W32/Sdbot disinfection instructions

Resolve is the name for a set of small, downloadable Sophos utilities designed to remove and undo the changes made by certain viruses, Trojans and worms. They terminate any virus processes and reset any registry keys that the virus changed. Existing infections can be cleaned up quickly and easily, both on individual workstations and over networks with large numbers of computers.

Windows disinfector

SDBOTGUI is a disinfector for standalone Windows computers

If you are disinfecting several computers, download it, save it to floppy disk and run it from there.

After removing the worm you should install the Microsoft patch MS03-039 or, on single computers, update with all relevant security patches from Windows update.

This tool reverses the disabling of the registry editor by W32/Sdbot (by default the registry editor is enabled). Read the release notes in SDBOTSFX.EXE for details.

Note: use SDBOTGUI in Safe Mode when removing W32/Sdbot-XC
