{{Short description|Early antivirus software}} {{Inline citations|date=December 2023}} {{Use mdy dates|date=January 2025}} '''ThunderBYTE Anti-Virus''' (TBAV) was an early [[antivirus software]] product. It was created by [[Netherlands|Dutchman]] Frans Veldman in 1988, and published by his company, ESaSS B.V. It was mainly designed for [[DOS]], but there were also versions supporting [[Microsoft Windows]]. TBAV was known for its fast scan speed, heuristics-based scanner, and <code>Anti-Vir.Dat</code> files tracking known-good file information ([[checksum]]s).{{Citation needed|date=March 2025}}

Originally ThunderBYTE used a dedicated [[Industry Standard Architecture|ISA]] card to provide protection before the [[operating system]] was even loaded. Later, a software-only product was released, which soon displaced the hardware offering. It was distributed as [[shareware]].

In 1998, TBAV was sold to [[Norman ASA]],<ref>{{Cite web |last=Writer |first=CBR Staff |date=1997-04-07 |title=NORMAN DATA DEFENSE BUYS EUROPEAN WINTEL ANTI-VIRUS PARTNER |url=https://techmonitor.ai/technology/norman_data_defense_buys_european_wintel_anti_virus_partner |access-date=2023-12-08 |website=Tech Monitor |language=en-US}}</ref> which discontinued ThunderBYTE as a product.
