Got a cybermaxx pc which had e-trust anti-virus software installed. The software has just expired (90 day limit) what software should i go with now. I have SP2 installed and have looked at prices on e bay for norton, mcafee, panda and e-trust. Should i go with E-trust again or should i pick one of the others or download AVG. Don't know if i will be better sticking with e-trust??
