Contrary to its name, defender.exe does not defend your computer from malicious attacks. Instead, it renders your computer even more vulnerable because it launches malware into the computer system. It is a fake security software that entices users to purchase the software by initializing several malware attacks that pop-up every time the computer is being used. It disguises itself as part of Microsoft’s system warning that alerts users when a virus or malware has been detected. The malicious software is presented under many names, changing every time the computer is opened and Windows is initialized. In most cases, the computer automatically shuts down after rebooting. It can cause the computer to completely crash. The malware is often hidden in advertising pop-ups that offer free malware scanning, and may also be introduced through unsafe downloading sites and lax browser security. Registry key for defender.exe is Data\.exeHKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run “defender.exe.” It may also be found in C:\Windows, C:\Windows Temp, and C:\Documents and Settings folders.
