A well-designed antivirus program helps prevent malware infections and eliminates current threats and attacks on individual computers, networks or entire IT systems. The programs scan websites, files, installed software as well as user data for known malware types; they also monitor day-to-day program behavior to identify possible threats and alert users.
Most antivirus solutions offer multiple scanning options such as scheduled, on-access and quick scans. On-access scans search directories of the operating system and common file areas to look for malicious code at the time of starting. Scheduled scans let you create your daily schedule, a week-long schedule or a monthly one to run a complete system scan at a certain time. Quick scans typically last a couple of minutes long and look at the most frequently used areas of your computer, including temporary files and the operating system directory, and memory.
Some programs employ heuristic analysis to identify malware by looking for similar tendencies or patterns. This is a much more advanced form of virus detection compared to signature-based detection and can catch malware 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.
As the business world becomes increasingly interconnected, hackers are targeting businesses with more frequency to collect consumer data or to make their name through hacktivism (disrupting professional systems for political or social reasons). The protection of antivirus is crucial for all enterprises to have in place to guard against these cyberattacks and keep your business and its customers secure.
