The real question is whether or not Kaspersky will let you exclude
specific processes from this sort of inspection.  If so, just exclude

I routinely have to do this depending on what AV I am running.  Heck,
if I run the whole Comodo Security Suite, I get pages of prompts every
time I run setup.exe and it changes files around.  It's all "hey, bash
is trusted, but it is doing something it didn't do yesterday and it
has a different checksum."

Security is pain.
