Antivirus software protects against malware, ransomware and other threats. They also safeguard devices from data breaches, identity theft and online fraud. The most effective antivirus software suites also include safety features like password management, VPN and even parental controls. These suites are compatible with both desktop computers as well as mobile devices.
Most antivirus programs employ the signature-based detection method which is a database of distinct code snippets that represent known malware. While scanning the software, it searches for these malware signatures. It warns users when these signatures are detected. However, hackers are constantly generating new viruses with variants that could evade traditional antivirus signatures. This type of malware is known as polymorphic and is designed to evade signature based detection techniques. Certain antivirus programs use cloud detection techniques to identify and stop new threats.
Another thing to look for in an antivirus program is a feature called behavior-based detection. This is a more sophisticated technique which monitors the user’s actions for patterns that could be suspicious. This is especially efficient when it is combined with signature- or heuristics-based detection. It can be used to detect zero-day attacks, which are threats that haven’t yet been classified yet.
Businesses can also select antivirus products that can be scalable to fit their needs. Some are designed to be operated as a complete security suite, offering additional tools such as firewalls, intrusion-detection systems, and multifactor authentication. Managed services providers can help entrepreneurs who do not have the technical expertise needed to set up and maintain these cybersecurity systems.
