Barrotes is a computer virus, considered as the first of Spanish origin,[1][2][3][4] which appeared in December 1992,[5] and was programmed in assembly language for DOS-based systems. Initially, although to a lesser extent, it was also called Toledo by the press,[6][1] due to the location in the homonymous city of its first discovery, and registered as Virus:DOS/Barrotes by Microsoft.[7]
Like many viruses of the time, it remains dormant in the affected machine, waiting for a specific date to execute its malicious code, also called payload, with the date chosen by its developer being 5 January, a very important date in Spain, as it is the night of the Biblical Magi, displaying the message «Virus BARROTES por OSoft» and the on-screen graphics of the characteristic bars that give it its name and make it look like the system is in a prison cell.[8][2][9]
