Windows Concern System

As a rogue security program that reuses most of Windows Concern System's appearance and code from similar threats, Windows Concern System attempts to mislead you into trusting Windows Concern System by using fake anti-virus features. Windows Concern System will create fake infection warnings and other system alerts with dishonest content, as well as hijack your web browser and block programs to make your PC appear more damaged than it really is. Instead of purchasing a Windows Concern System license to make these attacks stop, it's strongly recommended for you to remove Windows Concern System with the help of an anti-malware scanner.

Windows Concern System – Another Fake Security Application Straight from the Assembly Line

Windows Concern System is related to other rogue security programs in a large family of threats that share a basic appearance as well as malicious code. Closely-related threats include Windows Salvage System, Windows Oversight Center, Windows Necessary Firewall, Windows Risks Preventionsand Windows Custom Settings.

Windows Concern System and related threats are often installed with the help of a Fake Microsoft Security Essentials Alert Trojan. Just as the name would lead you to expect, Fake Microsoft Security Essentials Alert uses pop-ups like the following, to imitate a Security Essentials Alert window while it installs Windows Concern System:

To remove the malware please run a full system scan. Press 'OK' to install the software necessary to initiate system files check. To complete the installation process please reboot your computer.

You may also become infected with Windows Concern System after visiting a malicious website that uses drive-by download scripts. To protect yourself from such scripts use the latest updates for your web browser and security software, as well as disabling Flash and Java for websites that you don't trust. Windows Concern System is a very new threat as of June 2011, and may avoid being detected by less-updated scanners.

Windows Concern System's Cookie Cutter Assault Technique

Windows Concern System exhibits the same behavior that Windows Concern System's clones use, partially to disable your PC security, and partially to fake an appearance of being a security program itself. Windows Concern System's most well-known attacks include:

• Windows Concern System may block programs with or without the use of error messages such as the samples seen below. These errors don't indicate that your programs are really infected; once removing Windows Concern System, all 'infected' applications should resume normal behavior.

  Warning!
  Location: [application file path]
  Viruses: Backdoor.Win32.Rbot

  Warning!
  Name: [application file name]
  Name: [application file path]
  Application that seems to be a key-logger is detected. System information security is at risk. It is recommended to enable the security mode and run total System scanning.

• Windows Concern System may also create general system warnings that are similarly false. Stay alert for pop-up-related attempts to redirect you to malicious websites like the Windows Concern System homepage.

• Although pop-up-based browser redirections are possible, more often, Windows Concern System website-based attacks will occur in the form of browser-hijacking efforts. Browser hijacks are accomplished by altering the Windows Registry to enable the infection to control the browser through the use of extra privileges, or by changing proxy server settings. Browser hijacks by Windows Concern System, can create fake error pages, block websites and redirect you to dangerous sites.

Windows Concern System's main goal is to steal your credit card number by forcing you to purchase Windows Concern System for these problems to cease. Nonetheless, since Windows Concern System has no virus detection or removal functions, and causes significant security problems for your PC, removing Windows Concern System is the recommended action.

Using anti-virus software in Safe Mode with administrator privileges is the safest way to remove Windows Concern System. Attempting to delete Windows Concern System manually may cause other problems for your computer, like disabled Internet connectivity.
