EGABTR (EGA for enhanced graphics adapter),[1] sometimes pronounced "Eggbeater", was a Trojan horse program[2] that achieved some level of notoriety in the late 1980s and early 1990s.[3][4][5][6][7] Allegedly a graphics utility that would improve the quality of an EGA display, it actually was malware that deleted the file allocation tables on the hard drive.[8][9][3] This deletion was accompanied by a text message reading "Arf! Arf! Got you!".[10][6][11] Coverage about this virus has translated in languages such as German, Chinese and Indonesian.[12] Various sources disagree as to the exact wording.
In the 1980s, Richard Streeter, a CBS executive,[13] once downloaded the Trojan virus, learned about EGABTR after visiting electronic Bulletin boards, hoping to find something to improve his operating system and unknowingly downloaded the virus.[14]
