Win32: Sirefef-PL [Rtk] problem

Viruses and worms
1

Hi I’ve been having a problem with Win32:Dnschanger warning popping up for a bit now, but none of the symptoms. After reading around I think the problem is Win32: Sirefef-PL [Rtk]. I’ve attached an aswMBR log. If someone could help me that would be great. Do you need anymore information?

you should also attach Malwarebytes and OTL logs

follow the guide here and attach (not copy and paste) logs from Malwarebytes / OTL / aswMBR
