Windows Support System is a rogue antispyware program which uses the name of Microsoft Windows and pretends to be a legitimate malware removal tool. The rogue from the family of fake Microsoft Security Essentials Alert malware that hides Windows desktop, disables legitimate antvirus applications, blocks Windows programs from running and displays fake security alerts in order to trick you into thinking your computer is infected. It hopes that you will next purchase so-called full version of the software. Do not pay for the bogus software! You should never trust in anything related to this application and remove Windows Support System from your computer as quickly as possible!
As all rogueware applications from same family, Windows Support System is distributed with the help of trojans. When the trojan is started, it will block important Windows applications (e.g. Task Manager, Internet Explorer, etc) from running and display false information that states “Unknown Win32/Trojan was detected on your computer”. The fake alert will prompt to perform a scan of your PC. Once the scan is complete, it will suggest to install WindowsSupport System to remove the trojan. If you confirm it by clicking to OK button, this malware will download and install Windows Emergency System and then restart your PC.
When Windows is loaded, you will be shown the Windows Support System prompt instead of Windows desktop. The fake antivirus will suggest to click “OK” button to start a system scan. After click to it, the rogue will perform a fake scan of your computer and list a lot of infections to trick you into thinking your PC in danger. It will report that was able to clean the majority of infected files, but was not able to cure a few important Windows files and offer to purchase its full version to clean them. However, the scan results is a scam, because the program is neither able to detect, nor to remove anything from your computer, especially viruses or other kind of malware. Thus, do not pay for the bogus software, simply ignore all that the fake antivirus will display you.
While Windows Support System is running, it will display display a variety of fake security warnings and block legitimate Windows applications on your computer. Some of the alerts are:
Attention
Suspicious software activity is detected.
Please start system files scanning for details.
Warning!
Name: taskmgr.exe
Name: C:\WINDOWS\taskmgr.exe
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.
Just like false scan results above, all of these alerts are a fake and supposed to scare you into thinking your computer is in danger. You should ignore all of them!
