Take Control of Your Privacy!

MyWinLocker utilizes advanced encryption technologies to easily password protect your files. Make sure no one knows the location of your private files by storing them in the invisible Yo-Safe. Furthermore, the self-decrypting feature enables you to freely share files with your friends!

Now, I just "Add & Remove Program"-ed it ... and ClamSentinel popped up a "C:\PROGRAM FILES (X86)\EGISTEC MYWINLOCKER\SHREDDER.EXE: PUA.Packed.PECompact-1 FOUND"

Otherwise it worked fine--yet requires a restart.

See, answering questions is fun.
