I doubt that will be possible, whilst viruses are much less seen and most detections nowadays are malware.
Currently in the avast Virus database (another throw back to the days of viruses being the main infection method) there are 6,331,991 signature definitions.
You may do better doing a search, such as this one https://uk.search.yahoo.com/search?p=computer+virus+types.
