Spamihilator is a free program to fight against unsolicited e-mails of an advertising nature (so-called spam). The application works in the "background", capturing suspicious e-mails and then placing them in a special folder. Spamihilator is widely recognized as one of the most effective thanks to extensive verification of sent messages.

In addition to the popular and effective so-called self-learning filter, Bayes also offers a DCC filter, which blocks messages classified as spam by a specific group of other users. An additional advantage of the program is the possibility of increasing its functionality by means of additional plugins. It works with all the most popular mail programs.
