How to Remove PC Cleaner Popups

Updated September 28, 2017

PC Cleaner is a spyware that disguises itself as a legitimate anti-virus and infects computers through trojan viruses. This application will generate multiple pop-ups showing viruses and other threats found on your computer. Then it will offer you an opportunity to buy the PC Cleaner application to remove the found parasites. However, paying for this software will not do a thing for your computer, as the messages are fake, and PC Cleaner itself is the spyware. You will need to stop the spyware from running in the background, unregister its DLL and remove registry keys and files created by this program. The pop-ups will be gone once the spyware is erased.
