 General Comments: 
       The ARCV 330, or 330, virus was submitted in January, 1993.  It is 
       originally from England.  ARCV 330 is a non-resident, direct action 
       infector of .COM programs, including COMMAND.COM. 
       When a program infected with the ARCV 330 virus is executed, the 
       ARCV 300 virus will infect one .COM program located in the current 
       directory.  If COMMAND.COM is located in this directory, it may 
       become infected.  Programs infected with the ARCV 330 virus will have 
       a file length increase of 330 bytes with the virus being located at 
       the end of the file.  The program's date and time in the DOS disk 
       directory listing will have been updated to the current system date 
       and time when infection occurred.  The following text string is 
       located near the end of all programs infected with the ARCV 330 
       The ARCV 330 virus activates in the month of July of any year. 
       During July, the virus will display the following message and hang 
       the system when an infected program is executed: 
               "[330] by ICE-9" 
       This message is encrypted within the viral code, as is the following 
       text string:
