Getting rid of all the faults

I am receiving emails asking me to send 2000 bitcoin saying I watch adult videos and they have video of me masturbating and they will send it to 5 of my friends. I received the same letter from two different names all foreigners.

Hello Padraic. Could you please elaborate more on your issue so that it will be easier for us to assist you better?

Is all thing right have you cleaned my computer of everything

Thank you for clarifying, Padraic.
From your messages, it seems to be a scam email.  Initially, you can be rest assured that your computer would be protected against emerging threats & hackers, with AVG instlaled on it. Reason being, it has an active firewall. 
In order to ensure the same, we'd suggest you to scan your computer using AVG. Additionally, you can change your email account password. If you're using an email client such as Microsoft Outlook or Mozilla Thunderbird, you can configure AVG Antispam to filter spam emails. 
Thank you for your understanding in advance!
