What nVIR 10 does is act as a switch to the nVIR virus to tell it not to propagate. It doesn't really do anything else, and it won't help against any other virus. nVIR only looks at the System folder to see if nVIR 10 is there; it doesn't look at other files. I'll check into some things I have, and post back if I find anything that will work with the old System. Could you please drop me a note and let me know exactly what version you're running? Thanks. --- Joe M. P.S. If I come up with anything, I'll be sure to post it on our LISTSERV and will send it to sumex, too.
