SpyLocked is the latest rogue anti-spyware program to come out from the makers of SpyDawn and Virusburst. SpyLocked is installed by a trojan called Zlob, which attempts to trick you into buying the alleged anti-spyware program. Once you're infected with SpyLocked, a fake security message similar to a Windows notification pops up saying your PC is infected with malware. This SpyLocked message is used to lure you into purchasing, downloading and installing their program to remove the imaginary spyware.

SpyLocked may also automatically launch at your computer's startup and scan your computer. SpyLocked can be extremely difficult to remove manually, and will continue to try to recreate itself.

This will remove it, free.
