From windows, click Start, then Run and type msconfig. When msconfig opens, click the Startup Tab and look for any program that is set to run at startup that may be unknoown and causing this problem.

Having identified it untick the box to the left of the suspect program (if there is more than one don’t go mad only do one at a time), run cwshredder again and reboot.

Hopefully this will take you a step further.
