USTechSupport.MyCleanPC is a fraudulent system registry cleaner. The EULA is displayed in a badly readable font. The EULA and privacy policy is marked to be accepted by default. After installation and after every reboot USTechSupport.MyCleanPC does a scan and shows thousands of entries which should be cleaned, the number includes fragmented disk space so the user is scared by the high number. Cleaning requires a paid registration while there is little to no user benefit.
