I ran Rkill on a lenovo x220, then ran Combofix. I failed to see that the Lenovo Toolbox was open, which may have interfered somehow with Combofix. After Combofix finished, I then attempted to run the Malwarebytes Anti Malware, and received an error message stating "Illegal operation attempted on registry key that has been marked for deletion".
I cannot launch any programs, including a system restore. Any suggestions?
