|This error is related to some badly scripted malware.|
Before we attempt a removal I want you to disable the startup entry, reboot to see if you can run any programs and see if you still have the internet.
1) Click "Start" > "Run" then type in msconfig, hit enter.
2) Click the "Startup" tab near the top right of the window.
3) Search through the startup entries for firewall.exe and uncheck it. Click "Apply" then "ok" and reboot the pc.
4) Once the pc has booted up you should get a "user configuration utility" window popup, this is fine click "ok"
Let me know if the error message still comes up, if you have internet and if you are able to run your antivirus and/or antispyware programs.
Also what firewall, antivirus and antispyware programs are installed?
If you are unable to do the above with normal startup try doing it in "safe mode" by tapping the F8 key during startup.
