunderbird have rules for an email client of course.
that any got some idea what is going on and how can I prevent it? Maybe some global rules that I cant reconize is responsible for that?
