I met up with that virus because a friend caught it from somewhere and I looked into it for him. Luckily he had done what I told him to do and that was to keep multiple backups. I was actually able to restore the hard drive intact, as it only deleted the beginning 100 sectors (thanks wikipedia). I immediately told a bunch of people I knew, and Eric G Corley who I also knew invited me to speak on his radio program "Off the Wall" on WUSB-FM. I was unable to make it because of prior commitments. From there on, there were a few variants of the idea. It taught me, and a lot of other people, not to boot from floppies that were not supposed to be booted from. I think shortly after that, I wrote a boot sector scanner that would scan the floppies when they were first inserted. art k. On 3/5/2019 6:34 PM, Dave Horsfall wrote:
