MikeBCda, I doubt there’s any “official” number posted anywhere - simply because of the reason you explained. Detection of one virus family may be counted as “one virus” by one antivirus, an as “500 viruses” by another - so, there’s really not any point in comparing the numbers.
You can run avast!, enter the Virus Database dialog and let all the viruses be selected (search for *) - I believe there’s a number of found items shown somewhere in the window. As I said, however, this number has hardly any sense.
