I can't even post I suppose I'm too tired but have HKEY-USER virus. S-2-5-21 is new user and admin on new computer. And 3 older locked computers

Will not even turn it on until I have answers to many questions.

Thanks for help but tired and will Be back later. Just got phone free from remote users using all my data and service on 3 days. Lived fine without going online. But this s-1-5-21 is no getting away from. Turned new comp off in March, and scared to for it was infected while setting up. 3rd computer same thing. Took 1st one back got it replaced and took that one back so this is 3rd Lenovo abroad. But they get infected with no msn account no wifi, in airplane mode. Can't understand. Made sure phone was off. I am tired but will return for any advice. For I have been up researching all night and not going to accomplish anything so tired. Thanks again for any advicr.
