A well-designed antivirus program helps prevent malware infections and eliminates current threats or attacks against specific computer systems, networks, or entire IT systems. The programs scan files, websites, installed software and user information for malware types that are known to exist. They also monitor the program’s behaviour to identify potential threats.

The majority of antivirus protections provide a variety of scanning methods including scheduled, fast and on-access scans. On-access scans look through directories in the operating system as well as common file areas to search for malicious code on startup. Scheduled scans let you create a daily, monthly or weekly schedule to run a complete system scan at a specific time. Quick scans are typically a few minutes long and examine the most frequently used areas of your computer, including temporary files as well as the operating system directory or memory.

Some programs use heuristics to detect malware, searching for similar tendencies and patterns. This is a more sophisticated method of virus detection than signature-based detection and can detect malware that other programs miss. 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 targeting businesses more frequently as the world of business is becoming more interconnected. They do 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 anti-virus protection to guard them from cyberattacks.
