Now if you had some type infection, then I could see maybe running one to repair/replace files. Now it was a while back but it was enough to sell me on the fact, that I don't trust them in general. In other words, it was removing critical files. Testing on my end showed no improved speed (or was so low I could not tell) and in a couple cases where I got busy and did not checkup on the computer, when I did finally go back for more testing it started crashing. I don't know what all they remove, most only show the space that was freeded up and you could not see the actual files. Wiped the hard drive and did another clean install of a different Tuneup program and it pretty much did the same thing over a few days. The computer was never connected to the internet. I'm talking hundreds to at first was thousands.

Everyday it found some items to be removed.

I would let it run on it's own scheduled over a few days. I have tested doing 'PCTuneup' on a clean install of a windows computer. I am no fan of and do not trust ANY type PCTuneUp programs.
