System Security 2011

Also Known As: System Security 2011 Rogue
Damage level: High

What is System Security 2011?

System Security 2011 is a fake computer security scanner that attempts to trick computer users into purchasing a fake license. This bogus program is derived from the same family of rogue scanners as Cloud Protection, Guard Online, and many others.

Like its previous version, System Security 2011 is proliferated through misleading websites that exploit various security vulnerabilities in users' PCs to install rogue programs. This fake computer scanner is installed on your computer along with a rootkit infection that makes System Security 2011 harder to remove.

The rootkit blocks legitimate security scanners that try to scan your computer. To remove this bogus scanner, you need to eliminate the rootkit infection first.

When infected with System Security 2011, a security scan is performed each time you boot your operating system and your desktop will be flooded with various security warning alerts.

Ignore these scans and pop-up messages, they are fake. System Security 2011 imitates the security scans, which are performed to scare you into believing that your computer has serious security issues.

Internet criminals hope that you will purchase a fake license for this program. Ignore the messages displayed by System Security 2011 and remove it from your computer immediately.

The security issues 'detected' by this bogus program, do not exist - this is simply a misleading strategy used by Internet criminals who create fake security scanners. This program has the appearance of an antivirus program, but it does posses any of the functionality required of legitimate security software and has no capability to detect security infections on your PC.

System Security 2011 is malicious software and you should not hesitate in eliminating it from your computer.

The following fake pop-up messages will be displayed on a computer infected with System Security 2011:

"Security Warning. Malicious programs that may steal your private information and prevent your system from working properly are detected on your computer. Click here to clean your PC immediately."

"Warning! The file "taskmgr.exe" is infected. Running of application is impossible. Please activate your antivirus software."

"Windows Security Alert. To help protect your computer, Windows Firewall has blocked some features of this program. Do you want to keep blocking this program? Name: Zeus Trojan Publisher: Unauthorized."

"Warning! Infection found. Unwanted software (malware) or tracking cookies have been found during last scan. It is highly recommended to remove it from your computer. Keylogger Zeus was detected and put in quarantine. Keylogger Zeus is a very dangerous software used by criminals to steal personal data such as credit card information, access to banking accounts, passwords to social networks and e-mails."

These security warnings are fake. If you notice that your computer is infected with System Security 2011, you should remove it immediately.

Summary:

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 fake antivirus 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.
