There is hardly anything that scares you like a personal computer being hacked. If you think your computer is being controlled by a hacker, the first thing you should do is disconnect from the network. Once you are disconnected from the network, you can find and remove the gateway that the hacker used to access your system. Once the system is secure, there are several steps you can take to keep your computer from being compromised.
Steps
Check for signs of intrusion
- Some sure signs that your computer is compromised are the mouse moving when you are not using it, the application opening itself right in front of you, or the file being accidentally deleted. However, you don’t need to worry too much about pop-up ads – many apps with auto-update feature can generate pop-ups during the update process.
- Slow internet speed or strange programs are not necessarily signs of a compromised computer.
- Windows: To view recently opened files, you will press Windows key + E to open File Explorer. Check the “Recent files” section at the bottom of the main control panel for signs of anomalies. You can also view recently opened apps at the top of the Start menu.
- Mac: Click the Apple menu in the upper-left corner of the screen and choose Recent Items . You can click Applications to see recently used applications, Documents to view files, and Servers to see a list of “out-of-the-box” connections. [1] X Research Source
- Windows – Press Ctrl + Shift + Esc .
- Mac – Open the Applications folder in Finder, double-click the Utilities folder, and double-click Activity Monitor . [2] X Research Source
- VNC, RealVNC, TightVNC, UltraVNC, LogMeIn, GoToMyPC and TeamViewer.
- Look for programs that seem suspicious or you’ve never heard of. You can look up information online if you don’t know what program it is.
- Malware is often the easiest way for hackers to get into your personal computer.
- If you don’t have anti-virus software, you can download the program using another computer and save it to a USB to transfer to your computer. Install an anti-virus program and scan your computer.
- Malwarebytes Anti-Malware is a free third-party anti-malware program that works on both Windows and Mac computers. You can download this program for free at https://www.malwarebytes.com.
- When backing up data on an infected computer, be sure to scan each file before backing up. Re-importing the old file can always infect the computer again.
- See instructions on how to format a Windows or Mac computer and reinstall the operating system.
Prevent future intrusion
- See instructions to enable Windows Defender on Windows computers.
- You can also refer to the instructions for installing another antivirus program if you do not want to use Defender. The Windows Defender program will automatically disable it if you install another antivirus program.
- See how to set up port forwarding on your router and make sure none are open unless necessary for the server you’re using.
- See how to configure VPN to establish a connection to a VPN service.
Advice
- Note that your computer may start up on its own to install the update. Many newer computers are set to automatically update the system, usually in the evening when you are not using the computer. If the computer restarts on its own when you’re not using it, it’s because the computer is in Sleep mode to be “wakeed up” to install updates.
- While your computer can be accessed remotely, the chances are usually very low. There are several steps you can take to prevent intrusions.
