I'm just guessing...
How would they line up to do the multiple checks?
Wouldn't it go something like this:

A call to read a file, hooked into the AV instead.
AV scans, returns to the original destination of the read request.
Since there is no obvious way to send it off to do a second AV
scan, I think running two would be a problem.
Or they would at least have to be aware of each other and co-operate.
Or the OS could handle it, if they wanted to.

Besides, I think *everyone* has always said that was a bad idea.

yeah the idea here is that one program will catch something that another program may miss. Obviously it doesn't hurt to run them separately. But does it do any harm to run them at the same time? Will one stop another from checking a file?

It might, but I've never seen it.
