A well-designed antivirus program protects against malware infections and eliminates existing threats or attacks against specific computer systems, networks, or entire IT systems. The programs scan websites, software, files, as well as user data for malware types that are known to exist; they also monitor day-to-day program behavior to identify potential threats and alert users.

Most antivirus solutions offer multiple scanning methods which include scheduled, on-access and quick scans. On-access scans look through directories that are part of the operating system as well as common file regions to search for malicious software at starting. Scheduled scans let you create a daily, weekly or monthly schedule for running a complete system scan at a specific time. Scans that are quick usually last just about a minute or so and examine commonly used areas of your computer, including temporary files or the directory of your operating system.

Certain programs use heuristic detection to scan for malware by Continued looking for similar trends or patterns. This is a much more advanced form of virus detection compared to signature-based detection and can detect malware that other programs can’t. These advanced forms of antivirus detection may not work as well for small businesses, as they are often prone to false positives–identifying secure parts of files and programs as potentially harmful.

Hackers are increasingly targeting businesses as the world of business becomes more interconnected. They are doing this to obtain information about consumers, or to build a reputation through hacktivism. This is when hackers disrupt professional systems to achieve political or social goals. Every business should have antivirus security in place to safeguard them from cyberattacks.
