If you didn't notice, SpyLocked has been renamed to Spyware Locked recently. This name change is easily explained. Spyware Locked is actually an updated variant of SpyLocked – some minor, mostly cosmetic changes have been introduced in order to avoid detection by legitimate spyware removers. The application is downloaded from the same web site as SpyLocked – www.spylocked.com. Don't go there!
The corrupt anti-spyware program these trojans distribute is yet another clone of the infamous VirusBurst and Spyware Quake risks.
