The problem is that the preview pane runs them automatically, If the
file has to be handled at any point such as unzipping a file (Many
windows users have no clue what a tar file is, and there's no reason
they should.) it usually breaks the chain. I believe MS started
defaulting to no executable by default a few viruses ago, with the
option to turn it back on, they need to turn it off and leave it off.
And stop hiding extensions.

They just had an anti-virus virus, which was at least as bad as the
original. Pass thanks.

Ehh, you might have given the morons time to back up essential work,
and seperated all the machines, verified they were clean, patched them.
And educated the users, before putting them back on line. It would have
eliminated the need to reinstall multiple times on the same machine, and
it needed to be done anyhow.
I hope your boss authorized it, preferably in writing, or they have a
sense of humor. Otherwise I'd start looking for a job outside the IT
