Yeah, two anti-virus are most likely to collide...

Ha. My brother once had these tropical fish called "betas." They were beautiful, but you could only have one because they'd instantly go after a rival fish.

Yep. That's how two anti-virus programs act. They try to remove each other.

I'm getting rid of the 30-day trial of Trend Micro for now, and then I'm going to research virus protection software.
