It is originally from Brazil, and may date back to late 1990. This virus is a non-resident, direct action infector of .COM programs, but not COMMAND.COM. When a program infected with the Brazilian Bug is executed, the virus will infect all .COM programs other than COMMAND.COM located in the current directory. Once it completes infecting all the .COM programs, it will display the following message: " ****** HELLO FRIEND ****** WE ARE SORRY TO INFORM YOU THAT YOUR SYSTEM IS VERY ILL AND WILL NOT SURVIVE MUCH LONGER YOU UNFORTUNATELY HAVE - THE BRAZILIAN BUG - FOR WHICH THERE IS NO CURE WE HOPE THIS WILL NOT BE AN INCONVENIENCE TO YOU LOVE, THE MAGIK MUSICIANS" The host program will then complete execution. Programs infected with the Brazilian Bug will have a file length increase of 1,343 bytes with the virus being located at the end of the infected file. The program's date and time will have been updated to the current system date and time when infection occurred. All of the above text strings are visible in the viral code in infected programs.
