You might need physical intervention..

Virus Removal
Once the computers are removed from the network and updated with current definitions, the virus should be removed and the changes affected by the threat reversed.
Here are the steps to clean a virus once virus definitions are up to date.
A. Stop the viral process, or boot the computer to a state where the process is not loading
i. End the task - some threats may prevent this.
ii. Start Windows in Safe Mode or Safe Mode Command Prompt only
iii. Newer versions of Symantec AntiVirus (version 10) and Symantec Endpoint Protection may be able to stop the process as part of a full system scan.
B. Remove the viral files
i. Full system scan – Recommended
ii. Manually remove the files by finding and deleting them
iii. Check if there is a removal tool available for the particular threat variant.
C. Reverse the changes to system settings. It is important to make changes to the registry before rebooting the computer. Many viruses change boot setting so the user may be unable to log in once the virus is removed, if the registry changes are not undone.
i. Undo Registry Changes
ii. Undo changes to the following files – if necessary
1. hosts
2. win.ini
3. sfc.dll – may need to be replaced with new copy
4. Anti-virus and Firewall programs – may need to be reinstalled.
D. Reboot the computer into normal mode, before connecting it back to the network. This is to determine that no additional viruses are detected and the cleaning was successful.
E. If a rootkit or backdoor is detected it maybe necessary to re-image the computer to ensure security of the network.
