The protection of viruses is just one part of a company’s arsenal. Cybercriminals are increasingly employing sophisticated methods to get around antivirus software and penetrate computers. To stay ahead, businesses have to rely on an array of network firewalls, antivirus as well as other cybersecurity tools, including malware detection, behavioral analysis, threat intelligence, and encryption of data.

To find the most effective antivirus solution for your needs, start with the list of your requirements and compare providers. Find providers that have a large customer base and multiple payment options. You should also select a provider that offers real-time scanning and regularly updates its malware database. New viruses are constantly being created and the best antivirus software can only detect them if they have updated databases.

The most widely used method for detect malware is signature-based detection. It maintains a database of distinct code snippets that detect known threats. Antivirus software checks for these thumbprints when it scans and, if it detects the same pattern, it will issue users to be warned. This technique is not as effective against metamorphic or polymorphic malware, which can encrypt or otherwise modify themselves to deflect detection by virus scanning software.

Another important aspect to look for in an antivirus program is heuristic based detection that analyzes how malware functions and searches for patterns that suggest malicious intent. This approach can help spot previously undiscovered viruses, however it can cause security alert fatigue if not appropriately tuned to the environment of the user.
