Best cheap antivirus protection: comparison of software prices

What to consider when looking for the cheapest antivirus for laptop?

While free antivirus software can provide basic protection against cybersecurity threats, it often lacks advanced features like ransomware protection, phishing safeguards, or real-time updates. Besides, free versions can come with intrusive ads, limited support, or data privacy concerns, which may not be ideal for comprehensive security, to say the least. So, here are key considerations when choosing an affordable antivirus for a laptop:

• Essential features. Even a budget antivirus software should not make compromises on core protections like real-time scanning, malware and ransomware detection, and anti-phishing tools. These are the minimum defenses your system needs to stay secure.
• System performance impact. Look for antivirus programs that are lightweight and don’t slow down your laptop. There definitely are affordable options optimized to run smoothly without consuming excessive system resources.
• Multi-device protection. Look for an affordable antivirus package that offers coverage for more than one device. This way, you’ll make it even more cost-efficient.
• Subscription costs and renewal fees. Be aware of the initial discount versus renewal costs. Many budget antivirus options offer steep first-year discounts, but renewal prices may jump significantly, so check long-term pricing.
• Customer support. Even low-cost antivirus software should provide reliable customer support. Check if they offer support via chat, email, or phone in case you run into issues.
• Additional features. Consider whether the antivirus includes extras like a basic VPN, password manager, or firewall. These can add value to a cheap package and improve your overall cybersecurity.
• User-friendly interface. Make sure the software is easy to install and use, even for non-tech-savvy users. A good interface ensures you can manage your protection settings effectively without frustration.
• Privacy protection. Cheap antivirus should still respect your data privacy. Some budget options might come with bundled software that collects user data. So, choose one that has a transparent privacy policy and is well-respected in the industry.

I always consider these aspects when looking for affordable antivirus programs. Hopefully, these pointers will also help you select a valuable antivirus software.

Besides the core features, TotalAV also offers a trustworthy VPN service that adds an additional layer of cybersecurity. System tune-up tools and a clean-up feature declutter your device.

2. Norton Antivirus – cheapest antivirus for laptop in 2025

Norton Antivirus is another cheapest antivirus for laptops in 2025. The software performs exceedingly well with threat and malware detection and is also one of the cheapest, around with prices starting at a mere $2.50/month. However, Norton’s interface is not the most intuitive, making it a bit less beginner-friendly than my other choices.

Besides the mandatory security features, such as real-time protection and deep scans, Norton AV comes with a whole slew of additional features. There’s a reliable VPN service, parental controls, cloud backup, firewall, and data breach alerts. All of these features ensure your cybersecurity. As for their effectiveness, Norton AV malware detection rates kept a high score of 98% accuracy, while deep scan rates hovered at a solid 92%.

The top-tier plans also include dark web monitoring and a unique feature called LifeLock that guards users against identity theft.

3. Bitdefender – solid cheap antivirus with excellent security features

Bitdefender is a solid cheap antivirus that has well-functioning security features and offers extremely good plan pricings starting at just $9.99/year. And if you’re a fan of Linux OS, I have good news for you: Bitdefender is compatible with Linux.

As any reputable AV, Bitdefender has a very solid core feature pack including deep system scans, ransomware protection, and real-time threat protection which, during testing, proved to be a very solid with 99% accuracy.

As for the additional features, Bitdefender offers parental controls, secure online banking, a highly-secure VPN for an additional layer of security. Lastly, there’s the unique feature called Scamio which is an AI-based chatbox that analyzes the legitimacy of any message or link you receive.

4. Malwarebytes – a fast low-cost antivirus with advanced malware and ransomware security

Malwarebytes is an affordable antivirus software for PC, perfect for those who prioritize speed, privacy, and a lightweight system impact. While its $3.75/month price tag is slightly higher than some cheap antivirus programs, its fast scans and AI-based threat detection make it a solid choice for security-conscious users.

Although Malwarebytes lacks some of the extra features found in other premium antivirus suites, its ad blocking and privacy protection are impressive, successfully blocking all elements on Canyoublockit.com. On top of that, it excels in identity protection and dark web monitoring – ideal for users who prioritize data security over traditional real-time malware blocking. For additional online anonymity, it also includes Privacy VPN in its Malwarebytes Plus and Ultimate plans, though it lacks third-party audits to verify its no-logs policy claims.

For on-demand scanning, Malwarebytes delivers solid performance, detecting 92% of malware samples in a full system scan, while keeping CPU usage low (4-48%). However, its real-time protection is more limited compared to some of the best antivirus software for Windows, making it better suited for users who rely on manual scans and proactive security measures.

Lastly, Malwarebytes supports Windows, macOS, Android, and iOS (with limitations). So, for those seeking a cheap PC antivirus with AI-enhanced malware detection, dark web monitoring, and strong ad-blocking features, Malwarebytes is a solid budget-friendly option. Plus, you can try it risk-free with a 14-day free trial and a 60-day money-back guarantee.

