I just had this EXACT same thing happen to me as well, as a result of today's MWB Premium scan.
thisisu: So, ... are you guys going to fix this or what? You did not respond to that part of asianmusicguy's post. I always intended to ignore it, but I have to agree with asianmusicguy, it should not happen in the first place! Process Explorer is a Microsoft Product, and its Task Manager version is miles better than the one that comes with Windows. Beyond that however, is the fact that the Process Explorer version does not install itself alongside the original version - it REPLACES it! A less knowledgeable user might take MWB at its word and click the 'big red X in the circle' and completely disable ANY Task Manager capability in the system. That would be a HUGE problem when the time comes that it is really needed.
I think malware-flagging any product published by the very same developer as the operating system that MWB itself operates within, should be a really BIG no-no, don't you?
