Today’s malware is some of the most significant threats to a home-based or a business computer. If your system gets infected, it will be less likely that you’ll be able to install and run anything on your system.

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