CleanUp Antivirus is a new fake Antivirus. This rogue drops files on the system and detects them as infected to scare users; files are filled with junk data and do not represent a risk. It replaces Security Antivirus and My Security Wall (family link)
CleanUp Antivirus comes from fake online scanners.
If your PC is infected with CleanUp Antivirus use MBAM to remove the infection.
