 General Comments: 
       The Tadpoles virus was received in February, 1995.  It is from 
       Cebu City in the Philippines.  Tadpoles is a memory resident 
       infector of .COM and .EXE files, including COMMAND.COM. 
       When the first Tadpoles infected program is executed, this virus 
       will install itself memory resident as a low system memory TSR 
       of 3,232 bytes.  Interrupt 21 and 2F will be hooked by the virus in 
       Once the Tadpoles virus is memory resident, it will infect .COM and 
       .EXE files when they are executed.  Infected .COM files will have 
       a file length increase of 2,792 bytes. .EXE files increase in size 
       by 2,792 to 2,804 bytes.  In both cases, the virus will be located 
       at the end of the file.  The program's date and time in the DOS 
       disk directory listing will not be altered.  The following text 
       string is visible within the viral code in all Tadpoles infected 
               "CCCv (w) CCC CompE... Hail U.C.!" 
       It is unknown what the Tadpoles virus does besides replicate.
