Yeah I’m having the Identical Problem too!! I’m running Win-XP Pro Svc PK3 using MS-Outlook as an email program. I tried to set up to send myself an email if an Avast message was generated. My ISP uses Encryption and SSL for their POP and SMTP connections on port 465. When I enter the SMTP information into AVAST and hit TEST - my PC goes Catatonic. It’s notable that there is no SELECTION to implement SSL encryption in the Avast email alert set-up. I suspect that is the source of the lock ups.
