How to Detect a Remote Access to My Computer
Few things are scarier than an active intrusion on your computer (Detect a Remote Access). If you believe that your computer is currently under the control of a hacker, the first thing you should do is disconnect completely from the internet. Once you’re safely disconnected, you can search for the entry point that the hacker used to access your system and remove it. After your system has been safely locked down, you can take steps to prevent more intrusions in the future.
Check for the obvious signs of remote access. If your mouse is moving without your control, programs are being opened in front of your eyes, or files are actively being deleted, you may have an intruder. If you have an active intrusion, your first step should be to power down your computer immediately and remove any Ethernet cables.
Detect a Remote Access
- Slow internet or unfamiliar programs are not necessarily the result of someone gaining remote access to your computer.
- Many programs that update automatically will appear or generate pop-ups during the update process.
Look for unusually high CPU usage. You’ll see this in the Task Manager or the Activity Monitor. While high CPU usage is common, and is not indicative of an attack, high CPU usage while you’re not using your computer could indicate that processes are running in the background, which you may have not authorized. Be aware that high CPU usage could just be a program updating or a torrent downloading in the background that you forgot about.
Run a scan with your antivirus program. You should have an active antivirus program already installed, even if it’s just Windows Defender. Open your antivirus and run a scan of your entire system. This scan may take an hour or so to complete.
- If you don’t have an antivirus, download an installer on another computer and transfer it to your computer via USB. Install the antivirus and then run a scan with it.
