The other day i read someone who tried TuneUp Utilities.
Fixes many things but he said it didn't seem to make anything faster.
Personally, i did a scan with AVG AV a few days ago and it found a backdoor trojan belonging to TuneUp Utilities.
The program was rendered inoperative.
I wrote to AVG and to TuneUp, still no response with regards to test results or acknowledgment that there may be somekind of spyware...

CCleaner sure does remove alot!
-a bit late, but i remember AVG did respond and problem was solved.
