my AVG has become corrupt and a virus has slipped through. No idea where it's hiding or what it is called.
But whenever I open an explorer window containing an anti virus program, the window is shut down before I can double click on the setup.
My AVG won't re-install in Safe Mode.
Does anyone know of an anti virus program that can be installed from DOS?
Or can I rename my AVG installler something like Fred.EXE and fool the damn virus?
Any suggestions welcome

   That sounds like one of the features of Windows called Data Execution Prevention.  It is not neccessarily a virus.  Running video files can cause Windows to do that.
   You can disable that feature in the boot.ini file.  There is a post about it in this board at http://www.regvac.com/forum/b-answin/m-1138631069/  My last post in that thread tells the solution.

OK I get the drift.
I've printed out the solution and will give it a try.
Thanks for that - I was really stuck.

   No, I was serious when I called it a feature.  It is a feature (not necessarily a good one) of Windows.
   As I remember it, at first it disabled me from playing certain videos (these were perfectly good videos with nothing wrong with them) and when I continued to try and play the videos, Windows Explorer shut down whenever I tried to even access the folder that the videos were in.  It is a real hassle.
   Disabling it is simple.

The last time I came across this "feature" I wiped the hard drive so this is a much simpler solution.
Thanks very much
