misc.exe 'TR/Dropper.Gen' [trojan] gefunden

dr.beir

Hallo,

seit 2 Tagen ist mein Laptop extrem langsam und braucht ab und zu 20 minuten bis er hochgefahren ist. Antivir hat folgendes gefunden.

In der Datei 'C:\Windows\Installer\{90A40407-6000-11D3-8CFE-0150048383C9}\misc.exe'
wurde ein Virus oder unerwünschtes Programm 'TR/Dropper.Gen' [trojan] gefunden.
Ausgeführte Aktion: Zugriff verweigern

Habe danach noch mal einen Suchlauf durchführen lassen, allerdings wurde dabei nichts gefunden.
Weiterhin ist mir aufgefallen, dass einmal die windows firewall ausgeschaltet war, nachdem ich den laptop eingeschaltet hatte.
Firefox lässt sich außerdem auch nicht mehr öffnen. Der Pc hat kurze Phasen, in denen er ganz normal arbeitet, dann aber wieder extrem lange braucht.
Bin für jede Hilfe dankbar!
