My hard drive crashed on my Intel iMac. I am running Windows XP in Apple's Boot Camp. I received an offer in my e-mail for a free upgrade to ESET Smart Security 4.2. I don't need the firewall or the anti-spam. I use a router along with the Windows XP built-in firewall. Can I just upgrade to Nod 32 Antivirus 4? I guess I could turn the firewall and the anti-Spam filter off. Moderators, if it posts it in the wrong forum please feel free to move. ETA: I was using Nod32 antivirus version 3, so the builds are different. Right now I have no antivirus on my Windows machine. I need to start reinstalling all my programs. I did not lose any data. Thanks.
