 General Comments: 
       The Path, or VHP-547, virus was received in November, 1991.  Its 
       origin is unknown.  Path is a non-resident, direct action infector 
       of .COM files, including COMMAND.COM. 
       When a program infected with the Path virus is executed, the virus 
       will search the current directory for one uninfected .COM file to 
       infect.  If it finds one, it may or may not become infected by the 
       Path infected programs will have a file length increase of 547 to 
       562 bytes.  The virus will be located at the end of the infected 
       file.  There will be no visible change to the file's date and time 
       in a DOS disk directory listing.  The following text strings can 
       be found within infected programs: 
       Symptoms of an infection of the Path virus are that some infected 
       programs will hang the system when they are executed.  Others may 
       result in random characters from memory being written to the 
       system display.
