dont knw if this is a bug or not but analyzing / cleaning the computer or scanning for issues take for more than 10 min ..
I'm having problems too. With the new 2.00.50, the progress bar refills several times and it takes about half a minute to 3 minutes complete. 1.42 would be finished in about 5 seconds, when the progress bar would fill up once. I thought this version was rewritten and optimized?
