Computer won't let me uninstall Rocket Search?

I have a Lenovo ideapad s400 touch, and today I came across a virus that has infected Google Chrome. I have searched on how to uninstall WSE Rocket from my device, but every time I click 'Uninstall' it says

You do not have sufficient access to uninstall WSE Rocket

Use Revo Uninstaller for removing these kind of junk. It will remove from the bottom of your system files and registry so in future you will not face these type of problems.

Reboot your laptop. On the very first screen that comes up which is before windows starts booting up, press f8 continually until it prompts you to either start windows normally or in safe mode. Select safe mode, not safe mode with networking, just safe mode.

Once windows has booted in safe mode proceed to uninstall that dirty virus.

That should work.
