Hi Igor, thanks for replying.
No, I dont always use the same settings, but the last one I did was done using the standard scan and I compared to it previous scans on the same setting, and thats when I noticed the difference this time.
Not sure if makes a difference, but when my VRDB was updating, when it had finished I had message up saying error occured while updating, so I did another manual update just before I did the scan this morning.
