Small businesses are increasingly targeted by cybercriminals due to their often limited IT resources and less mature security infrastructure. Malware, ransomware, spyware, and phishing attacks can lead to data breaches, financial loss, and reputational damage. Choosing the best antivirus software for small businesses is critical to ensure comprehensive protection without disrupting daily operations.
