Both problems solved.

When the upgrade to 13.1 happened, it cleared out the corrupted cache.
From now on I will be a lot more careful about the integrity of the
files I upload.
From now on I will test them out on my own system first to watch for
unusual behavior.
Just because the antivirus scan says that the file is ok doesn't
necessarily mean that it is.

As for the iso compression problem, I found out the hard way that nfs,
fuse, and zisofs
have to be included along with all the compression formats in order for
that to work.

Thanks
