The Virus Bulletin Virus Prevalence Table, which ran from 1992 until 2013, gave users a regular snapshot of what was really going on in the virus (and later malware) world, recording the number of incidents of each virus reported to VB in the preceding month. In August 2000, Denis Zenkin, a self-confessed virus prevalence table junkie, shared his findings following a study of the virus prevalence tables over the preceding few years, allowing him to determine the top ten viruses of the period, the top viruses by type and the viruses of the year.
