Below, we dive into in-depth reviews of the best free antivirus software that can provide basic protection without a subscription. However, you can also upgrade to their premium version for more comprehensive protection.
1. Avira Free Security: Best free antivirus for Windows
Features at a glance:
- Real-time malware protection
- Ransomware protection
- Scans for privacy and performance issues
- Lightweight and fast
Avira Free Security is a lightweight, award-winning antivirus suite that has proved to be effective since its launch in the early 2000s. For a free security suite, Avira has a lot to offer, and it scores highly on detecting and preventing various types of malware that are prevalent today.
In our tests, it especially stood out for protecting against ransomware. Avira Free Security also did a fantastic job at offering virus protection against financial malware that’s designed to steal banking information and money from victims’ accounts.
A key component of a good antivirus is real-time protection. Avira Free Security SmartScan offers preventive antivirus protection by constantly running in the background, scanning for malware in files, incoming connections, external storage, and much more. It also scans for privacy and performance issues.
However, the free version lacks security features available in the paid software version, such as web protection through add-ons for major browsers. This feature blocks blacklisted websites, phishing sites, and ads. The suite also lacks Avira Mail Protection, which protects your unsecured, non-encrypted email traffic. Check out our full Avira antivirus review for more information.
2. Bitdefender Free Antivirus: Most user-friendly free antivirus
Features at a glance:
- Real-time malware defense
- Easy to use, beginner-friendly software
- Adapts to your hardware and software configuration
Bitdefender antivirus free edition has come back with a bang! The free version was phased out in 2021, but now, it’s come back re-engineered from the ground up. Of course, like most free antivirus software, this free version is still limited to a handful of features compared to its premium version.
The new Bitdefender Antivirus protection free edition boasts a clean new interface that makes it easy to navigate. It works well on Windows PCs without hogging resources. Bitdefender Free offers complete real-time malware protection, ransomware threat detection, anti-phishing and anti-fraud measures, and web attack protection.
We also appreciate that it allows you to switch off advertising popups that upsell you the paid version. You can even switch off updates notifications. However, a downside to Bitdefender Free is that it lacks ransomware protection, unlike Avira Free Security.
3. Microsoft Defender: Free default antivirus for Windows
Features at a glance:
- Equipped with parental controls
- Built-in firewall
- Effective malware scanner
Microsoft Defender, previously known as Windows Defender, comes for free with Windows 10 and above. The free antivirus program has quickly proved to pack a punch among free antivirus protection software. However, based on August 2022 AV-Comparative tests results, the antivirus didn’t perform that well compared to other free antivirus programs on this list.
Microsoft Defender offers internet security and essential protection while gaming, downloading, and torrenting. This comes by default in Microsoft Edge, but there’s an add-on for Chrome that offers the same level of protection for Chrome users.
What we like about Microsoft Defender is that it runs quietly in the background without bombarding you with popups and annoying offers that compel you to upgrade to the premium version. It offers live and solid protection, and it’s quite effective against a wide range of malware. One of the reasons for this is it’s frequently updated, hence keeping it abreast of the latest threats.
This scanner also helps you protect your kids online thanks to its parental controls. You can monitor and limit their screen time habits, keep track of their digital life with active weekly reports, and choose what they can see and purchase for their devices.

Norton 360 is the best antivirus for PC gamers due to its Game Optimizer feature which eliminates FPS lags and boosts your games’ power.

Features at a glance:
- Built-in VPN
- Awarded 100% detection and protection rate by SE Labs
- Firewall
- Webcam protection
- Ransomware shield
- Blocks online trackers
Avast has long been one of the best antivirus software for Windows. This is mainly due to its seamless integration with Windows PCs and its top-notch vulnerability and malware detection system. In AV comparatives tests results, Avast scored an impressive 100% online protection rate, 98.8 online detection rate, and 93.9 offline detection rate.
Avast has different types of scans, ranging from quick scans, full system scans, boot time scans, and custom scans. They satisfy different needs but collectively work together to root out any potentially dangerous programs wherever they are hiding in your system.
