System Check virus

What is System Check?

System Check is a misleading program that hides desktop icons and start menu items in order to scare computer users in believing that their computer hardware has malfunctioned. The program differs from typical fake antivirus software, since it employs different tactics to scare computer users.

While a typical rogue anti-spyware program scans your computer for security threats and then displays a fake detection list, System Check mimics a scan of your hard drive and then generates fake warning messages reporting that your computer hardware has malfunctioned and you could potentially lose your data. System Check is a fake computer program.

This rogue scanner is a copy of previous versions: System Fix, Data Restore, System Recovery, and many others.

When installed on your computer 'System Check' generates the following fake security warning messages:

"Critical Error Hard drive clusters are partly damaged. Segment load failure."

"System Check will scan the system to identify performance problems. Start or Cancel."

"Critical Error. RAM memory usage is critically high. RAM memory failure."

"Critical Error Windows can't find hard disk space. Hard drive error."

"Activation Reminder. System Check. Advanced module activation required to fix detected errors and performance issues. Please purchase Advanced Module license to activate this software and enable all features."

Like previous versions, System Check is proliferated via various misleading methods. Internet criminals distribute bogus scanners such as this using Trojans, and when infected with System Check, you will notice many system warning pop-ups reporting that your computer hardware has malfunctioned.

The main window of this program will appear on your desktop each time you boot your PC. This fake computer scanner modifies the registry of infected computer operating systems, thus enabling System Check to disable various Windows functions.

To further scare you into believing that your hard drive has serious problems, System Check hides your desktop icons. Despite this, you should not panic, since this bogus scanner simply hides them.

These processes are performed with one intention - to sell you a license key for a useless program. The computer scans are fake, and there are likely to be no problems with the hardware on your PC. This fake computer optimizer merely attempts to scare you into believing that you could lose your data.

Do not buy the license for System Check; it is a fake program, which should be removed from your computer immediately. System Check has nothing in common with genuine computer registry fixers, and you will not find any legitimate functions required of such software.

Do not be intimidated by the warning message pop-ups displayed by System Check - the reports of serious hardware failures are false. The 'defragmentation' and other features displayed by this bogus program are also fake.

If you have already bought a license for this fake program, do not hesitate to contact your credit card company to demand a refund. Follow this removal guide to completely remove System Check from your computer and regain control of your hidden data.

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. Screenshot of a web page used to lure computer users into paying for a non-existent full version of system check rogue and other rogue antivirus programs:

To protect your computer from system check rogue 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.

• 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.
