Ta bort Windows Functionality Checker

Wednesday, February 22nd 2012 under Security by

Windows Functionality Checker is a fake anti-virus program, successor to the rogues Home Safety Essentials and Windows Protection Master. Since the three of them belong to the same rogue family, they use similar techniques for infecting and taking over the targeted machines. Malicious advertising strategies are something usual for such pieces of malware, and they are not missing here, as well.

Hacked websites serve as a platform for transmitting the Windows Functionality Checker infection. The rogue uses the help of Trojans, laid in the compromised websites, in order to sneak into a machine. Those Trojans are triggered if the victim clicks through the website – one click is enough for them to creep into the computer system through vulnerabilities found in it. Such vulnerabilities are mainly present due to outdated software. Therefor, it is highly recommended to keep all your programs up-to-date. What is more, it is highly advisable to download the updates only from the official websites of the products – files, downloaded from shady webpages may be bundled with viruses. Another efficient prevention strategy is to keep away from suspicious websites and run regular scans of your PC with a legitimate anti-virus vendor.

As soon as the Trojans get inside the system, they immediately install the rogue – Windows Functionality Checker. Upon its installations, Windows Functionality Checker makes malicious configurations, which enable it to start automatically. Then, Windows Functionality Checker starts producing a variety of phony alerts and notifications, warnings about non-existing security problems and potential security threats. You can see some examples of such bogus pop-ups is below:

Keylogger activity detected. System information security is at risk.
It is recommended to activate protection and run a full system scan.

Software without a digital signature detected.
Your system files are at risk. We strongly advise you to activate your protection.

Potential malware detected.
It is recommended to activate protection and perform a thorough system scan to remove the malware.

Warning! Virus Detected
Threat detected: FTP Server
Infected file: C:\Windows\System32\dllcache\wmploc.dll

These alerts are not only irritating – they slow down the PC’s overall performance. Their main purpose is to make the user believe there is a great security risk. Clicking on any of them only prompts the victim to purchase Windows Functionality Checker.

The next step of Windows Functionality Checker’s malicious plan is its bogus scanning tool – it starts every time and again and pretends to be scanning the system for viruses. The truth is, it is not capable of detecting or removing threats – it only aims at scaring the victim into believing he/she needs to purchase the full version of Windows Functionality Checker. In reality, however, the full version of Windows Functionality Checker is just as inefficient when it comes to coping with viruses, as the trial one. They are both part of a great scam, created by hackers in order to gain profit by unsuspecting users. The infections, reported after each scan, are not real. Indeed, cyber criminals have invented a very crafty interface that might mislead unaware users. The layout even includes a section, which classifies the different “alert levels”. No matter how Windows Functionality Checker tries to convince you in its legitimacy, however, you should not believe any of its alerts.
