An antivirus program needs to be fast, efficient, and cost-effective, and this one has them all.

More than 10 years have passed after Windows 7 was first introduced and it’s still one of the most popular Windows versions out there.

Do I need antivirus on Windows 7? Yes, you do. The sudden emergence of the large-scale ransomware outbreak showed us some undeniable security loopholes in Microsoft’s fan favorite.

Basically, a lot of users put aside the fact that the outdated Security Essentials can deal with an abundance of the ever-growing virus threat.

That’s exactly where the third-party antivirus is, maybe not the subtlest, but certainly the preferred solution.

Now, most professional users or corporations will turn to paid security solutions in order to protect every software inch of their network and individual PCs.

However, a standard home user who roams freely through the Internet isn’t in a particular urge to spend his or her hard-earned money on an antivirus, without knowing if it suits his needs.

This is where our antivirus solutions come in, which you can try for free for 30 days, or for which you have a 30-day money-back guarantee before you should buy their amazing full services.

But before we dive in, keep in mind that Microsoft has officially ended Windows 7 support in January 2020. This means that installing a reliable antivirus solution on your Windows 7 computer is of paramount importance.

So, if you’re looking for the best antivirus to protect your PC and add some bonus features to your daily workflow, too, make sure to check out the list below.

Avast Free Antivirus

The 3 words to describe Avast‘s free edition is: simple, compact, and useful. Most antivirus developers create too much of a gap between the paid and free versions. That’s not the case with the Avast Free Antivirus.

Yes, you’ll lack some of the useful premium features, but the essentials are still there: real-time protection, web-based protection, and deep and thorough scanning and detection capabilities.

In addition, you’ll have the following secondary features and a few quirky tools at your disposal:

  • Phishing protection
  • Password manager which you can sync on multiple devices (not perfect, but since it’s free…)
  • Wi-Fi Inspector to keep your network safe.
  • Rescue Disk feature for restoring the system.
  • Software Updater that looks for outdated programs installed on your PC.
  • Browser Add-on integration for security while you’re surfing the interweb.
  • SafePrice add-on for the best prices while shopping online.

Protection-wise, its virus base is enormous and the detection rates are slightly above average. When it comes to drawbacks (and every product has those, too), the Avast Free Antivirus’s CPU activity can sometimes be an issue.

Luckily, you can restrain that by enabling the Game Mode within the Avast Control Panel.

Avira Antivirus

Avira emerged from a small alternative antivirus solution to a full treat for users that favor free antimalware tools.

It’s simple to use and configure but packs valuable features in regards to anti-malware on-demand scans and real-time protection.

It checks most of the boxes in those regards but excels in a variety of additional features you can download.

With those, you can create your own anti-malware suite on multiple platforms and customize it by your own choice.

Some notable features that you can get with the free version of the antivirus:

  • Real-time protection and browser safety;
  • Password manager;
  • Avira Phantom VPN – free VPN service limited to 1GB. You’ll need to pay in order to stretch the mileage.
  • One-click optimization tools.

There’s more and you can easily find them once you install this nifty little antimalware tool.

However, even though it does everything it’s supposed to do, Avira surely does take some time while scanning or updating, which might be a blocker for some.

You can compare these with the premium features of the paid versions and choose the plan that fits you best.

Bitdefender Internet Security

best antivirus windows 7

While we’re at essentials, we can’t overlook the Bitdefender which is, arguably, one of the best free antivirus programs you can get for Windows 7.

But, there’s a catch: the amazing virus detection and protection features are all you’ll get. No additional features, no multi-structural protection, password managers, etc.

Most of the antivirus software nowadays evolved into multi-functional hubs for everything even remotely related to PC security. Not the free version of Bitdefender.

With the free edition of the software, you’ll get the ultimate anti-malware and anti-phishing protection traits. For other built-in tools and bonus features, you’ll need to purchase the premium version.

Basically, premium protection for free with top results from various independent testing labs in regards to malware detection and antiphishing protection. And that’s where it excels the most.

If you’re accustomed to uncluttered antivirus solutions, with special emphasis on simplicity and real-time protection from malware and fraudulent sites, look no further than Bitdefender‘s Free Edition.

The highest ratings in various security categories speak for themselves.

AVG Internet Security

good antivirus for windows 7

A classic in the antivirus software industry, AVG got redesigned and now, besides the exquisite protection features, Windows 7 users can experience better-suited looks, as well.

Various security experts place AVG just below Bitdefender in regards to antimalware protection. It slightly fails in the anti-phishing department, but that’s just one minor flaw we can single out.

AVG tracks unknown and suspicious applications and prevents them from running until it’s certain that they won’t harm your PC in any way, and then and just then, enables them to start.

Besides the great depth of virus base and ferocious dealing with infections, AVG, as well as the majority of modern-day antivirus solutions, comes with a lot of auxiliary tools.

The first that crosses our mind is Web TuneUp utility that works as an add-on for basically all browsers. With Web TuneUp, you can browse safely and with your privacy unscathed.

The multitude of protective features indeed requires some tweaking, but with the redesigned interface, the majority of newcomers will have an easy time.

antivirus for windows 7 OS

A lot of security experts either advise you to keep your hands off third-party solutions or not to use them as real-time protection services. Especially on Windows 10.

However, security isn’t something you should threat lightly and we’re talking about Windows 7.

So, if you’re not keen to use an active software solution but rather a specialized malware and anti – AdWare tool, consider Malwarebytes tools as the best suited for the job.

Malwarebytes Anti-Malware and AdwCleaner are 2 different programs that thrive in different categories.

The first is, in its free form, a simple but nonetheless effective tool with a single purpose: locating and exterminating malware infections.

You’ll just need to download it and run it manually since the free version lacks real-time protection.

The detection rates are probably the best in the class and, taking into consideration the precision of the paid version, this free-of-charge program is not far behind.

The second program addresses the most popular contemporary malware and that’s AdWare.

AdWare isn’t only about annoying ads that bombard you, but also the following viruses that come with it and bring much more problems.

Now, even though most users pay close attention while installing programs or blocking annoying pop-ups, the unwanted software will find its place on your PC.

That’s where the AdWare Cleaner comes into play. Just run it and it will perform a deep scan and eliminate all AdWare-related programs and browser add-ons.

You can find the Malwarebytes Anti-malware tool on the main site. While for Malwarebytes AdWare Cleaner, navigate to this web address.

For maximum protection, we recommend the paid version which includes more features.



In a world where an old OS is a sitting duck for cyber-attacks, software such as Malwarebytes can be really helpful!

Not sure about most of these… If you really want to browse securely, you need to pay for a VPN. ExpressVPN, Nord, PIA are all great options — each provides secure, private browsing with encrypting your network. Free VPNs can’t do that.
