After being his with a virus several months ago, we where able to get the system back up and running without doing a fresh install. However, recently I went to install SEP and got the message that the BFE service was either not installed or not running. After further investigation, I realized it's not even listed as a service. The BFE.dll does exist and I've tried to execute a command live launch of it via "svchost.exe -k LocalServiceNoNetwork" but that does not seem to resolve the problem. Does anyone know of a solution other that OS reinstall?
