TheRegistrySentinel
The Registry Sentinel, also known as TheRegistrySentinel, is a rogue registry cleaner. TheRegistrySentinel is designed to identify and fix registry errors, but instead it displays false positives to trick the user into believing there's a malware infection. The Registry Sentinel comes bundled with another rogue anti-spyware program called The Web Sentinel, which together they form a group of anti-spyware program that is under the name Your Web Safe.
Once you're infected with either of the rogue anti-spyware programs (TheRegistrySentinel, The Web Sentinel or Your Web Safe), it installs the Locker.exe file on the user's computer which displays a purchase window that will not close until the user purchases the program. The Locker.exe file disables typical keyboard commands like Alt+Tab, Ctrl+Alt+Delete, and others. The only way you can remove TheRegistrySentinel, along with The Web Sentinel and Your Web Safe, is by pressing Ctrl+N to open a new browser window and begin a scan with an antivirus or anti-spyware program to clean the computer. If you download The Registry Sentinel, it will start a scan that displays false positives on your computer. It is strongly recommended to remove The Registry Sentinel from your system without any hesitation.
