Malware removal

  • Before removing malware, backup all of your critical system files
  • Create a restore point
    • Open the System Restore panel by going to your system search bar and typing in “restore point”, then clicking on Create a restore point. This will open the System Properties window.
    • Go to the System Protection tab.
    • Click on Create and then enter a description that you will remember.
    • All restore points can be found in System Properties → System Protection → Restore → System Restore → Choose a different restore point. Check that it is in the list.
  • Run a deep system scan using an antivirus tool
  • Remove malware from your computer.
    • If the file is moved to quarantine, but not yet deleted automatically, open the quarantine folder and manually delete the quarantined malware files.
    • Some aggressive malwares may actively stop antivirus tools from running. If this happens, restart in Safe Mode to regain access to your computer and malware removal tools.
      • Windows 7: Restart your computer and when Windows begins to load, press the F8 key in one-second intervals. Windows will load an Advanced Setup screen. Press F4 to enter Safe Mode without internet, or F5 to enter Safe Mode With Networking.
      • Windows 10: Tap the Windows logo button and the “i” button on the keyboard at the same time to open Windows Settings, click on Update & Security → Recovery→ Advanced startup. When restarting, Windows will show a screen that lets you choose your troubleshooting method. Select Troubleshoot → Advanced options → Startup settings → Restart. The computer will restart again, showing more restart options. Select 4 or push F4 to open windows in Safe Mode, or F5 to open Windows in Safe Mode with Networking
    • You may need to install an antivirus scanning and removal tool onto an external drive or a flash drive and run the removal process from there. Not every antivirus tool is accessible or functional in Safe Mode, and the most sophisticated malware may still prevent antivirus tools installed on your computer from operating, even in Safe Mode.
    • Some malware may be so deeply embedded in your file system that they still cause problems even in Safe Mode. In situations like that, you may need to completely remove and then reinstall Windows.
