 General Comments: 
       The USSR virus was discovered in October, 1990 in the USSR.  It is 
       an encrypted, non-resident generic infector of .EXE files. 
       Each time a program infected with the USSR virus is executed, it 
       will search the current directory for the first uninfected .EXE 
       file.  If it finds one, it will attempt to infect it.  Sometimes 
       when the virus attempts to infect a file, it will hang the system 
       leaving the drive light on, however most of the time the virus is 
       successful.  Infected files will increase in length by 576 to 586 
       bytes, with the virus located at the end of the file. 
       Systems infected with this virus may go to boot their system from 
       its hard disk only to find that the hard disk's boot sector has 
       been removed, and the master boot sector (partition table) has been 
       damaged, thus rendering the hard disk inaccessible.  This damage can 
       be repaired  using Norton Disk Doctor, or MDisk with the /P option. 
       Infected systems will also experience longer than normal load times 
       when infected programs are executed.  The longer than normal load 
       time is due to the virus searching for a file to infect, and then 
       infecting the candidate file if one was found.
