Dr. Guard is a rogue antispyware program, updated version of Paladin Antivirus, which is also rogue antispyware. The rogue is installed with the help of trojans. When the trojan is started, it will download and install Dr. Guard onto your computer without your permission and knowledge.
During installation, Dr. Guard will configure itself to run automatically when Windows loads and will ask you to uninstall legitimate antispyware tools (Malwarebytes’ Anti-Malware, AVG, etc), to protect itself from uninstalling. When installed and started, it will start an imitation of system scan and detect numerous infections that will not be fixed unless you first purchase the software. Nothing new here, this is a scam. Like other rogue antispyware applications, Dr. Guard is unable to detect or remove any infections. Important to know, all of these infections do not actually exist on your computer, so you can safely ignore the false scan results.
While Dr. Guard is running, you will be shown nag screens and fake security warnings from Windows task bar. A few samples:
Warning! Network attack detected!
Network intrusion detected!
Your computer is being attacked from a remote PC.
Your computer and all your personal data in serious danger.
Protection: Click the balloon to install antivirus software.
PLEASE, OPTIMIZE YOUR PC. IT RUNS ONLY 10%.
Warning! Keylogger detected!
Keylogger activity detected on your PC!
Warning! Virus threat detected!
Virus activity detected!
Nuker.Win16 adware has been detected
However, all of these warnings are fake and like false scan results should be ignored! As you can see, Dr. Guard is a scam, that created with one purpose to scare your into purchasing so-called “full” version of the program. Most importantly, do not purchase it!
