I certainly understand your concern.

In order to understand the issue more clearly, I would request you to kindly provide me with the following information.

I would like to provide you with the information that RSA-2048 and AES-128 ciphers is a Ransomware virus that has been spread widely for illegal purpose. This virus will allow the cyber criminals to gain access by taking control of the system remotely.

This message can pretend to be a form of law enforcement agency that tells you to pay a fine in order to unlock your crucial files and data. This threat will also stops you from closing your browser by pressing any shortcut keys or using the address bar.

Thank you to all that assisted.  I am a 78 year old great-grandmother who isn't up to date on all computer technology and welcomed all assistance.  My problem has been fixed.  One of my grandsons suggested using the following:

Malwarebytes anti-malware

It worked for me.  If anyone else encounters the malicious virus my computer was infected with, please try it, it may help you as well.  Again, thank you everyone for your time.
