A well-designed antivirus program helps prevent malware infections and eliminates existing threats or attacks against specific computers, networks or entire IT systems. The program scans websites, files, installed software as well as user data for known malware types. They also monitor program behavior to identify potential threats.
Most antivirus protections offer multiple scanning methods, including on-access, scheduled and quick scans. On-access scans search directories that are part of the operating system as well as common file locations to look for malicious software at startup. Scheduled scans allow you to create a daily timetable, a weekly schedule or a monthly one to run a full system scan at a specified time. The scans are usually quick and last a few moments and will look at the most frequently utilized areas on your computer, like temporary files or the operating system directory.
Some programs employ heuristic analysis to look for malware by looking for similar trends or patterns. This is a more sophisticated type of virus detection than signature-based detection and it is able to identify malware that other programs do not 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.
Hackers are targeting businesses more frequently as the world of business is becoming more interconnected. They use this technique to gain consumer information, or to gain a name through hacktivism. This is when hackers disrupt professional systems to achieve social or political goals. It is vital for all companies to be in place to prevent these cyberattacks and keep your business and its customers secure.
