  • SACHOST.EXE? Schadelijk of niet??

    op mijn usb stick verschijnen de bestanden sachost.exe en autorun.inf telkens als ik hem in de pc stop. als ik de bestanden verwijder en de usb stick vervolgens weer in de pc stop staan ze er weer op.

    Inhoud autorun bestand:

    [AutoRun]
    open=sachost.exe
    shellexecute=sachost.exe
    shell\Auto\command=sachost.exe

    Op verschillende internetsites staat dat sachost.exe spyware of een trojan is.
    Mijn spywarescanners herkennen het echter niet.

    Nu is mijn vraag of sachost.exe schadelijk/ongewenst is, of dat het helpt om de usb stick te herkennen op de pc ofzo iets?

    Volg deze instructies om ComboFix te downloaden:
    • Voer de instructies op de BleepingComputer pagina uit, inclusief het installeren van de XP Recovery Console
      Indien je Combofix al eerder hebt gebruikt, gelieve die versie te verwijderen en Combofix opnieuw te downloaden via bovenstaande link, want Combofix wordt dagelijks geupdate.

      OPMERKING: indien je, tijdens of na het downloaden van Combofix of tijdens het gebruik van Combofix een melding krijgt van je Antivirus- of een andere realtime scanner,
      schakel dan deze scanner uit en download Combofix opnieuw.
      Sommige scanners zien bepaalde componenten die Combofix gebruikt als verdacht en gaan deze blokkeren of verwijderen!
      • Dubbelklik op Combofix.exe
        Tijdens het runnen van de fix, NIET in het venster klikken, want dit zal je pc doen vasthangen.
        Wanneer de fix voltooid is en na herstart, zal de log Combofix.txt openen.


      Plaats deze log in je volgende post, samen met een vers HijackThis logje.
    Groet,
    Pimmerd
