Details
Marzia.2048.WW
This is a dangerous memory resident multipartite stealth virus. On execution of infected file it infects MBR of hard drive. Then it hooks INT 13h, 21h. On loading from infected sector it hooks INT 13h, waits for DOS loading and hooks INT 21h. On accessing to infected MBR (virus checks it by using INT 13h hooking) it substitutes it by not infected one. By hooking INT 21h the virus intercepts the files for infection.
On installation it traces INT 13h and hooks INT 1Ch. It writes itself at the end of COM and EXE files are executed or closed. On opening of the infected file this virus cures it.
Depending on current date the virus erases the hard drive sectors or call INT 24h. On calling INT 21h, AX=3031h the virus decrypts and displays the message:
