What is People PC (is it webmail viewed using your browser or normal smtp/pop3 email client) ?
What is your firewall ?
Does it allow ashMaiSv.exe (pop3 email scanner) ashWebSv.exe (web shield that would scan webmail you view through your browser) internet access ?
- If it does delete the entries for them and do a manual update and reconnect to the internet, this will force the firewall to ask permission again.
