Hey paperclipman! Microsoft Security Essentials is a good free option if you want decent protection. But since you're in college, I'm sure your school offers a free copy of one of the "enterprise" level anti-virus solutions. My university offers Symantec Endpoint to all of it's faculty/staff/students. So you should definitely check out your schools IT Support website to see if they offer anything. I mean you are sorta paying for it:P
I was also surprised by the fact that my G2 did not have it. But I'm still on 2.2.1; waiting for the OTA upgrade to 2.3.4. Are you running the latest version?
