Can anyone tell me if the free perfromance scan they offer on here safe to use?

well its like when I cam to this thread at the top and bottom of the thread it said reccomended fix click here to run a free scan to fix your vista errors. this is the site it gives you when you click the link Registry — RegistryBooster — Top Rated Registry Cleaner. it saids microsoft gold certified.

If you want a very similar program try glary utlities.

try pcpitstop.com

My advice? You shouldn't use any 'performance scans' found online.

Go check out the free software thread Brink has (in the software section of course) and try some of the more reputable tune-up programs.

I personally don't like the all in one utilities very much, so I stick to smaller programs for individual tasks (ex. CCleaner, Malwarebytes', built in disk cleanup etc...).
