|Yep, MalwareBytes is a good one. I usually get it from this website to be certain it is the free version (green icon at top right of page):|
You might care to run ADWCleaner too as sometimes you collect unwanted toolbars that can do some weird things. Get it here:
You Save the file somewhere (rather than running it) then double click the file. Run the Scan followed by the Clean and it will remove all bad toolbars.
Always pop back and let us know the outcome - thanks
