Problems caused by STOPzilla and it’s very much troublesome.

I use STOPzilla and it works well.
But yesterday it was acting very funky.
Running slowly,wouldn't open program,outlook is not opening, had difficulty getting online etc are happening.
I have a live chat with STOPzilla.
They advised me to uninstall. After uninstalling the computer quit responding.
I have tried restore system, start in safe mood but failed. How to solve the problem?
