I had problems with my computer, and I found the website www.ccleaner.com, which offered to download the cleaner software in order to remove all unnecessary things from the computer. This software didn’t work on my computer and didn’t remove bad things. I contacted the moderators, but they were really useless and couldn’t explain simple things to me. I was disappointed in their production and work. It might be a good idea, if people left their opinions about this website.
