 General Comments: 
       The Tease or Tease.840 virus was received in January, 1996, and 
       appears to be from Sweden.  Tease is a non-resident, direct 
       action infector of .COM files, including COMMAND.COM.  It only 
       infects files on the system hard disk, not diskette drives. 
       When a program infected with the Tease virus is executed on the 
       system hard disk, this virus will infect all of the previously 
       uninfected .COM files located in the current directory, as well 
       as the drive's root directory and the C:\DOS directory. 
       Programs infected with this virus will have a file length 
       increase of 840 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 not be altered.  The following text strings are 
       encrypted within the viral code: 
       "This virus is a direct-action infector of .com files that will 
        search for files" 
       "to infect in the current,  DOS and in any directories below 
        this.  If it find an" 
       "un-infected com file it will be infected, though still work 
        as before. The virus" 
       "is freeware, and you are allowed and even encouraged to copy 
        it to your friends"
