#4 Stops a 2nd virus scan if the 1st scan found a virus

[Gerard Earley]

I have discovered that when an infected mail is found by clamav it is once again being scanned by trophie/sophie/sophos.

Now its my understanding from the code that a positive hit from one virus scanner is enough to have the mail canned, so in that case performing a second scan is a total waste of time if the first scan was positive.

I attach a patch with overcomes this by simply checking the existing FoundVirus variable before doing a second virus scan.

While running in debug, no second trophie scan is being perfomed after a positive clamAV scan, when testing with the eicar test virus.
