I just got a new computer uploaded with Norton and a free year of CA Internet Security. I have deleted Norton from the computer due to it's incessant ads and I have not even opened up the CA Security box.
I recommend: Spybot for malware and spyware, Malware Bytes, and Avira Antivir. All free.
As for firewall, I don't know as my wireless network and computer are both password protected. I have the standard Windows 7 firewall turned on.
What is the status on AVG Free nowadays? Is it still buggy where it is not updating? I loved AVG Free until AVG 8.0 where it mucked everything up and all updates had to be done manually at their website.
