These free antivirus editions are capable of scanning for malware, and often have the option for automatic scans. Some free editions also have additional protection tools such as a built-in firewall or a browser add-on that checks for bad links.

With a free antivirus edition, you can increase the tool's basic security with countless security utilities and there is indeed a huge number of mix-and-match combinations with other free tools, VPN services, browser add-ons, and programs you can choose from to customize your protection suite to fit all your requirements without spending any money.

What is Antivirus Software?

Antivirus software is a program designed for detecting, removing, and preventing malware infections on separate computing devices, IT systems, and networks. It is also capable of protecting against an extensive range of threats, including various types of malicious software, such as Trojan horses, keyloggers, botnets, spyware, ransomware, worms and browser hijackers.

Antivirus Software: Basic Functions

  • Allows users to schedule scans to run automatically
  • Allows users to initiate new scans at any time
  • Scans directories or particular files for known malicious patterns indicating the existence of malicious software
  • Removes any malicious software it detects. A few antivirus software programs are capable of doing this automatically in the background, while others notify users of infections and ask them if they want to clean the files.

Antivirus software must specifically be given privileged access to the whole system in order to scan systems in a comprehensive manner. This allows antivirus software itself to become a common target for attackers. Recently, researchers have discovered remote code execution and various other serious vulnerabilities in antivirus software products.

  • Offers protection at no cost
  • Option for testing a number of products
  • Uninstall unwanted antivirus without losing financially
  • Good for the pocket as your money remains intact
