Hello, I am Navid, and I am an Independent Advisor. I will do my best to help you.
It seems that your Laptop is strongly infected. But to be sure, please tell me the exact name of your antivirus, and what really helps to recognize the problem is that you send me a screenshot from one of these messages.
Then, I will provide you an exact step-by-step solution to get rid of this problem.
Best,
Navid Dariya
