I'm reformatting my rig and giving it a much better setup with drive partitions and so on. I was wondering what AV and Firewall everyone uses and if its even worth it. This is my "clean" computer and no garbage gets DL onto it. My only concern would be malicious emails. Now i have ZA and Norton installed... seems to be giving a big performance hit. I'm also running a router blocking incomming calls. Are these things needed to keep my system safe and if so what should I use?
