We've tried to warn ya about those pr0n sites          d:^)

Seriously tho, MBAM is an outstanding product .. did I mention it's also a freebie ?

I'd try FR with a different browser first (if you have one installed) to see if problem replicates.
Then d/l and run a scan w/MBAM to rule out nasties.

Different browser is way above my pay grade. My computer wont play with MBAM Wont let it download. Perhaps shut off trend micro for download?
