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. 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.

Is antivirus necessary for Windows XP?
It is very important since the operating system has gone unsupported for over 6 years now. But before that, you should make sure you are as up-to-date as possible.
Because Windows XP lacks a built-in defender like its successors, it is highly recommended that you use an antivirus optimized for it, just be on the safe side when browsing the internet.
Instead, you’d have to download Microsoft Security Essentials for first-party protection, which is both obsolete and only provides a very basic level of security.
To secure your Windows XP PC, we strongly advise you to use a third-party antivirus if you want to keep using your Windows XP computers clear of hijacking attacks.

How do I deal with Windows XP security vulnerabilities?
As the number of unpatched and afflicted computers grows, so do the costs of recovering files or a damaged computer.
Our main concern is how a hacker would try to install malware on Windows XP systems. Once that goal is met, the attacker has essentially taken entire control of the system, with you having no idea what is going on.
And it is at this point that a WinXP PC that is no longer receiving security updates becomes particularly vulnerable.
What you should do to make Windows XP machines more secure is as follows:
- Ensure that all apps and security tools are up to date
- Replace Microsoft apps with open-source alternatives wherever possible
- Only use Google Chrome (or Mozilla Firefox) as the primary web browser
- Disable Vulnerable Browser Plugins Like Java, Flash Player, and Adobe Reader
- Firewalls, both hardware, and software should be used
- Make use of application and website whitelisting
