Hallo an alle, ich verzweifel langsam.
Hab seit ca. 3 Tagen mit dem svchost.exe Virus, der immer wieder im Windows\temp auftaucht. Denke ich hab den erfolgreich gelöscht, aber nun bekomme ich beim anmelden nur noch einen schwarzen Bildschirm.
Ein Hijack Log ist hier:

Hallo und

Bitte diese Liste beachten und abarbeiten. Beim Scan mit MalwareBytes auch alle externen Speicher (ext. Platten, USB-Sticks, ... mit anklemmen!! )

Wichtig für Benutzer mit Windows Vista und Windows 7: Bitte alle Tools per Rechtsklick => Als Admin ausführen!

Die Logfiles kannst Du zB alle in eine Datei zippen und auf File-Upload.net hochladen und hier verlinken, denn 1. sind manche Logfiles fürs Board nämlich zu groß und 2. kann ich mit einem Klick mir gleich alle auf einmal runterladen.
