I agree with the "sudden death" scenario. With Virus scanners it would be helpful to stop after the first found virus.
If the first scanner is significantly more efficient than the others (such as FProt) then the savings would be amplified quite a bit. Since virus scanners are almost always "dumb" and don't learn anything from the messages they process there is no good reason I can think of to run a second or third scanner if the first has detected a virus. _M On Monday, August 2, 2004, 4:40:27 PM, Markus wrote: >> >When running multiple scanners is their a way to prevent the other >> >configured virus scanners from scanning the message if the >> first virus >> >scanner finds a virus? >> >> No, there is not.
