Action

Please follow the instructions for removing Trojans.

Windows NT/2000/XP/2003

In Windows NT/2000/XP/2003 you will also need to edit the following registry entry. The removal of this entry is optional in Windows 95/98/Me. Please read the warning about editing the registry.

At the taskbar, click Start|Run. Type 'Regedit' and press Return. The registry editor opens.

Before you edit the registry, you should make a backup. On the 'Registry' menu, click 'Export Registry File'. In the 'Export range' panel, click 'All', then save your registry as Backup.

Locate the HKEY_LOCAL_MACHINE entry:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
DSB = C:\Program Files\DSB\DSB.exe

and delete it if it exists.

Close the registry editor.

More Information

Troj/WindFind-C is a downloader Trojan which may download and run executables from a remote location.

The Trojan creates the folder C:\Program Files\DBS\ and copies itself to the file DSB.exe in this folder, then creates the following registry entry so that the Trojan is run automatically each time Windows is started:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
DSB = C:\Program Files\DSB\DSB.exe

Troj/WindFind-C runs continuously in the background, waiting until the user performs an internet search using one of the common search engines, such as Yahoo, Lycos, MSN Search, Google, Altavista, or Excite.

The Trojan then attempts to download an executable from a remote location to the Windows TEMP folder and execute it.