This antivirus program can protect you from dangerous public Wi-Fi access points. It also blocks off phishing websites from tricking you into handing over your sensitive information. Avast reinforces this with its SecureLine VPN, which will offer identity protection online.
Avast has had its scandals in the past, such as getting caught selling user data to a third party. However, it cleaned up its act and it’s back to doing what it does best, which is providing some of the best security for users.

4. Surfshark One: Best all-in-one security solution for Windows
Features at a glance:
- Includes award-winning VPN
- Real-time protection
- Device scanning
- Transparent privacy policy
- Great customer service
Unlike most antivirus software companies that started by offering antivirus programs and then including a VPN service, Surfshark went the opposite route. Surfshark started as a VPN service and quickly became one of the best VPN services in the world. After that, it entered the antivirus software industry and bundled both its VPN and antivirus program into the Surfshark One Security Suite.
Even though the antivirus can’t yet compete with older antivirus programs, it’s shown lots of potential. In our tests, we downloaded a malware sample from European Institute for Computer Antivirus Research (EICAR), and the antivirus caught it in a heartbeat. However, it’s good to note that Surfshark One is not yet featured in any independent lab tests.
Together with its VPN, you can be assured of safety and security while browsing online. A strict no-logs policy ensures Surfshark does not store your data, which means it can’t sell any of your data at all. You can read our comprehensive Surfshark One review to learn more.
They also have a 30-day money-back guarantee trial that you can use to test the full capabilities of the software.
5. Malwarebytes: Best anti-malware scanner for Windows
Features at a glance:
- Exploit and vulnerability protection
- Scored 99.99 detection rate on Windows
- Real-time malware protection
- Browser guard
- Three scan modes
- Minimal CPU usage
Malwarebytes is hands down one of the best PC antivirus and malware scanners available today. AV-Comparatives recently tested Malwarebytes on 725 malware samples that range from trojans to spyware. The results were a 99.9% detection rate on Windows, as Malwarebytes detected 724 of the samples. However, there were also a lot of false positives that led the lab to downgrade the software’s score.
On the plus side, this antivirus software’s real-time protection is a force to be reckoned with. It offers multiple layers of protection that range from ransomware to exploits and potentially unwanted programs. In addition, the Browser Guard feature protects against adware, trackers, and phishing websites. It works well with major browsers like Google Chrome, Microsoft Edge, and Firefox.
Malwarebytes VPN is a virtual private network that’s included in its premium antivirus suite, although it’s not as good as other VPNs out there. For example, it has a meager 400 server locations in 30 countries, compared to NordVPN, which has 5,400 servers in 60 countries.
On top of that, Malwarebytes has an unfavorable log policy, in that it stores user data such as device ID, browser type, internet service provider, and geographic location.
All in all, Malwarebytes is an industry titan when it comes to malware protection. It’s always topping our charts and those of independent antivirus testing labs.

Do You Need Antivirus Software?
Cyber-criminals are getting craftier at inventing sneaky malware that can affect users in different ways, from viruses to worms, trojans, ransomware, adware, spyware, and much more.
These pieces of malicious software can cause a wide range of damage when they get into your device.
To make it worse, malware can be transmitted in various ways as well, such as:
- Email attachments
- A friend’s USB device
- Malicious link in an email
- A trusted website that’s been hacked and used to transmit malware
As you can see, it’s hard to keep track of where the next online threat will come from, and it’s even harder to get rid of it once it infects your device and attaches itself to critical system files.
