You have probably downloaded malware. Check your PC with an antivirus scanner.
Control Panel → Programs and Features → Uninstall a program.
If that is not possible, optional;
Install CCleaner, go to the "Extras" tab on the left, then all programs will be listed. Right-click the program you want, then click Uninstall.
