I've heard good things about Zone Alarm, 's true. However, that link doesn't mention anything about it being free, just that you can try it for 15 days before buying. Which I may well consider but I can't afford it right now. Hopefully, turning off the POP3 server option I mentioned in my reply to bibliogirl down there *points* will solve the problem for now :)

What's a "squared anti-malware" program when it's at home? Anti-malware I get but...squared? :)
