Can you tell if someone is accessing your computer?
Checking for unauthorized access involves reviewing system logs, active network connections, unknown user accounts, and unfamiliar running programs. Common indicators include the mouse moving on its own, unexpected pop-ups, or apps opening without your command.
Check Windows Logs and User Accounts
Press the Windows Key + R, type eventvwr, and open Windows Logs > Security to inspect logon events and exact login times. Press Windows Key + R, type netplwiz, and review all registered user accounts to ensure no unknown profiles exist. Open Remote Desktop settings to verify that remote access is turned off and no unauthorized users are listed.
Inspect Mac Activity and Logs
Open Activity Monitor, select the Network tab, and look for high data usage or unknown active connections. Open the Terminal app and type last to review a detailed chronological history of recent user logins. Go to system settings or use the Apple menu to check your Recent Items for unfamiliar document or app activity.
Review Running Apps and Network Traffic
Open the Task Manager on Windows or Activity Monitor on Mac to check for unfamiliar background tasks or remote utilities like TeamViewer or AnyDesk. Scan your system fully using a trusted anti-malware or antivirus program to find hidden backdoor tools. Disconnect from the internet immediately if you spot active tampering or active remote control.
Comparison of System Diagnostic Tools
Different operating systems provide built-in tools to monitor security and user activity.Windows Event Viewer
• Inspects system logs and login events.
• Accessed via the Run command using eventvwr.
Mac Activity Monitor
• Monitors network connections and data usage.
• Located within system applications for resource tracking.
Both tools help identify suspicious activity, though Windows relies heavily on log auditing while Mac focuses on real-time process monitoring.Detecting Unwanted Remote Access
