 General Comments: 
       The Kemerovo virus was submitted in December, 1990 and is from the 
       USSR.  This virus is a non-resident direct action infector of .COM 
       files, including COMMAND.COM. 
       When a program infected with the Kemerovo virus is executed, the 
       virus will search the current drive and directory for a .COM 
       program to infect.  If an uninfected .COM program is found, the 
       virus will infect it, adding its viral code to the end of the 
       original program.  The newly infected program's date and time in 
       the disk directory will also be updated to the current system 
       date and time of infection.  Infected programs will increase in 
       length by 257 bytes. 
       If an uninfected .COM file was not found in the current directory, 
       the message "????????COM Path not found" may be displayed and the 
       program the user is attempting to execute will be terminated. 
       Kemerovo does not do anything besides replicate. 
       Known variant(s) of Kemerovo are: 
       Kemerovo-B: Similar to Kemerovo, this variant is from the United 
                   States and has been altered to avoid detection by some 
                   anti-viral programs.  Its major distinction from the 
                   original virus is that it will infect five .COM 
                   programs in the current directory. 
       Kemerovo-C: Very similar to Kemerovo-B, this variant only differs 
                   by a couple of bytes.
