I tried a couple of those "cleaner" utilities in the past. They wiped stuff that was needed, and didn't improve the performance of the PC one jot. I steer clear of them nowadays.
One that crept in under cover of a software update (beware of Adobe!) recently told me there were over 500 dangerous items on my PC, and that for $30 they would fix it for me. They made the mistake of listing the first 20 offending items.
Fortunately, the control panel "remove software" worked with the $30 freebie. I'm close to dumping Adobe!
