A well-designed antivirus program can keep malware infections at bay and eliminate existing threats or attacks against the individual computer, network or even entire IT systems. The antivirus programs scan websites, files, installed software and user data to search for known malware types and monitor day-to-day program behavior to identify potential threats and alert the user.
Most antivirus protections offer various scanning options that include scheduled, speedy and on-access scans. On-access scans search for malicious code in the directories of the operating system, the common file areas and other common locations upon startup. Scheduled scans allow you to create a daily, monthly or weekly schedule to run a full system scan at a specified time. Quick scans typically last a few minutes long, and they examine the most frequently used areas on your computer, such as temporary files as well as the operating system directory, and memory.
Some programs use heuristic detection to identify malware by looking for similar tendencies or patterns. This is a more sophisticated kind of virus detection than signature-based detection, and it is able to detect malware that other programs don’t detect. 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 more interconnected hackers are targeting businesses with more frequency to collect consumer data or to create some name for themselves with hacktivism (disrupting professional systems for political or social reasons). It is vital for all kinds of companies to be in place to prevent these cyberattacks and keep your company and its customers safe.
