An antivirus is essential when we connect to the Internet to navigate without problems and without risk to our security. On the Internet we can find a lot of different antivirus. Some are free and offer basic protection, and others are paid and offer additional protection. However, the choice of a good antivirus must be vital for our computer, and that is that a bad choice can lead to performance and security problems.
Windows 10 installs Windows Defender by default, Microsoft’s default antivirus. Microsoft has been with its antivirus since Windows XP, however, it has always been one of the worst, if not the worst, in terms of security and performance.
Since the launch of Windows 10, Microsoft has taken its antivirus seriously and, in recent years, has improved so much that today it is the best antivirus for Windows 10 according to AV-Test tests, offering users the Better protection, best performance and best usability.
However, there are users who still do not trust Windows Defender and prefer to leave the security of their computers in the hands of other security solutions. There are always security firms that we can trust, such as Kaspersky, however, we must be careful when choosing other antivirus since some may pose more a threat to our security than a protection system.
The worst antivirus in terms of security
One of the worst antivirus that we can install on our computer is Malwarebytes Premium. Although this application is very good at detecting different types of malware, spyware and unwanted software, its behavior as “antivirus” leaves much to be desired with two points out of 6. As we can see, the results of the AV-Test tests have been catastrophic, it does not serve to protect our computer.
Another antivirus that we should avoid installing on our computer is Webroot SecureAnywhere. Although it is not as well known as Malwarebytes Premium, the security offered by this antivirus also leaves much to be desired with two other points out of 6. We cannot recommend it because it simply will not help.
Other antivirus that have also been below the average protection have been, for example, BullGuard Internet Security , eScan Internet Security Suite and PC Matic , the 3 with 4.5 protection points out of 6.
The worst antivirus in performance
Antivirus has always been one of the most frequent causes for which a computer worked slowly. If an antivirus is poorly optimized, it consumes a lot of memory, a lot of processor and a lot of bandwidth of our hard drives.
It is true that today antivirus programs have improved greatly and practically none will leave our PC unusable due to performance problems. However, there are some antivirus programs that consume more resources than others.
Comodo Internet Security Premium 12 , for example, is the antivirus that gets the worst performance. This only gets 4 points out of 6, slowing down the computer especially when visiting popular websites and installing common programs.
Another antivirus that will also cause performance problems is Malwarebytes Premium 3.7.1 . With a rating of 5 out of 6 in performance, in addition to 2 out of 6 in security, Malwarebytes’ solution is the worst antivirus we can install on Windows 10.
