These two executable files are showing up in my roaming folder, as well as on the list of startup programs. A Google search hasn't yielded any results. Should I be worried?
It's not a good sign and I would try disabling their startup with Autoruns, and/or run a scan with Malwarebytes Antimalware(free version).
Ok, so after a scan, E6B9 is gone, but according to the startup list, Cjsasc still remains.
