How to scan and secure your computer

Comodo Free Antivirus uses advanced isolation technology to keep your system safe. Follow these steps to set up your primary defenses:

  1. Run a Full System Scan
    After installation, open the main dashboard. Click on the Scan button and choose Full Scan. This will check your entire hard drive and registry for existing malware, spyware, and hidden threats.
  2. Enable the Auto Sandbox
    Ensure that the Auto Sandbox Technology is turned on. This feature acts as a virtual operating panel. When you download an unknown or suspicious program, Comodo will automatically run it inside this secure virtual space so it cannot make permanent changes to your real Windows system.
  3. Schedule Automatic Scans
    You do not need to remember to scan manually. Go to the settings and set up personalized protection by scheduling virus scans to run at a specific time, such as late at night when you are not actively using the computer.
  4. Use Game Mode
    If you are playing a full screen video game, enable Game Mode. This temporarily suppresses pop up alerts, virus database updates, and scheduled scans so your gaming performance remains uninterrupted.
Pro Tip: When doing online banking or entering credit card information, launch the Secure Shopping feature. It runs your browser in an isolated environment that prevents other processes or memory scraping malware from stealing your data.
