I finally came here......I should have come here first...... .......only to see that I could have protected my pc for free.
I am going to try and get a refund.....and uninstall it......because it hasn't worked right since installing.....
Anyway....I have been having the same problems as others here......lag in programs opening........not being able to open control panel, etc.
Soooo....I am going to follow the procedure listed. I'll let you know how it goes!
