There seem to be several variations of infections going around that are damaging the Windows service Base Filtering Engine. The infection is easy enough to remove. The variation on my machine is "Win 7 Internet Security 2012", essentially a garbage file created in %appdata%, hidden there, and linked through the run/open command in the registry. I was following a thread here at: http://forums.majorgeeks.com/showthread.php?t=249071 in which admin chaslang seems to have corrected a similar issue (though doing it on TeamView and not posting resolution steps). At this point, I've gotten the service back, dll is in place, but the service will not start (error 5: access is denied). If it's not too much trouble, what follow up steps am I missing? The BFE service is now in place after removing the infection with various tools. The unit gets online fine now and after following the prior chaslang thread with user EStrother I now have the BFE service back where it belongs and it's dependencies no longer alert me that BFE is missing. The service is set to auto start, but it won't start, when I run services.msc to start it, it tries to and crashes to the previous error 5 issue. What's going on? Thanks in advance for any help.
