A reputable antivirus program can prevent malware infections and eliminate threats that exist or attacks on individuals’ computers, networks or entire IT systems. The programs scan files, websites, installed software, and user data for malware types that are known to exist. They also monitor the program’s behaviour to identify possible threats.
Most antivirus protections offer a variety of scanning methods that include scheduled, speedy 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 at the time of startup. Scheduled scans let you set up a daily weekly or monthly schedule for running a complete system scan at a certain time. Fast scans are usually a few minutes long, and they examine the most frequently used areas on your computer like temporary files and the operating system directory or memory.
Some programs use heuristics in order to detect malware, searching for patterns and tendencies that are similar to those found in other programs. This is a more sophisticated method of virus detection than signature-based detection and it is able to detect 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.
As the world of business is becoming more interconnected hackers are focusing on businesses with more frequency to snag caches of consumer data or to make an image for themselves through hacktivism (disrupting professional systems due to social or political reasons). Antivirus protection is essential for all kinds of companies to be in place to protect against cyberattacks and ensure that your company and its customers safe.
