Antivirus applications are considered as one of the “must have” programs for any computer. They help in securing your PC (and the data on it) against all kinds of viruses, spyware, and other malicious software. Now, if you have a capable antivirus program installed on your computer, then there’s nothing to worry about. But what if you are work on another PC (e.g. a computer in a public library), that doesn’t have antivirus software installed? Well, that’s where the portable antivirus software comes into the picture.

Like most portable apps, these antivirus programs don’t need to be installed in your PC. You can carry them anywhere in, say, USB drives, and make sure that your systems are safe. Today, we will be taking a look at 6 best portable antivirus software that you can rely on.

Best Portable Antivirus Software in 2019

Before we get into the list, let’s discuss a couple of key points that you should keep in mind before depending on the portable antivirus software.

  • A majority of programs mentioned in our list comes with updated malware definitions database. But for others, you’ll have to update the database manually.
  • Portable antivirus software is not a replacement for your licensed anti-malware product. For all-around, real-time protection, you’ll still have to rely on full-fledged antivirus products.
  • Since portable antivirus software doesn’t have “real-time” scanning, you’ll have to scan files and folders manually every time.

Now, that we’ve learned about the portable antivirus software, let’s take a look at the best portable antivirus software you can use in 2019.
