Antivirus is a type of software program that’s designed to detect, prevent, and remove malware (or malicious programs that steal sensitive data, disrupt computer operations, or gain unauthorized access) from computers, devices, and networks. It is the most important line of defense against cyber attacks for businesses of all sizes.

While the first viruses like Elk Cloner were mostly harmless pranks that spread through floppy disks, they soon evolved into harmful attacks with serious consequences for PC users. Viruses can destroy files, slow down system resources, and log keystrokes to steal sensitive information. And while antivirus programs cannot fully protect against every type of threat, a robust solution combined with safe online practices can significantly reduce the risk of infection.

Most antivirus programs use a method called signature detection, which basically gives each file the equivalent of a digital thumbprint. When it scans a file, the antivirus compares that thumbprint to its database of known malware signatures and flags any matches. This is why it’s essential to regularly update your antivirus software to ensure that it has the latest detection capabilities.

More advanced antivirus solutions also employ heuristic analysis, which examines the behavior of each file to identify suspicious actions and other warning signs. Additionally, some use behavioral monitoring and sandboxing to analyze suspicious files in a secure environment before allowing them on the device. Lastly, many modern solutions use artificial intelligence and machine learning to predict new types of malware and respond quickly to them before they cause damage.
