Antivirus software is the first line of defense to protect your system from ransomware, malware and other cyber-attacks. Even the most technologically adept users may fall victim to adversity so an antivirus program is a must for those who want to keep their data safe. A top-rated program can stop the phishing scams, inform you when a website is compromised, and filter through suspicious emails. A lot of programs offer additional security options such as password managers, VPN access and automatic cloud backups. They can also scan dark web activity to detect the moment your computer is infected.
