 General Comments: 
       The 1008 virus was discovered in June, 1990 by Petteri Jarvinen of 
       Helsinki, Finland.  It is a memory resident .COM infector, and will 
       infect COMMAND.COM.  This virus is also sometimes referred to as 
       the Suomi virus. 
       The first time a program infected with the 1008 virus is executed, 
       the virus will install itself memory resident.  COMMAND.COM is also 
       infected at this time, resulting in its length increasing by 1,008 
       Bytes.  The increase in file size of COMMAND.COM cannot be seen by 
       doing a directory listing if the virus is present in memory. 
       Booting a system with an infected copy of COMMAND.COM may result 
       in an internal stack error, and the system being halted.  This 
       effect was noted on the author's test machine which is a 640K 
       XT-clone running Microsoft MS-DOS Version 3.30. 
       After the virus is memory resident, it will infect any .COM file 
       which is executed, adding 1,008 bytes to the file length.  The file 
       length increase cannot be seen by doing a directory listing if the 
       virus is present in memory.
