FRISK Software International was an Icelandic software company that developed F-Prot antivirus and F-Prot AVES antivirus and anti-spam service.[1] Its name is derived from the initial letters of the personal name and patronymic of Friðrik Skúlason, its founder. The company was founded in 1993.[1] It was acquired by Commtouch (now known as CYREN) in 2012.

Frisk Software competes in the antivirus industry against Avast, Avira, ESET, F-Secure, Kaspersky, McAfee, Panda Security, Sophos and Symantec among others.


F-Prot Antivirus is one of the oldest antivirus products, with its first release in 1989. It was the world's first with a heuristic engine.[2] It is sold in both home and corporate packages, of which there are editions for Windows, Linux, and BSD. There are corporate versions for Microsoft Exchange, Solaris, and certain IBM eServers.[3][4] The Linux and BSD versions are available to home users free of charge, with virus definition updates. Free 30-day trial versions for other platforms can be downloaded.

F-Prot AVES is specifically targeted towards corporate users.[5]

The company has also produced a genealogy program called Espólín[6][7] and Púki, a spellchecker with additional features.[8]

In Summer of 2012, FRISK was acquired by Cyren, an Israeli-American provider of security products. Friðrik Skúlason, joined Cyren as the vice-president of Antivirus technologies.[9]

TypeAntivirus software

F-Prot Antivirus is an antivirus product developed by FRISK Software International. It is available in related versions for several platforms. It is available for Microsoft Windows, Microsoft Exchange Server, Linux, BSD, Solaris, AIX, IBM eServers and *nix.

The scanning engine used by F-prot provides signature based detection capability, heuristics, and low use of the computer's resources. In 1991, F-PROT Antivirus (for DOS) became the world's first heuristic behavior scanner. F-PROT for DOS has since been discontinued.

FRISK Software International allows others to develop applications based on their scanning engine, through the use of a SDK specifically released. Many software vendors use the F-Prot Antivirus engine, including SUSE. Their SDK is known today as the Commtouch Antivirus SDK.
