Trojan DNS Codec Changer


Recommended Posts

Hi All,

I was redirected here by Maniac. I have got this horrible trojan, DNS Codec changer which is making my Firefox unstable and giving me pop ups. SuperAntoSpyware identified it as Trojan.DNS.Codec-changer but failed to get rid of it, as has Spy bot. Here are my logs from MBAM, Panda and HijackThis. Please help!
