Smart Security (SmartSecurity, Smart-Security) is a new fake Antivirus. It replaces Security Tool (Total security 2009 family).
Like the previous versions, registering the software won't help for updates. This tool is fake, during the download animation, there is no network activity. No files have been created when it says the tool is now Updated. The notable difference is: when registered, Smart Security does not detect malwares anymore (no cleaning required).
If your PC is infected with Smart Security use MBAM to remove the infection.
