Comments
The mother of all Trojans is back
and better then ever(trojan wise). Now it infects Windows
NT unlike version 1.20. To make it more dangerous it is
totally open source. Currently this is the most dangerous
trojan around. More about it later maybe.
How To Remove
Quick fix:
None.
Trojan B' Gone
plugin: None yet.
Manual removal:
- Due to the
fact it is open source this will only work for
the default version we recieved not configured
versions
- Remove the UMG32.EXE key located in
the registry at: HKEY_LOCAL_USERS\SOFTWARE\Microsoft\Windows\CurrentVersion\RunServices\.
Which
can be done with regedit or any other registry
editing program.
- Reboot the
computer, or close it.
- Delete the
trojan file UMG32.EXE in
the Windows
System directory.
