Trojaner-Board - Infiziert

Seit ein paar Tagen hat mein Rechner extrem hohe prozessorauslastungen, obwohl von meiner Seite aus keine Anwendung läuft oder ähnliches.

Habe in Der Autostart von Windows zwei gleiche Einträge:

Registry\HKLM\Run C:\WINDOWS\system32\smsss.exe
Registry\HKCU\Run C:\WINDOWS\system32\smsss.exe
