It sounds like you are experiencing a serious issue with unauthorized access to your computer. Here are some potential explanations and steps you can take to address the situation:
- Remote Access Software: There are various remote access tools that can allow someone to control your computer from a distance. If you suspect that someone is using such software, check your installed applications for any remote desktop software that you did not install yourself. Common examples include TeamViewer, AnyDesk, and others.
- Tech Support Scams: Be aware that tech support scams often involve scammers tricking users into giving them remote access to their devices. If you did not initiate the connection with a trusted source, it is crucial to be cautious. Microsoft will not contact you unsolicited to request access to your device.
- Malware: Malware can be used to gain unauthorized access to your computer. Ensure that you have a reputable antivirus program installed and that it is up to date. Run a full system scan to check for any malicious software.
- USB Devices: If you suspect that your USB keyboard might be compromised, consider using a different keyboard or disconnecting it to see if the issue persists. Malicious individuals can sometimes exploit vulnerabilities in USB devices.
- Account Security: Change your passwords and enable two-factor authentication on your accounts where possible. This can help prevent unauthorized access.
- Network Security: Ensure that your home network is secure. Change the default password on your router, and consider using a firewall to protect your devices from external threats.
- Physical Security: Since you mentioned concerns about someone breaking into your house, it may be wise to enhance your physical security measures as well.
If you continue to experience issues, it may be beneficial to consult with a professional technician who can help diagnose and resolve the problem more thoroughly.
