6. Avira Free Antivirus

Avira Free Antivirus

Now it offers a much smaller impact on system performance when running, and comes with a cleaner interface and is more user friendly.

What makes it stand out is its comprehensive range of protection against everything from rogue viruses to the most dangerous Trojans. In addition, the heuristic engine enables the detection of zero-day viruses (unknown threats) very well - a feature not commonly offered by free antivirus software.

7. AVG Antivirus Free

AVG Antivirus Free

AVG Technologies is one of the biggest names in the antivirus industry and we like it because it runs constantly in the background without requiring you to do anything.

As we mentioned above, the AVG company has recently joined the Avast developer. However, even though both programs enjoy the benefits of the collaboration, it seems that AVG is at a disadvantage. Although it is still a solid antivirus, AVG is much more like a "younger brother" when compared to Avast.

However, it might be possible for a company to consider combining AVG and Avast in one package, which will offer the best of both.

Features offered:
System optimizer tool
Block unsafe links and downloads
Real-time security updates
Spam and email filters (scan incoming emails to find threats)

What we like:
Compatible with Windows 7 SP1, 8 / 8.1, 10, Vista SP2, XP SP3 (other free versions available for Mac and Android)
Very good anti-malware performance, similar to Avast
Easy to adjust and configure
Little system impact (with options for scanning PC performance interruptions)
Specific detection (warning message that appropriately mentions a threat)

What we don't like:
Fewer useful features than Avast, for example there is no browser extension (using pop-up notifications instead)
Continue to advertise the paid version along with other unrelated features
The scan is slow (slows down more computers than other antivirus programs we tested)
Phishing protection is only average
Some threats that are quarantined are not permanently deleted from the system (risk of re-infection)

Reasons to switch to the paid version:
Additional ransomware protection
Webcam Protection
AntiVirus PRO for Android ™
Improved firewall

Most suitable for:
AVG is best suited for users who want a silent and quiet antivirus without a lot of frills. The program runs transparently in the background with little effect on system performance. If the job requires you to open various e-mail attachments, the e-mail attachment scanner will be very helpful.

Overall, AVG is a good solution for those who are just looking for basic malware protection without the need for advanced features, or anyone who wants to use it as a second layer of defense in addition to existing antivirus (AVG's passive mode allows it to run in the background along with other antivirus programs).

8. Kaspersky Free

Kaspersky Free

Although Kaspersky is one of the best-known antivirus brands on the market, because of a good conscience, we can no longer recommend their products because of speculation that their developers have helped state-sponsored hackers in Russia. Kaspersky has been banned by the US government, and a lot of evidence indicates that they have been mining consumer information and sending it to the Kremlin, so it becomes spyware.

9. Sophos Home Free

Sophos Home Free

Sophos is unique because it is optimized for multiple computers and runs using cloud-based protection, keeping system slowdown to a minimum. As a result, it works well for families who need protection on multiple computers.

What we like:

Simple and easy to use
Great network, server and end user protection
Little pop-up notifications

Comes with a free trial of the premium version for 30 days

Fewer options for more advanced users

Reasons to switch to the paid version:
Advanced ransomware protection
Protection for 10 more PCs
Banking protection
Advanced malware removal
Web and email filtering

10. Avast Free Antivirus

Avast Free Antivirus

Avast is one of the easiest antivirus software to use, and one of the few programs that offers strong protection against zero-day attacks - unknown new threats and antivirus programs themselves have not been programmed to capture them. Impressively, Avast has managed to protect 100% of zero-day attacks in recent tests.

Since Avast joined AVG Antivirus to provide a more robust solution, both have offered very comprehensive anti-malware and virus protection with a number of useful features that are usually only available through paid services.

Features offered:
Password manager
Anti-malware network scanner
A game mode that disables notifications and reduces system load when playing
Technology and behavior analysis customization

Strong zero-day malware protection
User friendly interface
Low system impact (runs without slowing down the system)

What we don't like:
Ads and notification pop-ups that often appear
Limited password manager features (no password reset or multifactor authentication)
Other software becomes slower to run when Avast runs
Lack of privacy or ransomware protection options
Anti-phishing protection is only average, so precautions are needed

Reasons to switch to the paid version:
Browser extension for phishing protection
Spam filter
Firewall
Ransomware protection
Automatic software update
Permanent file destroyer
Protection for more devices

Most suitable for:
In particular, Avast is the best choice for gamers, because it not only offers a special game mode but also provides a free Trojan removal tool which is great if you frequently download files and games.

However, even users other than gamers will like the best zero-day attack protection and additional features that exceed what other free antivirus programs offer. For those who want to avoid annoying pop-ups and advertisements, we recommend switching to the premier version as a more suitable long-term solution.