5. Surfshark Antivirus – affordable antivirus with excellent security features

Surfshark Antivirus is a very affordable antivirus with one of the strongest security features around, with a starting price of only $2.49/month. Besides its stellar cybersecurity feats, the software probably has the sleekest-looking apps that are easy to navigate and use even if you’ve never used an AV before.

Naturally, Surshark Antivirus comes with the mandatory security features, such as real-time protection, which operates at a nice 90% accuracy, deep system scans, and a sure-shot ad-block called CleanWeb that stops all malicious popups before you even see them.

Lastly, Surfshark’s malware database is updated every 3 hours, so you can rest assured that no zero-day viruses will breach the protection layer.

Surshark Antivirus is compatible with Windows, MacOS, Android, and iOS, and you can safely try it out, knowing that there’s a 30-day money-back guarantee.

Affordable antivirus software virus detection test

A good antivirus software, no matter the price, should be plenty capable of detecting malware. So, before submitting my recommendations on the best cheap antivirus, I did some in-house testing on their real-time protection accuracy and deep-scan capabilities. I performed my tests on a Lenovo ThinkPad T14s Gen2 device (AMD Ryzen 5 PRO 5650U processor, 16 GB RAM, 256 GB SSD) with the Windows 11 Pro operating system installed.

For the real-time protection accuracy tests, I downloaded unzipped malware files to see if the software would react properly. For the deep-scan capability test, I stored malware samples in my computer and evaluated whether the AV caught them all. Then, I checked my results with those of independent test labs, such as AV-Test Institute, SE-Labs, and AV Comparatives.

So, here’s how each antivirus performed in my tests:

As you can see, all of my choices performed at above 89% accuracy rates, which is more than acceptable for an AV to be called near-impenetrable. However, TotalAV stood out of the crowd with the best scores overall, which makes it the best and cheapest antivirus software.

Why not to use a free antivirus?

People often look for a free or very cheap antivirus, which might not actually provide complete protection for your data and device. Free and very cheap antiviruses often lack some of the core security features, like ransomware protection, phishing safeguards, or real-time updates, and it puts your security at risk. In addition to that, free antiviruses still need to make money somehow, and your data might be the source of their income. Lastly, some free or very cheap antivirus software can even be infested with malware or trackers of its own, doing the exact opposite job an AV should.

If you want my advice on which specific software not to choose, here are some I have personally blacklisted:

• Kaspersky. Kaspersky is a Russian-based company, and their software, come September 2024, is banned from operating in the US due to alleged spying accusations. If that was your top AV choice, here are my recommendations on the best Kaspersky alternatives.
• Avast free and AVG free. While both are well-known companies, their free version lacks essential security features, which puts your data at risk.
• PC Matic. This software uses a unique white-list approach to malware detection, and although on paper it looks good, its actual detection rates are quite subpar. The software is also known to generate a liberal amount of false positives, which often interfere with normal device use.
• Trend Micro. Although it is a good software, the free and basic plans lack more advanced security features such as a firewall and comprehensive malware detection.

Instead of choosing any of these programs, try out one of my suggestions and see if it comes up to your standards.

How to get the best value antivirus software cheaply?

The easiest way to get an affordable antivirus is to purchase the software license directly from a cheap software vendor. However, that is not the way to get a value antivirus software cheaply, and here are your other options:

1. Take advantage of seasonal promotions. Same as with any other item, antivirus software often falls under the seasonal sale bracket. Expect the prices of your favorite software to drop on Black Friday, during the holiday season, before the start of the student school year, and on other notable dates. While it requires a bit of manual monitoring, grabbing such a deal might save you a good chunk of money.
2. Opt for multi-year subscriptions. While this might sound daunting at first, getting a 2, 3, or even longer AV subscription is always cheaper than paying month-to-month. And if you’re still a bit wary of committing in such a way, remember that most companies have a 30-day money-back guarantee, or in Norton AV’s case, even a 60-day one.
3. Use free trial periods to test the software. As I briefly mentioned before, almost all respectable AV software comes with a money-back guarantee or free trials. It’s the perfect way to test out if the software works for you before you commit.
4. Look for bundle offers. Why purchase an AV and a VPN software separately, when there are money-saving bundles like the Surfhark One, where you get the whole security package in one. Of course, you might be looking for some other thing, like a password manager to add to your security package, but those can also often be found together with an AV in a budget-friendly package.
5. Explore referral programs. AV software companies often have referral programs. It either works by you referring their product to someone else or vice versa. Either way, you’ll be getting a nice discount for it, so why not search for antivirus software that has a referral program, such as TotalAV?

Final thoughts

Balancing affordability and effective cybersecurity is key when choosing reliable, secure, and inexpensive antivirus software. While free options may seem appealing to many, they often lack essential features and could compromise your security. So, it's definitely worth investing in a budget-friendly solution that offers robust protection instead.

Among my top 5 contenders, TotalAV stands out as the best overall choice for cheap antivirus for PC. It offers strong malware detection, real-time protection, and additional features like a VPN. All of it comes at a highly competitive price that won’t hurt your wallet. You can try this software for free with a 30-day money-back guarantee before committing to it full-time.
