Security Guard is a rogue antispyware application which promoted and installed through the use of trojans that usually come from fake online malware scanners. When you opens a page with this scanner, it simulates a system scan and once finished, tells you that your computer is infected with a lot of infections. Then offers to download and install an “antivirus”. The “antivirus” is a trojan, that once started, will download and install Security Guard onto your PC.
Once installed, Security Guard will configure itself to run automatically every time when your computer starts and create a lot of fake “infected” files. After this, the fake security program will start to scan your computer and mark the files that were created by the trojan-installer as viruses, worms, trojans and other malicious programs. Of course, the scan and its results are a fraud. The rogue uses the false scan results as method to trick you into purchase the full version of this program.
In addition to the above-described, Security Guard can block the Task Manager, and most antivirus and antispyware programs, as well as show a variety of false warnings and alerts. A few examples:
System alert

system and need to be dealt with immediately. Click here to
remove them using Security Guard.
System message
Your PC may still be infectd with dangerous viruses. Security
Guard protection is needed to prevent data loss and avoid
theft of your personal data and credit card details. Click here
to activate protection.
However, all of these alerts and warnings are fake and like scan false results should be ignored! Last but not least, Security Guard will add several lines into HOSTS file so that when you open Google, Yahoo or Bing, you will be redirected to a malicious website.
From the above, obviously, Security Guard is a scam which designed with one purpose to scare you into purchasing so-called “full” version of the program. Most important do not purchase it!
