My PC was becoming slower so I just google that how to make it faster. I found many websites were recommending to use CCleaner so I downloaded the trial version and installed it on my PC. I thought it will make my PC faster but when I run the scan it just deteced temperoray files and browser caches and deleted them but that can be deleted randomly. I was very much disappointed from the result. The biggest problem was that it used to delete my search history of all browser automatically.
There are many free software like Total 360 Security that clean the junks files as well as other unwanted junk things from PC so instead of buying CCleaner try it.
