Let's assume you are the poor college student or simply someone that refuses to buy security software. Let's also assume that you are limited to using 4 security applications, what would they be? Presently, I am thinking that I would use the following (assuming they all play nice together): 1. Avira Antivir for AV 2. Comodo Firewall 3. Spyware Terminator for HIPS/antispyware 4. Sandboxie Overall, I would feel pretty comfortable with this suite. The firewall stealths all ports and passes all leak tests. The antivirus is not world class, but is good. The antispyware application has HIPS as well as other active guards that focus on prevention (though the scanner lacks in detection). And the sandbox should prevent a lot of stuff from getting on your machine anyway. As you can tell, I like to focus security on prevention.
