>> Another company I worked for had many customers (hospitals) and produced their latest upgrade. They bought the cheapest pre formatted floppies they could find and did not test them. The disks were sent out on a Friday, and the following Monday morning I loaded the new version on my test machine and found “Stealth 3 Virus”. Glad I was a consultant at that company – I was not afraid to alert the director of software. I confirmed the new floppies were the source of the virus. That is not nice!

>I was on the receiving end of that in like 89 or 90. Can't remember the company but as soon as I called they knew exactly what was the problem.

Happened to me too. What was worse was receiving Shrink Wrapped software which was infected with some virus or another. I also seem to recall a PC maker (for some reason Leading Edge comes to mind - but I'm not sure about that) which sent out infected setup disks.
