Antivirus products offer protection from malware such as ransomware, phishing attacks, ransomware as well as spam attacks, spyware and more. They also safeguard devices from data breaches, identity theft and online fraud. The best antivirus software suites come with additional safety features like password managers, VPN and even parental controls. These suites are compatible with both desktop computers as well as mobile devices.
The majority of antivirus software employs signature-based detection. This method keeps the database of code snippets which represent known malware. When it scans the antivirus software is looking for these signatures. It warns users when these signatures are detected. Hackers are constantly developing new viruses that can defy traditional antivirus signatures. This kind of malware is known as polymorphic and is designed to bypass signature-based detection techniques. To combat this, some antivirus programs employ cloud-based detection tools that make use of global intelligence to identify and stop new threats.
Another feature to look out for in an antivirus software is behavior-based detection, which is a more sophisticated method which monitors the user’s actions for patterns that could be suspicious. This is particularly efficient when it is used in conjunction with signature- or heuristics-based detection. It can also be used to detect zero-day attacks, which are threats that aren’t being catalogued yet.
Businesses can also pick antivirus solutions that are scalable to fit their needs. Some are designed to be operated as a full security suite that includes tools like firewalls, intrusion-detection systems, and multifactor authentication. Many business owners do not have the technical know-how to set up and manage these cybersecurity systems, and can turn to managed services providers for help.
