Signs that your computer has been hacked

If you think your computer has been hacked, and have Norton installed on your computer, the best option to rule out a threat infection is to perform a full system scan. However, there may be instances where the scan did not detect any threat, or you cannot perform a scan. In these scenarios, we recommend that you run a scan using Norton Power Eraser. Norton Power Eraser is a free, downloadable tool that uses aggressive methods to detect threats.

Many Norton offerings come with an additional benefit called the Norton Virus Protection Promise, which includes access to Norton experts who can work with you to diagnose and remove viruses should you run into any problems during your subscription. For more information, read What is Norton Virus Protection Promise?

How do I know that my computer is hacked?

If your computer is hacked, you might notice some of the following symptoms:

  • Frequent pop-up windows, especially the ones that encourage you to visit unusual sites, or download antivirus or other software

  • Changes to your home page

  • Mass emails being sent from your email account

  • Frequent crashes or unusually slow computer performance

  • Unknown programs that startup when you start your computer

  • Programs automatically connecting to the Internet

  • Unusual activities like password changes

Download and run Norton Power Eraser

  1. Download Norton Power Eraser.

  2. Click Save.

  3. Select the location as Desktop, and then click Save.

  4. To run Norton Power Eraser, double click the NPE.exe file.

    If the User Account Control window prompts, click Yes or Continue.

  5. Read the license agreement, and click Accept.

  6. In the Norton Power Eraser window, click the Scan for Risks icon.

  7. By default, Norton Power Eraser performs a Rootkit scan and requires a system restart. When you see a prompt to restart the computer, click Restart. If you do not want to include the Rootkit scan, go to Settings, and uncheck the option Include Rootkit scan (Requires a system restart).

  8. After the computer is restarted, the scan starts automatically. Follow the on-screen instructions.
