FRISK Software International (established in 1993) was an Icelandic software company that developed F-Prot antivirus and F-Prot AVES antivirus and anti-spam service. The company was founded in 1993. It was acquired by Cyren in 2012.



The company was founded in 1993.[1] Its name is derived from the initial letters of the personal name and patronymic of Friðrik Skúlason, its founder.[2] Dr. Vesselin Vladimirov Bontchev, a computer expert from Bulgaria, best known for his research on the Dark Avenger virus, worked for the company as an anti-virus researcher.[3]

F-Prot Antivirus was first released in 1989, making it one of the longest lived anti-virus brands on the market.[4] 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 and Linux. There are corporate versions for Microsoft Exchange, Solaris, and certain IBM eServers.[5][6] The Linux version is 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.[7]

The company has also produced a genealogy program called Espólín[8][9] and Púki, a spellchecker with additional features.[10]

In Summer of 2012, FRISK was acquired by Cyren, an Israeli-American provider of security products.[1][11]

He originally developed F-Prot Antivirus while doing computer support work. He was, for many years, the technical editor of the Virus Bulletin.[15][16] Skúlason served as the head of FRISK Software International until its eventual acquisition by Cyren in 2012, after which he joined Cyren as the vice-president of Antivirus technologies.
