ThunderByte Antivirus

ThunderBYTE Anti-Virus (TBAV) was an early antivirus software program. It was created by Dutch programmer Frans Veldman in 1988 and published by his company, ESaSS B.V. TBAV was mainly made for DOS, but there were also versions for Microsoft Windows. It was known for fast scanning, a heuristics-based scanner, and Anti-Vir.Dat files that tracked known-good file information using checksums.

Originally, ThunderBYTE used a dedicated ISA card to protect the computer before the operating system started. Later, a software-only version was released, which replaced the hardware version. TBAV was distributed as shareware.

In 1998, TBAV was sold to Norman ASA, and the product was discontinued.
