CCleaner has been on my computers for over 10 years ... and I've had no problems with it. You just have to be careful what you ask the program to remove.

Malwarebytes has also been on my computer for almost as long, and it's a great program for removing malware. I also have SuperAntiSpyware, which I use to remove tracking cookies & other spyware programs.

I'm using the free versions of these programs ... and update/run them regularly.

My Antivirus program is the free version of Avast. And if you look at the most downloaded free programs listing on this C-net link ... Windows PC software downloads and reviews from CNET Download.com ... you'll find Avast, CCleaner, & Malwarebytes in the top 20 !!
