I had adware removed and a frozen popup in the middle of my screen removed by Mcafee Techmaster. It took a little over an hour to get it straightened out. I tried uninstalling the application myself but it wouldn't work. Anyway I'm back in business thankfully. Thanks for your response! I believe the problem was with Multiplicity, It's gone now. My screen is back to normal.

It is unlikely Multiplicity was to blame for this. I suspect it was the adware you had removed which was the problem.
Multiplicity will only show a popup when it expires and it wouldn't stop anything else loading.
