I had AntiVirus System Pro, b.exe, and msa.exe infecting my system. I removed them all by deleting the registry keys and program files. After they were deleted, I was still getting my search engine results redirected to other sites and firefox started crashing regularly. Also, as mentioned, Malware Bytes and Spybot randomly stopped working.
The message I get is "Windows can not access the specific device, path, or file. You may not have the appropriate permissions to access the item."
Here are the processes running:
