I just read the last seven pages and there seems to be unanimous consensus that the Hijack.DisplayProperties "infection" should be ignored. I'm using Windows 7 Home Premium and Microsoft Security Essentials. I noticed the internet going slow on my laptop, so I checked MSE and it had stopped auto-updating. It would not finish a manual update. The laptop was uploading (on its own) 1.3-2.2Mbps constantly. I downloaded and ran MBAM, removed Hijack.DisplayProperties and restarted. I ran no other cleaning software. Hijack.DisplayProperties was the only infection detected. Internet now completely normal again. Updated MSE finds no infections. How can this have happened if Hijack.DisplayProperties is a false positive and I had no other infections?
