Additional Guard is a rogue antispyware program. It is a clone of Windows Additional Guard, which is also a fake antivirus program. Both programs are from the family of VirusDoctor scareware. It is distributed through malicious web sites that are disguised as online anti spyware scanners. It will stat that your computer is infected and you must install the software to clean your PC. The software is a trojan downloader. Once started, it will install the Additional Guard and create numerous files with random names in %UserProfile%\Recent folder. The files are made to appear as infections, but are in reality harmless.
Once running, Additional Guard will perform a scan of your computer and display false scan results. It will state that your computer is infected with adware, malware and trojans and that you should purchase the software to remove these infections. Of course, these infections are all fake, because Additional Guard identifies harmless files as dangerous infections. So you can safely ignore the scan results.
