Onscreen fonts changed after installing driver update and breach guard

Just purchased and installed Driver Update and Breach Guard.  Within a few minutes, monitor went black and computer wouldn't work.  Unplugged then plugged back in and everything works now.  Problem is that all of my onscreen fonts are now HUGE. Why would that happen and how do I get them back to normal?  Thanks!
