Most people who work in the industry wouldn't touch Nortons with a 123 parsec barge pole! Kaspersky does have an online virus scanner, which is usually available from:
http://www.kaspersky.com/virusscanner
however it is unavailable at this point of time as they are rolling out a new and improved version.
You could try other online anti virus scanners (trend micro has one, not sure on avast or nod though). I'd strongly suggest this.
