Mystery User Account Created on Boot?

Hello, I have a brand new dell laptop with Win 7 Home Premium. I recently bought a better harddrive for it and cloned the disk from the old one to the new, and the process worked fine without any issues. I booted into the new hdd, and everything appeared to be okay. But now theres this strange user account that keeps getting created every time I cold boot the system. I can delete it and it remains gone until the next cold boot (restarting however doesn't create the profile). The profile is empty and has to be "prepared" if I click it.



this is the account it makes, it doesn't appear to be created by a program that I can find. It doesn't seem to be a malicious software issue either. Maybe the clone did something to the registry? Looking for some help, haven't had any luck with google searching this issue.

Ah just found out the cause... so it ended up being something I changed related to security software I own. Should have known. I changed the rights to a special user account that the software creates and it didn't like it, so I randomly generated this mystery account.
