Interesting idea re: batch file .... don't know what commands I would use tho. Also, many AV products protect their processes; for example, running AVG, I used a utility I've got (DTask Manager) to send Kill signals to a process tree, but AVG just auto-restarted them on me. I have found a few more utilities that may be of use in this matter, but have not yet tested them.
The search goes on.
