What is Windows Security System?
Windows Security System is malicious software, which imitates a legitimate antivirus program. In fact, this bogus software has none of the features required of an antivirus program - it is merely a scam released by Internet criminals. They designed Windows Security System to imitate the processes of a computer security scanner and to scare unsuspecting PC users into believing that their computers have various malware and virus infections. To distribute this fake program, Internet criminals use Trojan infections, which infiltrate users' computers and install this rogue software without permission.
These Trojans serve as downloaders, which can spread various types of infections from key-loggers to fake antivirus programs such as Windows Security System. The Trojans used to proliferate this scam are distributed via spam campaigns, P2P networks, and various misleading websites. To keep your PC clean from such infections, update your operating system and use legitimate anti-spyware and antivirus programs. After infecting your PC, this misleading program modifies your operating system and configures itself to start on each system start-up. Furthermore, it generates various random files in your Windows temporary files folder. Windows Security System 'detects' these newly-created random files as malware - all part of its fake security check-up. It then advises PC users to 'convert to a full version' (i.e. purchase a license for Windows Security System) in order to remove them.
This program is not unique, and is derived from a family of similar rogues whose distribution dates back to 2011. Predecessors of Windows Security System were named Antivirus Protection 2012 and Security Monitor 2012. Do not trust any information displayed by this rogue software, since its main goal is to trick you into purchasing a useless license key. If you click 'Clean and Disinfect' after the fake security scan displayed by Windows Security System, you will be asked to purchase this program to clean the 'detected' security infections. Do not buy this program, it is a scam. Security threats supposedly found by this program do not exist on your computer. Use this removal guide to help eliminate this scam from your PC.

After saving the file to your desktop, double click it. In the main HijackThis window click the “Do a system scan only” button. Select the following entries (place a tick at the left of the entries):
O4 - HKCU\..\Run: [Security Manager] C:\Documents and Settings\[User Name]\Application Data\Windows Security System\windowssecuritysystem.exe
O4 - HKCU\..\Run: [Windows Security System] "C:\Documents and Settings\[User Name]\Application Data\Windows Security System\windowssecuritysystem.exe" /STARTUP
After selecting the required entries, click "Fix Checked". After this procedure, close HijackThis and proceed to the next removal step.
4. Download and install antispyware software to completely remove the infection.
Other tools known to remove Windows Security System:
The fake antivirus programs (also known as "rogue antivirus programs" or "scareware") are applications that tries to lure computer users into paying for their non-existent full versions to remove the supposedly detected security infections (although the computer is actually clean). These bogus programs are created by cyber criminals who design them to look as legitimate antivirus software. Most commonly rogue antivirus programs infiltrate user's computer using poop-up windows or alerts which appear when users surf the Internet. These deceptive messages trick users into downloading a rogue antivirus program on their computers. Other known tactics used to spread scareware include exploit kits, infected email messages, online ad networks, drive-by downloads, or even direct calls to user's offering free support.
A computer that is infected with a fake antivirus program might also have other malware installed on it as rogue antivirus programs often are bundled with Trojans and exploit kits. Noteworthy that additional malware that infiltrates user's operating system remains on victim's computer regardless of whether a payment for a non-existent full version of a fake antivirus program is made. Here are some examples of fake security warning messages that are used in Windows Security System distribution:
Computer users who are dealing with a rogue security software shouldn't buy it's full version. By paying for a license key of a fake antivirus program users would send their money and banking information to cyber criminals. Users who have already entered their credit card number (or other sensitive information) when asked by such bogus software should inform their credit card company that they have been tricked into buying a rogue security software.

To protect your computer from Windows Security System and other rogue antivirus programs users should:
- Keep their operating system and all of the installed programs up-to-date.
- Use legitimate antivirus and anti-spyware programs.
- Use caution when clicking on links in social networking websites and email messages.
- Don't trust online pop-up messages which state that your computer is infected and offers you to download security software.
Symptoms indicating that your operating system is infected with a fake antivirus program:
- Intrusive security warning pop-up messages.
- Alerts asking to upgrade to a paid version of a program to remove the supposedly detected malware.
- Slow computer performance.
- Disabled Windows updates.
- Blocked Task Manager.
