A clean and simple way of ridding of Ransomware

I discovered that Ransomware infected my PC the other evening whilst I was surfing the web. Once infected it carried out the following functionality:

• Completely locked me out of the system including the keyboard and mouse (apart from the keypad)
• A banner that took up the whole of my monitor appeared with a "policeman" giving a stop signal to me.
• Content included: "This computer has been locked due to known criminal activity including the following: Child Pornography, Gambling, Copyright Theft etc". In addition there was a section where the malware must integrate with your local webcam where it quotes "We are watching you" with the output of the webcam integrated on the banner.
• Also - it resolves your IP address. ISP and location using an internet connection to make it look more realistic.
• Finally - it stated that to unlock the computer - Please dial a number and pay 100 GBP. A keycode will be be provided to unlock the computer.

Now I have read online on how to get rid of the malware and they suggest to run anti-virus and anti-malware software. However that does not get rid of it instantly. I came across the issue recently and performed the following quick, clean and simple procedure:

• Disconnect from the internet - this will stop the banner from starting
• Perform an unexpected reboot of your PC and boot into Windows Safe mode
• Go to Start > Run > and type 'msconfig'
• Locate to the startup tab and scroll down to near the bottom
• Untick any unfamilar startup entries that are in another language or does not fit in to your other startup entries, click Apply, OK.
• Find out the location of the start up program and remove it (if you attempt to so this on normal boot of windows you will get an error).
• Reboot your system

As a precaution it may be worth running your antivirus and antimalware scans just in case you oversee other potentially threatening files.
