A well-designed antivirus program can keep malware infections at bay and eliminate threats that are currently in place or attacks on individuals’ computers, networks, or entire IT systems. The program scans files, websites, installed software and user information for malware types that are known to exist. They also monitor program behavior to detect possible threats.
The majority of antivirus protections provide multiple scanning options, including on-access, scheduled and quick scans. On-access scans look through directories that are part of the operating system as well as common file areas to search for malicious code upon the start-up. Scheduled scans allow you to create the day’s schedule, a weekly schedule or a monthly one to run a full system scan at an agreed upon time. Scans that are quick usually last just a few moments and examine commonly used areas of your computer, for example temporary files or the operating system directory.
Certain programs employ heuristics to detect malware, searching for similar patterns and tendencies. This is a more sophisticated method of virus detection than signature-based detection and it can catch 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 business world becomes increasingly interconnected hackers are focusing on businesses with more frequency to snag caches of customer information or to make some name for themselves with hacktivism (disrupting professional systems for political or social reasons). The protection of antivirus is crucial for all types of companies to have in place to protect against cyberattacks, and keep your company and its customers protected.
