The AVG Antivirus Free application has the same antivirus engine as Avast Free Antivirus. But with Avast you get a free set of extra features. There are 2 reasons you can better choose another antivirus than AVG. AVG lacks extra features that you will get with Avast. And because it makes your system slower while scanning your system. On average, if you compare it with other antivirus programs. For these reasons, we don’t recommend AVG Antivirus Free.

7. Avira Free Antivirus


Avira Free Antivirus once was one of the best options. But all other antivirus programs have upgraded their performance. Avira is still the same as a few years ago. It has some extra functionalities but they are not functional until you buy the paid version. It still has a lot of options and is customizable. But the impact on your PC’s performance is still high compared to other programs. That is why we have listed Avira as the last option in our list.
