i have about 40 gigs left.
I always clean my drive, adware, or spyware. I have kaspersky anti virus, spybot search and destroy, windows advancecare pro and ccleaner.
My startup only loads up kaspersky.
I maintain my pc lik almost everytime i use it, which is everyday.
I just defragged it. And i do about every 2 weeks to a months.
Im not sure if i should use that washer program...i bet its like any other cleaner like the ones i have.
All they do is clean temporary files and all the other stuff.
On my msconfig all i have is kaspersky and ctfmon, i tried removing it but i think you have to use it and i doubt it barely does anything.
