I want to get rid of McAfee replacing it with a lower resource demand software, but I need to choose wise three things: For Antivirus I'm trying AVG on one computer and Avast it the other, I think they are good, I'm gonna test them and see which one performs better. Firewall I don' really know if the one with XP is enough, I guess not, but don't know much about other firewalls, I'm gonna try zone alarm. I've heard it's a good one. Where I have no idea and I need suggestion is with Antispyware/adware/malware please let me know what do you use. Thank you!
