Windows XP was released for manufacturing on August 24, 2001, and was supported by Microsoft until April 8, 2014.

During those years, the operating system became widely adopted, and to this day still holds over 5% of the desktop market share according to NetMarketShare.

If you happen to be a part of those Internet users that are on Windows XP, finding a good third-party antivirus should be a high priority.

It is very important since the operating system has gone unsupported for over 5 years now. But before that, you should make sure you are as up to date as possible.

So, is there a free antivirus for Windows XP? The answer is yes, and Panda Antivirus is one of the best options out there.

This virus protection tool for Windows XP SP2 and up has a sleek looking UI that might look too modern compared to the gradients of old XP along with top-notch protection and no noticeable performance hit.

Panda‘s offering differs from many of its competitors by running scans in the cloud, meaning users will not have to deal with daily updates.

Its great protection scores also mean that despite the cloud nature of the program, it will still keep you protected.

In fact, since Panda‘s antivirus software does run in the cloud, it always keeps itself up to date instead of nagging the user to download update files one or more times per day.

This ability to keep virus definitions up to date with no user interaction or knowledge just means better protection and more up-to-date protection for you without sacrificing the performance of your own system.

Unfortunately, Panda Cloud Free has given a few false-positive warnings in the past. This helped keep it out of the top spot.

However, Panda remains a good antivirus. If the free version doesn’t have enough features, we suggest you to buy the paid version.

Kaspersky Lab has had a great reputation for a while now, and it will certainly not be a bad choice to secure your Windows XP SP3 machine from viruses.

With similar scores given from AV-TEST, Kaspersky‘s reputation along with low system requirements helped place it up to the number two spot.

Not taxing a computer too much to keep it protected is a big deal for Windows XP machines since many of them are underpowered.

Kaspersky only requires an 800MHz processor, 512MB of available RAM, and a minuscule 480MB of disk space, giving room to breathe on most machines, especially older Windows XP 32-bit ones that tend to have 1GB of RAM and slower processors.

Avast is the official home security software for Windows XP, another reason why 435 million users trust it.

AV Comparatives claims Avast to be the least impacting antivirus for PC performance. In addition, it comes with advanced cleaning and optimization features for your PC to further improve its performance.

Avast Free Antivirus protects users in Windows XP through regular updates. However, software updates (including new features, hotfixes, or support) are no longer available due to the fact that Microsoft has stopped publishing security updates for this version.