Here’s a quick breakdown of the common types of malware and their effects on devices.
| Malware | Effects |
|---|---|
| Trojan | Trojans masquerade as legitimate software. Its effects include deleting or modifying data, stealing data, installing additional malware, and disrupting system performance. |
| Spyware | Spyware continuously collects almost any type of data, including personal information like internet surfing habits, user logins, and bank or credit account information. |
| Adware | Adware clutters your device with pop-up ads, slows down your browsing speed, changes browser homepage and search results, and affects your system’s performance. |
| Ransomware | Ransomware locks up and encrypts all your files until you pay the demanded hefty ransom. The effects can be adverse for individuals and businesses if the files are critical. |
| Keyloggers | Keyloggers record your keystrokes and send them to a remote server. They’ve been designed to recognize login information, credit card numbers, and much more. |
To stay safe and browse the internet safely without worrying about online threats, we advise using an antivirus. Antivirus products will continuously run in the background and scan all incoming connections, websites you visit, attachments, files from an external device, links in emails, and so on.
Antivirus programs get constant updates to keep them abreast of the latest threats being released. This ensures your safety against new and old malware infections alike.
Are Free Antivirus Programs Safe?
Free antivirus programs come with several concerns. For example, various programs pose as free antivirus software but are malware. Once installed, they raise an alarm on non-existent infections and demand you to pay to remove them.
Other concerns include:
- They will bombard you with pop-ups trying to compel you to upgrade to the paid version.
- They only give you partial protection from the various online threats users face today.
- They are reactive most of the time, and only take action when the infection has occurred.
- Some have been caught selling user data.
With that said, when it comes to something as crucial as antivirus software and what it does, it’s best to weigh the risks involved. Is it worth forgoing a couple of bucks a month and risking identity theft protection, stolen banking information, data loss, a system crash, and so much more?
Why Kaspersky Antivirus Did Not Make the List
Kaspersky Antivirus has topped our list of the best PC antivirus for years. In 2022, however, Kaspersky was reported to be liaising with the Russian government. The US and German authorities have rang the alarm for years on Kaspersky antivirus and instructed their agencies and officials to not use the software.
In one case, for almost two months in 2014, servers belonging to Moscow-based Kaspersky Lab received confidential National Security Agency materials from a poorly secured computer located in the United States. The servers stored the files, most likely in violation of US laws.
Most people say this could be government propaganda. Kaspersky has also denied all accusations. However, the Ukraine war revealed the connection between Kaspersky and the Kremlin. The antivirus was caught protecting Russian military web assets from DDoS attacks using its servers.
Some may argue that Kaspersky antivirus only siphons user data from high-profile targets such as government agencies and the elite. However, even if it’s true, it still raises a concern about what the objectives of the software are. Consider that an antivirus scanner is installed deep into your system and can access anything and everything within your device. For these reasons, we’ve halted featuring Kaspersky in our reviews.
How You Should Pick the Best Antivirus For PC
1. Price
Most antivirus software usually have three paid tiers: a basic, midrange, and premium plan. Each tier has different features for different prices. The features, as well as the price, increase as one moves from a basic to a premium plan. You can expect to pay for annual subscriptions within the following ranges:
- Basic plans range from $40 to 60 (Supports one device)
- Midrange plans range from $60 to 80 (Multi-device support)
- Premium plans range from $80 to 150 (Unlimited devices support)
The majority of antivirus software plans offer a discounted price for the first year, then the normal price takes effect from the second year. For instance, Avira Prime starts at $47.99 for the first year and then automatically renews at $79.99/year.
A good rule of thumb is to go through the different tiers and take note of their prices after the first year, then decide on the security software that works for you.
2. Level of protection
Different types of antivirus software come with different capabilities. For example, even the best free antivirus software only offers basic security with a few additional features at best. However, in a world that’s riddled with malware and other threats, basic protection is not enough.
PC users need maximum protection against all types of malware, webcam hacking, online tracking, phishing, identity theft, and more. This level of protection can only be offered by reputable and comprehensive antivirus tools such as Norton 360.
3. Parental controls
The internet is beneficial to kids, but it also contains a lot of content that’s not good for them. Good antivirus software such as those listed here come equipped with parental controls. You can monitor and control your kid’s activities online and ensure their safety.
4. Great customer support
Your antivirus service of choice should have knowledgeable and reliable customer support. Considering the crucial role an antivirus suite plays in our lives. Customer support must be reliable in case of a breach, infection, or performance issues caused by the program.
