  • Anti-theft support
  • Webcam protection

An antivirus program needs to be fast, efficient, and cost-effective, and this one has them all.

Today’s malware is one of the most significant threats to a home-based or a business computer.

To overcome such a situation, it’s recommended that you have an offline/portable virus scanner to scan your Windows 10 system.

A PC that became severely infected may also not have access to the Internet anymore, and that’s why a portable virus scanner plays such a crucial role in your computer.

We’ve listed five of the best offline antivirus programs that are portable tools, and this means that you’ll be able to easily run them from a USB stick for instance.

Check out all their features and see which one seems to fit your security needs best.
