Free antivirus software offers essential protection against malware without the need for a financial commitment. These programs typically include features such as real-time scanning, malware removal, and periodic updates to detect and remove the latest threats. While free antivirus may lack some advanced features found in paid versions, they still provide a solid defense against common viruses, trojans, and other malicious software. Popular options include Avast Free Antivirus, AVG Antivirus Free, and Bitdefender Antivirus Free Edition. However, users should exercise caution and ensure they download from reputable sources to avoid inadvertently installing malware disguised as antivirus software.
