Smart Security 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 My Security Shield, Security Master AV, My Security Engine, Security Guard, CleanUp Antivirus and Security Antivirus (family link)
Smart Security name was already used by a previous rogue:
Smart Security comes from fake online scanners and porn sites
If your PC is infected with Smart Security use MBAM to remove the infection.
