It goes without saying that due to increasing online threats like ransomware, phishing, and new kinds of malware, the antivirus companies are improving themselves and offering the best possible protection. However, when it comes to delivering the expected performance without taking any money from the users, few of them deliver. That’s why it’s very important to choose the best free software protection by analyzing all the aspects.

Out of these top-ranked best free antivirus software for 2018, I’d suggest you go with Avast Free Antivirus or Bitdefender Free Antivirus. Avast has many bonus features bundled with its free software and it should attract many users. Bitdefender’s software follows a no-nonsense principle and detects threats with ease. So, depending on your personal choice, you can select any of these. You can also install free trials of paid versions of Bitdefender and Avast to see if they are built to fulfill your needs.
