The Virus Bulletin prevalence table is compiled monthly from virus reports received by Virus Bulletin; both directly, and from other companies who pass on their statistics.

Reports are included only if they are confirmed, and hence, in conjunction with the WildList, the prevalence table provides a useful indication of the relative prevalence of various virus found in the wild at the time.


Do you have virus statistics to report? VB is always looking to increase the scope of the table, so please get in touch - email for more information.
