A good antivirus program prevents malware infections and eliminates current threats and attacks on individual computers, networks or entire IT systems. The programs scan websites, files, installed software and user information to look for malware types that are known to exist They also track day-to-day software behavior to detect possible threats and notify the user.

Most antivirus protections offer various scanning options including scheduled, quick and on-access scans. On-access scans seek out malicious code within the operating system directories, common file areas and other common locations upon startup. Scheduled scans let you create the day’s schedule, a weekly schedule or a monthly schedule to run a complete system scan at a specified time. Fast scans are usually a couple of minutes long and look at the most frequently used areas on your computer like temporary files as well as the operating system directory, and memory.

Some programs employ heuristic analysis to identify malware by looking for similar tendencies or patterns. This is a more sophisticated form of virus detection compared to signature-based detection and can detect malware that other programs do not. 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.

As the world of business becomes increasingly interconnected hackers are focusing on businesses with more frequency to score caches of consumer information or to make a name for themselves through hacktivism (disrupting professional systems for political or social reasons). Every business should have antivirus security in place to safeguard them from cyberattacks.
