There is very little assurance of anything.  I can give you my assurance that
my software does not contain any viruses, etc., when it leaves my possession.
But what if somebody fiddles with it before uploading it someplace?  It's up
to users to be very careful if they are not sure of the source.

If you are paranoid/careful, you will test newly-downloaded software on a
scratch disk, with no other disks online & with any hard drives turned OFF.
When finished testing the new software, you will do a power-down reboot of
the system.

This sort of "being careful" could be a real pain for battery-backed RAMdisk
users.

Users with the appropriate skills & plenty of time to waste can examine the
program for suspicious looking things.  The trouble is that anybody clever
and deranged enough to put nastiness into a piece of software is NOT going to
be stupid enough to make it obvious.

CompuServe--There is a 1 or 2 day delay on CompuServe (or in the APPLE forums,
at least) between when someone uploads something & when it becomes available
for downloading.  I *hope* that one of the Sysops is taking that time to try
out the program look for nasty stuff. -- I will ask.

Except for commercial software, where it is unlikely for a virus or
Trojan horse and where I have obvious legal recourse if one turns up,
I simply don't run any imported binaries.  I insist on source code,
and I check it to make sure I understand it and that there are no
mystery features that might cause problems.  This may seem overkill,
but when there are too many assholes in the world, one has to take
pains to protect oneself and one's property.

Let the buyer (or hacker?) beware!

This is the *only* way to go in the IBM world!  And not a bad idea *at all*
for us.

Another reason why people really ought to use hard disks with intellegent
disk caching! :-)

However, the majority of "viruses" are undetectable, by there vary nature.
Most of the "reformatting hard disk, sucker!" ones are not very well hidden
at all, and thus it's a good idea to scan the disk file with a disk editor
to look for such messages. . .

Many realiable BBS's do indeed do just that, but some cannot, for it would
mean going offline for every test.

Hay, Dave;s a great guy, went to highschool with him, and worked with him
after I graduated.  Buy his stuff!  He's a good tech support person also!
