%%Notes: v6-146: This virus was written to hurt users of the TBCLEAN 
antivirus package.  If you have a file infected with the Varicella 
virus, and if you tried to clean this virus infected file with tbclean, 
what would actual happen is that tbclean will report "that this file is 
not infected by a virus" but what _actually_ happen was that the virus 
escaped the controlled environment that tbclean setup to try to 
disinfect the file, and the virus will go resident and hook interrupts 
21h,13h,8h,1ch. and it will allocate memory under the TOM, and fool 
tbclean in reporting that no virus is in the file, and tbclean will exit 
normally! 
whereby, in fact the varicella virus went resident and is now infecting 
the system. and to advice you, the varicella virus is fairly a stealth 
virus that disinfects files on the file, when opened and reinfects them 
when closed,  and it hides its virus length very well! such a virus can 
easily get out of control on a huge level.
