SPAMfighter

SPAMfighter is a Danish company from Copenhagen, trading since the early 2000s, and its original product is the one it is named for: a spam filter for Outlook and Windows Live Mail that worked by community reporting — when enough users flagged a message, it was blocked for everyone. That was a genuinely novel approach at the time and gave the product a large installed base. Its range has since spread across utilities and security under the same naming pattern: VIRUSfighter and VIRUSfighter Server for malware, SPYWAREfighter for spyware, and SLOW-PCfighter, FULL-DISKfighter and DRIVERfighter for maintenance, with SPAMfighter Mail Gateway and Exchange Module for organisations. It is a small vendor and its security products are entered into the independent laboratory cycles rarely; its strength has always been the mail filtering rather than the antivirus.
