I'm trying out Windows 7 on a new build with an Asrock mobo and a Celeron Dual processor. I'm very paranoid about viruses and malware, and am asking for recommendations for free, good antivirus, antispyware and firewall for my machine. On my present, years old WinXP desktop (no Vista for me,thank you), I get good results with Avira, Superantispyware and ZoneAlarm firewall. Do they have versions good for Win7?
