Everyone else, well almost everyone else that cares, already knew this.
A search for
"Norton AntiVirus for OS/2"
with quotes, will get you some links, but probably no download links. You
might be able to find a legal copy on eBay or someone might have a copy
they are willing to sell you. You could ask on the os2world forum or the
os2warp mailing lists.
