Anti Virus Software for School Computers

My college scholarship did not cover a personal computer or laptop. As a result, I spend a great deal of time in the computer lab on campus. I figured a major school like this would have fancy antivirus software. So I was very surprised to see that they use avg download. That is the same program my dad uses at home. He pays less than three dollars a month for this software and loves it. Apparently this school does too because, according to the guy who runs the computer lab, that is the only program used on school computers. When I do get my own personal computer, I plan on using this program also.
