Are you a Windows Vista user worried about the choice of antivirus to use? This post is meant for you.

Vista might be one of the oldest Windows OSs but it is still relevant. Meanwhile, there are several antivirus software packs suitable for it.

Keep in mind Vista is no longer supported by Microsoft for some years now. What’s more, given the evolution of the Windows operating systems, antivirus developers have also adapted.

Thus, limited applications emerged and we are going to exploit them below. Without further ado, check out the best antivirus for Windows Vista that you can still use today.

How old is Windows Vista?

Windows Vista has been around for well over a decade. It was initially released to the commercial public in January 2007.

The main new features that Vista brought were a more modern graphical interface, the Windows Search function, and new multimedia tools.

Despite the fact that it was met with a mixed reception and is up to this day one of the most criticized versions of Windows, there are still a significant number of people that still use it today.

Can I still use Windows Vista in 2022?

Despite the fact that Windows Vista has been discontinued and Microsoft ended its support for the OS in 2017, a considerable number of people keep using it.

The operating system and its built-in apps do no longer get updates, so it’s important to address whether it’s capable to provide a good and secure user experience or if it’s best it stays retired.

We must mention that a discontinued OS is never going to be as secure as an up-to-date one. It does not comply with current security requirements which makes it a lot more vulnerable than its upgraded counterparts.

There are, however, a lot of software companies that still develop apps that are compatible with the OS. Most notably, there are several worthwhile antivirus tools that you can install today to protect your Windows Vista PC.

If you want to keep your Vista PC secure, installing a third-party AV is more of a requirement than an option. The built-in Windows Defender is no longer updated, hence it’s incapable to handle current viruses.

It is also important to note that other vital applications such as browsers or email clients still offer Windows Vista compatible applications and it’s recommended you get them as well as they too contribute to good overall security and privacy.

That being said, the number of apps that support Windows Vista is decreasing. Of course, you can always find older versions but they are certainly not secure, not to mention the fact that many of them are only available for download on suspicious websites.

So while it’s still possible to get and use the operating system, finding secure apps that are compliant with today’s needs can get tedious. To make this matter easier, keep on reading to see your best antivirus options.

What antivirus works with Windows Vista?

Windows Vista users can benefit from updated security support from companies such as ESET, Kaspersky, and other prominent cybersecurity giants mentioned below.

The operating system also integrates Windows Defender just like newer versions of Windows. It is not enough, but you can keep it enabled and combine it with a third-party app for enhanced protection.

You can also download older versions of your favorite antivirus. We do however advise you to do this with caution as they may not offer the best protection against newer threats. If you decide to go for this option, please only download them from trusted, official websites.

What is the best antivirus for Windows Vista?

When picking your antivirus for Windows Vista it’s important to first and foremost consider compatibility. Once that’s established, make sure your AV is able to detect and block today’s security threats.

Another vital thing to consider is online security. It’s highly recommended you get an AV with a powerful firewall and real-time detection to overcome any security shortcomings that may appear due to outdated browsers and other similar issues.

Taking all these into account, we came up with the following antivirus list that includes both free and paid options that are capable to protect your Windows Vista PC against current security threats:

  1. ESET NOD32
  2. Panda Dome
  3. Kaspersky Internet Security
  4. AVG Internet Security
  5. Avira
  6. Avast Free Antivirus
  7. Webroot Antivirus

Make sure to read the full list as the following antiviruses vary in features. Some include VPNs, while others have gaming modes and removable media scanners, see which best fits your needs.

ESET is a PC protection company that has been in operation for about two decades now. The ESET NOD32 is an antivirus software still compatible with Windows Vita and uses very little of your computer’s resources.

We must however mention that all new ESET products use the SHA-2 hashing algorithms, whilst Windows Vista uses SHA-1 algorithms. This incompatibility can lead to some issues, but there are ways to solve them.

If you already have ESET installed on your Windows Vista, the antivirus will automatically update to the newest release if that option is enabled.

You should also have no issues installing it. The problem is that some features like Web and Email protection may not work.

According to ESET’s website, the current version of the AV only offers limited support for Windows Vista, which will end in November 2022. They offer older releases of the antivirus, so you can try to download those.

Another option that has worked for some users is to try to upgrade your Windows Vista hashing algorithms to SHA-2. Microsoft offers upgrade files for x86-based and x-64-based versions of Windows Vista in the Microsoft Download Center. 

Let’s quickly look at its key features:

  • User-friendly interface
  • Comprehensive protection against spyware, viruses, worms, adware, and rootkits
  • Protection for removable media such as external hard drives and USB flash drives
  • Thorough scanning followed by a report of the status of your PC’s security is provided

Does Windows Vista have Internet Security?

Can Windows Vista be upgraded to Windows 11?

To upgrade your Windows Vista computer to Windows 11 you will have to resort to a clean install. Whilst Windows 10 users can upgrade directly from the Settings app, this option is not available in Vista.

Afterward, you can uninstall your current version of the operating system and then install Windows 11 on your PC.

You also have the option to upgrade the OS step by step. You can upgrade to Windows 7 from the Settings, then upgrade your Windows 7 OS to Windows 10, and finally to Windows 11.
