I have a very similar situation. I get 'requested resource is in use' and when I try to open Task Manager it just flashes open for a second and then closes. The BIG problem is that I can not open any of the virus and/or malware programs I had installed; nor any progra,s I download and try to open. This includes any from your company.
I read this thread and tried all suggested steps.
I attempted googling for suggestions. All main google listings lead with your company offerings.
As you must know, this is a fairly recent problem and has already hit 100's & 100's of computer users.
I hope that you can help me and the others as it occurs.
Thanks
Jerry
