Dear ArunYogi
Thank you for posting in the Microsoft Community!
I understand that you have received a hacked email from yourself.
I recommend that you immediately disconnect your computer from the Internet and try to log in to your Microsoft account on another device that is in a secure environment, as it is likely that your computer has been infected by a hacker programme. If you are able to log in successfully on another device, you should immediately turn on your Microsoft account's two-step verification system, which greatly improves the security of your Microsoft account. If your password has been tampered with, please click [Forgot Password] on the login screen to see if your account security information has also been changed (Note: If your security information is accessible, please be sure to change your password in a secure network environment). If both your password and account security information have been changed, you can only try to find Microsoft's online technical support and ask them for a more professional solution. Click on this link Contact - Microsoft Support And follow these steps to find them.
- First enter your question into the search, then click "Sign in to contact support" at the bottom of the page.
- Currently logged in to another valid Micorsoft account.
- Under "Products and Services", select "Other Products".
- Under Categories, select Manage Account Security, and then click Confirm.
- Click Chat with Support Agent in Web Browser.
After your computer has been disconnected from the Internet, please use antivirus software to carry out virus checking. If your computer still shows signs of virus infection after the antivirus process, please contact a professional third-party Internet security company for assistance.
Finally, it is recommended that you reduce your visits to dangerous websites in order to reduce the risk of your computer being infected by malicious levels.
I hope that my reply has been helpful to you! If you have any other questions, reply to me at the bottom of this post at any time!
I wish you all the best
