Given what Spyhunter does on install I wonder if it's the cause. I can't know this but it's in the news.
For now, don't delete the account but disable it until you find the source. The clues alone here do not tell my what did it but Spyhunter is untrusted, in the news and more.

Although I can still logon normally to my laptop using Windows 7 I find that every time I check the list of user accounts under the Windows Control Panel, an unknown user account is somehow automatically created. The following are the details.

I have tried to delete this account and it just keeps showing up or somehow creates itself. I have performed several scans using ESET Smart Security 8 anti-virus software and Spyhunter 4 which had not detected any malicious virus related to this account.
Any help would be appreciated.
