%%Notes: Infects MBR and 1.2MBoot sector, may remove itself on the next 
bootstrap and does nothing else 

Another report says that it replicates just fine, when first run, 
infects MBR, after a boot, it removed itself from the MBR but stayed in 
memory if there are UMBs available.  Then it companion-infects EXE files 
under 64K that are executed. It refuses to run any exe file bigger than 
64K that ends in "AN' - "AZ" (including scan, tbav, resscan) and messes 
up the CMOS if you do.
