Technical Details

Adware:W32/Virtumonde displays pop-up advertisements. These advertisements are usually disguised to hide their origin from Virtumonde.


Virtumonde only affects Windows XP and 2000 installations. To infect a system, the adware installs itself as a Winlogon notification package and locks its own module. The module has a random 5 character name and is installed to the windows\system32 folder. Virtumonde runs hidden from the user.


To enable its advertising-display function, the adware connects to a server and queries for advertisements to display. The adware actively prevents removal by using several different techniques.


Virtumonde is closely associated to Trojan:W32/Vundo and Trojan:W32/Monder. For more details, please see the following descriptions:
