==History==
F-Secure was first established under the name Data Fellows by Petri Allas and [[Risto Siilasmaa]] on May 16, 1988. Data Fellows trained computer users and built customized databases. Three years later, the company launched its first major software project and developed the first [[heuristic]] scanner for [[antivirus]] products. F-Secure’s first antivirus product for [[Microsoft Windows|Windows PCs]] was launched in 1994. Data Fellows became F-Secure in 1999. F-Secure was the first company that developed an anti-[[rootkit]] technology called BlackLight in 2005.<ref>{{cite web|url=https://www.bleepingcomputer.com/tutorials/use-blacklight-to-remove-rootkits/|title=Using Blacklight to detect and remove Rootkits from your computer: Home|publisher=BleepingComputer}}</ref>
