Zerobug.1536
It is a memory resident not dangerous virus which inserts itself into COM-files beginning at their creating: the infector hooks INT 21h, f.3Ch, creates the file, writes its body into this file and returns the control back to the program that called this function. And then that program appends the COM-file which is created to virus body. As a result the virus deceives much of the antiviral monitors; and not needed to check INT 24h. This infector has a interesting manifestation: it runs the small face (ASCII 01h) which moves on the screen and erases all zero symbols ('0'). It hooks INT 1Ch, 21h. |
