This is a sketchy >idea, true, but I thought I'd ask it anyway. It is much easier to simply run the suspect code on a system without a hard disk. That is what I did when I downloaded PK36.EXE, the latest version of PKARC, from SIMTEL20. We have a PC-Convertible that has only two diskettes, no hard disk. I suppose this is an effective defense against simple Trojans, but a delayed-trigger virus or Trojan may get past it. -David- *----------------------------------------------------------------------* | (314) 362-3635 Mr. David J.
