Trend Micro Chip Away (1993) 1 Utility DOS

Released in the early 90s by the Japanese company Trend Micro Devices, Inc (later just Trend Micro), Chip Away Viruses is a DOS based virus scanner that is intended to run from a hardware product built in to a PC motherboard before the system boots. It includes a custom embeddable DOS (called X-DOS), but it can be run from regular DOS. Trend Micro also produced the products PC Rx (A regular software virus scanner), and PC-cillin (a hardware/software combo that keeps critical boot information in a special device). Users sometimes misinterpreted the name "ChipAway Virus" as being a virus itself.
