 General Comments: 
       The Barcelona virus was received from Barcelona, Spain, in 
       December, 1991.  Barcelona is a memory resident infector of .COM 
       programs based on the Jerusalem virus. 
       When the first Barcelona infected program is executed, the 
       Barcelona virus will install itself memory resident as a low 
       system memory TSR of 2,096 bytes.  It will have hooked interrupt 
       Once Barcelona is memory resident, it will infect .COM programs 
       when they are executed.  Infected programs will have a file length 
       increase of 1,792 bytes with the virus being located at the 
       beginning of the file.  The file's date and time in the DOS disk 
       directory will have been updated to the current system date and 
       time when infection occurred. 
       The following text strings can be found within the viral code 
       in Barcelona infected files: 
               "CATALUNYA LLIURE" 
               "FORA LES FORCES D`OCUPACIO" 
       It is unknown if Barcelona carries any damage potential.
