8 of the Best Lightweight Antivirus Software for Windows 10

The Internet has reinvented modern living in the past decade because it made our lives easier. With it, we can communicate, play games, and work efficiently, all with one click. However, the price we pay for a connected life is our security because there’s always a chance that a cybercriminal may invade our private data. Luckily, this can be avoided with an antivirus.

An antivirus prevents digital threats from getting into your system by identifying and deleting them. Most are robust and can protect multiple devices, but these are usually paid versions. The good news is that plenty of lightweight antivirus software is out there, and they can also work on weaker computers. The tricky part lies in looking for them, which many fail to do. For this reason, we’ve gathered some of the best lightweight antivirus software for you. These include:

#1 – Avast Free Antivirus

Avast Free Antivirus is awarded as the world’s best antivirus and is also one of the most lightweight security apps. One of the reasons why we choose it as the best antivirus is because it’s so easy to install and run. It has a minimalistic interface but runs quietly without interfering with regular computer use. This is why it’s not just a lightweight antivirus but a friendlier security software. Weighing only about 400MB, it won’t eat your storage space.

#2 – Avira

Avira’s claim to fame is being able to block infected websites, which is a handy feature for those who like to surf the web. Unlike most security software, it’s very user-friendly, allowing you to customize how you want your device to be protected. It’s also one of the few free security software that can encrypt your hard drive, ensuring you have a good antivirus.

#3 – AVG Free Antivirus

AVG can do many things, such as provide real-time security updates, improve performance, and filter malicious downloads before they even run. Apart from the standard malware scans, AVG can also block unsafe websites, allowing you to surf to your heart’s content. It also runs silently in the background without compromising your computer’s speed, which is a disadvantage of other antiviruses.

#4 – Bitdefender

Bitdefender uses AI to build a defense system that works closely with your system. It also has a unique vulnerability scanner and can block viruses before they enter your system. These are all lightweight features and don’t slow down your computer, making it a good choice if you want security software that doesn’t occupy a lot of space.

#5 – Kaspersky Antivirus

Kaspersky Antivirus is reliable security software that’s well-known for its superior speed, being able to detect and remove even the most sophisticated threats. It has a low impact on the overall system performance, doing its job while you run your digital life. It can also prevent malicious downloads from running on your computer.

#6 – Panda Security

Cloud technology is a relatively new concept for antivirus software, but Panda Security is a leader in the cloud security industry. It uses a cloud-based protection system that can detect malware even if it’s not yet registered in a database. Furthermore, it has a Botnet Protection System, which protects your network from being hijacked by hackers.

#7 – Systweak Antivirus

Systweak Antivirus is security software that prides itself in using the smallest footprint possible, making it the perfect antivirus for people with limited computer resources.
