As we near the end of 2022 we look at the current best antivirus software for popular platforms, why they are the best, and why you should get them.

Avira, a great free Antivirus

Avira has been around a long time with its free antivirus version of the larger protection suite. It had its ups and downs but the latest versions are really great. With high-speed scans and low system impact, Avira antivirus is really one of the best free antivirus software currently on the market.

The software itself has also received UI & UX updates making it straightforward and easy to use. The virus scanning engine is the same as in paid version that ranks among the top engines in the world for this type of work. The package also gives you some great browser protection and a good firewall as well, there is really no excuse to skip on this if you want a free solution.

The only thing that we would say is not so great in Avira is reporting some false positives, sometimes even for MS updates, it is rare but it can happen.

Malwarebytes, a powerful Windows antivirus

Malwarebytes Premium is easy to use, simple antivirus solution that shies away from complicated UI, and simply put, it just works. Its scanning engine is well-known and places among the top and best in the world often finding some malware that other can miss.

Another great thing is its integration with Windows itself, it is one of the rare applications that can and will work incredibly well beside your typical Windows protection tools so you can have both of them running at the same time.

Installation and running are really simple and every typical PC user will find it as easy as walking in the park. On the other hand, sadly system impact is a little high and it will have issues running on lower-end systems due to its memory requirements.

Intego MAC Internet Security X9, the best Mac antivirus

Gone are the days when MAC had no virus issues, since MAC rose in popularity among the users, also rose the number of viruses and malware. The system itself has some great protection built it inside but for more security and better control of it, you will need a third-party dedicated solution.

Intego was made by Mac antivirus experts who have been building this kind of software last 25 years. The interface is easy to use and premade presets are really helpful, but the security suite can also be customized to fit your needs and desires.

Since this is only available as a security suite, you are getting a firewall and some other security tools along with your antivirus that will run as a part of it.

The bad side is that scans can sometimes run slow, most of the time they are OK in terms of speed but occasionally they can switch to slower speeds and impact scanning time to some annoying times. Also, there is no webcam protection nor VPN service included where others on this list have them.

Bitdefender mobile security: best Android protection

While protection is not only needed for your gaming or workstation, software suites that are dealing with mobile and tablet security exist. The best of them is the Bitdefender antivirus mobile suite. Low on system resources and low on performance impact with the really great virus detection rate Bitdefender is at the top of suites for your phone.

Consistent high virus detection packed with low battery impact is great but the suite comes with tons of other tools as well like browser security tools, email protection, and real-time link and notification protection.

The application will always scan each file and newly installed application in the background and alert and cut off any found threat. App itself is easy to install and use and most of the time it will do everything in the background for you but offer you customization if you need it.

The package also includes VPN and application lock that will let you protect the critical applications from being accessed as well as an online account scanner. Anti-theft and anti-loss tools, which allow you to find, remotely lock or wipe a stolen or lost device, add yet another layer of protection.

One thing that is missing from this great package is fraudulent call protection. Newer Android phones have this feature inside but it would be nice if Bitdefender had it as well.

Bitdefender, the best antivirus software

Now that we have covered specific cases of each platform, there is one player that has all of them covered and with a quality product, that player is BitDefender and it is great. Personally, this is my protection suite of choice and as I type this it is running in the background.

Bitdefender has it all, low system impact, as a matter of fact, it is one, if not, the lowest performance impact engine on the market currently and that is packed with a great and highly consistent virus & malware detection suite. Along with real-time malware protection, browser security, and anti-spam tools, you also get anti-phishing defenses, ransomware protection, and a strong firewall.

Bitdefender scores are very high in both the zero-day threat and real-world protection tests at AV-Test, an established organization that tests antivirus software. Despite being tested against tens of thousands of well-known and widespread malware threats, the software consistently achieves a 100% blocking rate.

The suite also comes with a restricted free VPN and with parental controls as well. Webcam and microphone protection are also included in the suite and on top of all, it has great pricing plans and constant discounts.

BitDefender is really a great package and it might sound too good, but after years and years of personally using it I have not had single malware or virus issue, the only thing that I would put as a negative is that system is severely slowed down when system scans are performed so be sure to run or schedule them when you are not using your computer. This, of course, can put some people off and I will admit it is a serious drawback but for me, the security of my workstation is more important than leaving the computer for 20 or so minutes in order to perform a full scan of the system.

Prompted For A Product Key – What Is It?

Some Windows 7 or Windows 8/8.1 users are having a hard time upgrading to Windows 10 as they are being prompted for a product key. By default, the Windows 10 operating system does not require a product key and users should not be prompted for one, given you upgraded your computer from an activated Windows 7 or Windows 8/8.1 license or from the Windows 10 Preview build.
