Best free anti-virus is (in my opinion) AVG (I think its only one which is free). and in opensource anti-virus best would have to be Clamwin

More on clamwin at http://sourceforge.net/projects/clamwin/

And yes no offence but

How is it possible that a teacher who poses threat to security of the network of the school, who doesnt teach their students the fundamental's of virii but tell them to infect every computer with all possible malware just to see which is the best antivirus (that also free). This is then coupled with students who are out searching for virii and other malware (on site's where most of the members are social-eng free) and dont know what is a firewall and call it crazy firewall....... going to protect a network or test a anti-virus. Are you sure you are doing a Security A+ ?
