Cybersecurity is important in today’s digital world. Viruses, malware, and ransomware can harm your devices, steal personal information, and even disrupt your life. The first line of defense is antivirus software. Fortunately, you don’t have to spend money to stay protected. Many free antivirus programs provide excellent security without a hefty price tag.
This article edited by our software experts explains the best free antivirus software that exists as of today. Every one of these has something unique to offer so you can choose the best for you.
Before introducing our list of top free antivirus, let us understand why installing an antivirus is important.
Why Do You Need To Install AntiVirus Software?
Firstly, you can protect your computer from virus attacks. There are multiple types of viruses you can find. However, each can have its unique impact on different devices. Most viruses are transmitted via infected emails or when a user enters a corrupt website.
Secondly, a Spyware attack is something that we all face at one time or the other while being online. Generally, spyware steals your online identity and personal information especially when you do any type of online transaction.
Thirdly, Anti-virus protection can also reduce the amount of spam mail you receive. Receiving mail and ads that you are not interested in can be extremely annoying.

Fourthly, a computer left open for viruses and hackers will often start to show premature signs of wear. In addition to that, you will notice a significant slowdown. And making normal computing tasks take much longer and cause much more hassle.
Finally, if you run the PC without any sort of antivirus program and you get affected, then you need to spend a lot of time detecting and restoring your machine. Hence, it is always advisable to run the computer with effective antivirus software.
