One of the most recommended free antivirus software is Bitdefender, which is also one of the fastest free antivirus scanning programs, with minimal impact on your computer's performance. He consistently ranks top according to the results of various antivirus tests.
While the free version doesn't offer all the extras as the paid version, Bitdefender Free covers the basics very well.

Phishing Protection
Automatic scanning
Behavioral based malware detection (e.g. analyzing potential process activities before doing anything)
Digital Safe File safe, which encrypts any file you want to keep safe and prevents any changes

Low system impact (does not slow down the computer while it is running)
What we don't like:
Not many advanced options
Slow initial scan
Unable to schedule or adjust scan
There are no business options (only for home use)
Below-average zero-day attack protection (protecting from known threats, but not yet able to deal with new and unknown threats)
Reasons to switch to the paid version:
Online banking protection
Permanent file destroyer
Password manager
24 hour technical support with FREE telephone calls
Advanced ransomware protection
Firewall
Parental control devices
Most suitable for:
Bitdefender is the answer for users who only want an antivirus to install it. It's a powerful antivirus that runs on autopilot, and in general only requires a little user intervention and adds a little extra "bloatware".
ZoneAlarm is considered the best free antivirus for web surfers, because many of its features are aimed at online protection. It also comes with a solid default firewall, easy to install and configure.
Features offered:
Anti-malware scanner
Default personal firewall
Identity protection
Online file backup
Default web security and privacy toolbar

Overall, ZoneAlarm performs well, but has many additional features that, in our opinion, are unnecessary. We would rank it as a slightly extraordinary antivirus, if not for its excellent firewall protection.
If you surf the web a lot and worry about your safety, ZoneAlarm is the right choice for you.
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.
This complete and versatile antivirus also has many additional features to make it even more interesting.
Features offered:
Detection of ransomware
Phishing Protection
Password manager
Free Phantom Avira VPN (1GB / month)

Premium mobile application
VIP customer support
Most suitable for:
The new and better Avira free antivirus is a fantastic versatile solution because it has many powerful features that you normally don't get in free software. However, it is equipped with advertisements and pop-ups, so for a long-term solution, maybe for you the paid version is not too annoying.
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).
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.
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.
Features offered:
Real-time protection
Phishing Protection

There is no feature to schedule a scan
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
Most suitable for:
Sophos is a sophisticated family antivirus because it protects up to three devices. Houses with several computers and children will enjoy the benefits of parental control and multi-PC protection on Sophos....
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
What we like:
Compatible with a number of platforms, including Windows 7, 8, 8.1 and 10 as well as Windows Vista and XP SP3. He also runs on Mac and Android devices
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.
