ongewenste popups ivm antivirusscherm en dergelijke

Daens

  • Hello

    Ik krijg op geregelde tijdstippen popups om valse antivirusprogramma's af te halen. Ik weet dat er al wat mensen problemen mee gehad hebben, maar met hun hijackfile kan ik weinig doen en blijkbaar werkt de link naar RVAXO (http://home.hetnet.nl/~stefsmeenk/RVAXO.exe) niet meer.
    Malwarebyte vindt dit, maar het keert telkens terug:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Settings\bf (Trojan.Agent)HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Settings\bk (Trojan.Agent) HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Settings\iu (Trojan.Agent) HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Settings\mu (Trojan.Agent)

    Vandaar mijn hijacklog, alvast bedankt:
