And if the machine you are using is running Windows 10, check out this post.

What is a Portable Antivirus Software?

The traditional and standard type of antivirus software can be installed on your computer. And whenever you work from that computer, it will protect your privacy and safety. But portable antivirus applications work differently. They can scan files and get rid of malware easily and quickly, and you won’t even have to install them on your corresponding PC. You can carry around these antivirus programs easily in a pen drive or a USB drive, SD card, etc. and connect it to a different computer to scan that PC.

Whatever PC you connect it with, it will start scanning for viruses and spyware so that you can feel safe online. Portable antivirus software is often installed on portable devices to make sure that the devices are also safe along with the computers they are connected to. But if people are aware of the presence of malware on the internet, then why would you need portable antivirus software in the first place?

Why Should You Use a Portable Antivirus?

Here is the thing, even though many people use computers and laptops, not all of them are aware of the cybercrimes that are happening worldwide. Cybercrimes do include not only hacking but also phishing, ransomware attacks, and malware or other viruses that can damage your files. Now, if any person’s computer you are using for the first time, and you don’t know what’s in there, the best way to keep yourself safe is by using a portable antivirus.

You will just connect your portable device to that computer, and it will automatically start scanning for viruses without going through an installation. Unlike other antivirus programs, you won’t have to install this one, and that’s the best reason why you should use portable antivirus software. Also, if you have an old computer that is infected with viruses and you don’t know how to get it removed, you can use the portable antivirus software technique. You can download the antivirus from a healthy PC and use the program to get rid of the viruses on your old system.

You can carry this antivirus software on even a compact disk (CD) or any other media disks. We will talk about the top 10 portable antivirus software for Windows 10. But before that, we are going to show you how to use these types of antivirus applications. Check out the section below.

How to Scan Your PC with an Antivirus Software?

Let’s go through the steps for using a portable antivirus program on your Windows PC.

Step 1: Open a web browser on your computer that is not infected with a virus or already has an antivirus installed.

Step 2: Search for and download one of the antivirus tools we have mentioned later in this post. If you don’t have a non-infected computer of your own, you can ask a friend for a favour or visit an internet cafe that already has antivirus software installed. Note that you don’t need a Windows 10 PC to download the software. You can download it from any computer, such as a Mac or Linux. But for the antivirus to work, make sure the computer you are using it on is Windows 10.

Step 3: Find a media drive such as a pen drive or SD card to store that antivirus. Copy whatever data it comes with and put that into that portable drive.

Step 4: You can start the infected computer on Safe Mode (safe mode starts the computer without any internet access) and connect the portable device to it with the antivirus in it. As soon as you connect it to your computer, it will show you a prompt to scan the system.

Step 5: Double-click on the antivirus to run in on the computer. Some antivirus will work on the Safe Mode without an internet connection, but some will not. When you are downloading the software, look for this special feature.

Step 6: The antivirus will run and scan for viruses on your PC. When it finishes, you can restart your computer.

Most antivirus won’t ask for your permission before deleting the malicious files from your infected PC. But if it does, you need to remove those files, particularly in order to get your computer back to normal. But what kind of viruses can be there on your PC, and how do they damage your computer?
