The first thing you should know about this virus is that it blocks antivirus software, disables Task Manager and Registry Editor (regedit). The reason of all this is actually very simple – to protect itself and make the removal process very complicated. What is more, this virus comes with rootkit infection. That means you shouldn’t even try to remove it manually. Why? Because it’s very hard or even impossible to remove rootkits manully. So, what next? There are two methods that might work for you. The first is when you remove the rootkit infection and stop the Live Enterprise Suite processes and the second one is using Safe Mode with Networking. If the first fails then try the second one.
Live Enterprise Suite removal instructions:
Method #1
1. Download TDSSKiller tool from Kaspersky and save it to Desktop.
2. Extract tdsskiller.zip file and double-click on TDSSKiller icon to launch it.
3. The scan will start automatically and may take a while. When the scan is finished close all programs and press “Y” key to reboot your PC.
4. Download one of the following anti-malware applications (all free):
5. Install the selected application, update it and run a full system scan. You may also install another application from the list to make sure that the first one removed all infected files.
Method #2
Reboot your computer is "Safe Mode with Networking". As the computer is booting tap the "F8 key" continuously which should bring up the "Windows Advanced Options Menu" as shown below. Use your arrow keys to move to "Safe Mode with Networking" and press Enter key.
NOTE: Login as the same user you were previously logged in with in the normal Windows mode.
Download SUPERAntispyware, MalwareBytes Anti-malware or Spybot - Search & Destroy and run a full system scan. Don't forget to update the installed program before scanning. Then reboot your computer in "Normal Mode" and run a system scan again.
