I have a virus that is disguising itself as windows programs like winlogon.exe and csrss.exe, when I check the properties folder, there is another account holder with full permissions called trusted installer. Taken over control of Microsoft security essentials too.

Back up and rebuild, only real option.

Delete that account in user accounts in control panel

Then download and run malwarebytes and let it update itself and run full scan

Malwarebytes.org (http://www.malwarebytes.org/)

Let it remove whatever it finds and post back if still issues with files you mentioned above with as much info with any issues may be having
