It is important to understand the difference between an antivirus program and internet security software. Antivirus and internet security have the same purpose: securing your online activity and digital life. The difference between the two lies in the features offered. Antivirus has the most basic of features; while the latter has much more to offer and is considered more comprehensive protection. Antivirus, as its name suggests, usually only has protection for virus and other malicious software like Trojans and worms. Internet security software on the other hand, has additional features such as firewall, safe browsing, parental controls, identity theft protection, and more.
