Malware antibytes is the answer?

Hello,

I have the security scan virus, though I haven't noticed any obvious problems yet in comparison to how it was working before I installed the thing - but I still of course want it gone. No pop ups or anything. However, I do have malware antibytes installed - since a technician installed it on my computer a few months when he was here fixing our internet connection for our laptops which got completely cut off from the desktop - which is where he installed - but it for some reason never could get the program to open, so what should I do??
