There are 2 variants:
When the virus is loaded into memory, it infects first 4 uninfected executable in both DOS and EXE formats, i.e. 8 files, followed by hooking INT 21h and 7Eh to infect any executable that is run, plus 3 extra files, i.e. the virus infects 4 files on every run.
If the file to be run has been already infected, the virus searches for other 4 uninfected files in same format to infect.
The virus consumes about 8K in memory.
Both variants check and ignore files having any of the filenames:
COMMAND SCAN CLEAN NAV CPAV BOOTSAFE
