  1. Dear Patrik,
    I have the wdmaud.sys trojan, and I’d really appreciate your help.
    (1. above, the link to OTmoveIt3 does not work)
    2. for me, MBAM does not find the associated malware. It says that my computer is clean.
    Should I use the forum? Thanks in advance.

  3. Hi, I followed all the instructions on here but I still have those files and I’m still getting redirected to junk sites. When I restarted my computer, all of a sudden there was another wdmaud in my systems32 folder. Both are at 23 kb. Malwarebytes did not show any infected results.
