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.

Although XP is more vulnerable in principle owing to its age, in practice, most hijackers are script kids using off-the-shelf software.

That software tends to target the most renowned operating systems, so with XP using single digits, there aren’t many people building attacks against it.

Advantages and disadvantages of using Windows XP

Is Windows XP still fully operational? Yes, it is, but it is riskier to use. To assist you, we will outline several techniques that will keep Windows XP safe for a long time.

✔️Pros:

Windows XP hasn’t lost all of its benefits. Even if there are a few, we are confident that it has some minor or major flaws.

  • A 1-gigahertz CPU with 1 gigabyte of RAM is all that is needed for a 32-bit system and 2 gigabytes of RAM for a 64-bit system.

  • System Restore and Device Driver Rollback.
  • Remote Desktop and Remote Assistance are both supported.
  • Mode of Application Compatibility.

  • With the Professional version of Windows XP, you can configure a computer to run with two processors; allowing high processing speed equipment.
  • Windows system security is extremely weak, making it vulnerable to viruses and worms.
  • The lack of a Java Virtual Machine is impetuous.

  • The screen can get crowded due to malware attacks.
  • XP inherited the blue screen of death, and new hardware is not available for this edition.

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.

Why do I need a lightweight antivirus for Windows XP?

If you are one of those Internet users of Windows XP, getting a reputable third-party antivirus software should be a top priority.

Even if our computer has limited capabilities or is relatively old, you may install a lightweight antivirus that does not consume a lot of system resources.

Even regular virus definition downloads from traditional antivirus packages might be too much for the limited storage space on a Windows XP PC.

A lightweight antivirus tool with cloud protection can provide comprehensive security while using few resources and leaving a small data trace.

We tested the best lightweight antivirus applications for outdated or low-end devices in this list to ensure appropriate security without bothersome delays or freezes.

Some of these tools are free, while others come with a price tag. Read on to learn how each of these antivirus solutions can protect your Windows XP PC.

What to look for in antivirus for Windows XP?

Most antivirus solutions for Windows XP give full functionality in trial mode for a limited time, whereas a free version removes certain functions and makes the free product available for a year or longer.

We believe that it is as much about the operating system as it is about system resources such as processor type and speed, as well as memory.

If you don’t have enough capacity, disk space might be an issue. Because you can only install one real-time AV solution, you’re obviously better off selecting one with a high protection rating.

But you shouldn’t stop there if you’re browsing on your XP computer, because the chances are heavily stacked against you.

To keep secure, you should perform periodic double-checks by scanning with any of the on-demand malware-removal solutions listed below.

Supplementing your anti-virus program with anti-malware tools provides the highest level of security for the vulnerable Windows XP.

You should also be aware of the PC resources impacted by your antivirus of choice to assure high performance on your computer.

This is why we classified each antivirus from this article in order to inform you about full scanning CPU usage and quick scanning CPU usage.

Can you still download Windows XP Service Pack 3?

You may launch Windows Update by selecting the Windows Update icon in your Start menu to install Windows XP Service Pack 3. Windows XP SP3 should be one of the available download and installation choices.

Although Windows XP Service Pack 3 may still be obtained via the Windows Update Catalog, the media for Windows XP is no longer available for download from Microsoft because it is no longer supported.

Is Windows XP Service Pack 3 32 bit or 64 bit?

There is no Service Pack 3 for Windows XP 64-Bit, only a 32-bit with the final update.

Windows XP Service Pack 3 32-bit last update includes all previously released operating system upgrades. In addition to the things that have been available as separate downloads since Windows XP Service Pack 3 RC1, the current version offers further networking and security improvements.

If you’re seeking Windows XP x64, make careful to look for file hashes for Windows XP because they might be fake.

Still, Windows XP 32bit is best for old PC hardware that requires an OS with a user-friendly interface and low resource usage.

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.

With these tools and with our other guide posted throughout the entire article, we show that you can keep Windows XP forever.

However, if you think of updating your OS to the latest version, look at our selection with the best Windows 11 antiviruses.
