Hi, I was having a similar problem and antimalware and Mcafee removed some things but the problem persisted. Someone suggested using Hitman Pro 3 from Cnet. I was to run it in safe mode but my computer would not do that so I ran it in regular mode. It found a file called "pciide.sys" which is normally a good file but must have been corrupted by malware. After Hitman Pro (free trial version) removed that file, I was able to get online normally again, no more redirects to advertising pages, WindowsUpdate began working again, my computer is running much more quietly, reboots go much faster, and I think more problems have been solved than I even realized I had. I hope this information can help anyone else with this problem.
