Virus protection is only one aspect of an organization’s arsenal. Increasingly, cyber criminals are using more sophisticated techniques to evade antivirus software and enter systems. To keep up, businesses must rely on a combination of antivirus, network firewalls as well as other cybersecurity tools, like malware detection, behavioral analysis, threat intelligence and encryption of data.
To find the ideal antivirus software for your needs, start with an outline of your needs and then compare the various providers. Choose a provider that has an extensive user base and offer multiple payment options. Choose a company that provides real-time scanning and regularly updates their malware database. The best antivirus software can only detect new viruses if it is equipped with an updated database.
The most popular method of detaching malware is to use signature-based detection. It maintains an inventory of code snippets that identify known threats. Antivirus software scans for these thumbprints when it scans and, if it finds a match, it sends the user to take note of. This approach isn’t as effective against metamorphic or polymorphic malware, which encode or modify themselves in order to evade detection by virus-scanning software.
Heuristic-based detection is a crucial feature of an antivirus program. It examines malware and searches for patterns that indicate malicious intentions. This method can help identify previously unknown viruses, but if it’s not adjusted to the user’s environment, it can lead security alert fatigue.
