Up to 16 instances of dllhost.exe are started whenever an Internet connection is available. These all point to ad or other junk sites, example "http://blekko.com/ws/?=laptops+bad+credit+financing..." If I disconnect network cable, dllhost.exe instances drop one by one until after 10-15 minutes they are gone. As soon as I plug the network cable back in they start right up again. I have scanned with McAfee (found nothing), eset (found 2 threats and removed, but cannot load current signature files), and MBAM (found and removed around 30 threats). Currently eset and MBAM both report system is clean but this rogue behavior continues.
