Only if you keep your rescue disk set current with the latest definitions (otherwise you're stuck with the defs from the emergency disk that came in the box, which isn't so bad if you've got a very recent version of NAV). Most people wouldn't think of that until it's too late (despite the alerts in the Nav program that rescue disks need to be updated... "surely that doesn't mean me").

So: What are all NAV users going to do today? Check for a LiveUpdate and make a current rescue disk set, if you haven't already. This could really save your ass. (However, if your defs are always current, and you run Autoprotect and practice safe computing you'll never get to the point where you'll need an Antivirus rescue disk)

The rescue disk is only good for a specific PC though because it contains system specific information.

>BTW, NAV does have a DOS level virus utility.
