Protection against viruses is just one element of a business’s security arsenal. Cyber criminals are increasingly using sophisticated techniques to bypass antivirus programs and infiltrate computers. Businesses must employ a combination of antivirus, firewalls on networks, as well as other security solutions like malware detection and analysis, threat intelligence and encryption of data.
Review the various providers and make a list of your requirements to find the best antivirus software for you. Search for providers with large customer bases and multiple payment options. It is also important to choose one that provides real-time scanning and regularly updates its malware database. New viruses are continually being developed and the most effective antivirus software can only detect them if they have up-to-date databases.
Signature-based detection is the most popular method to detect malware. It keeps an inventory of distinct code snippets of code that can identify known threats. Antivirus software scans for these thumbprints while scanning, and if it finds a match, it prompts the user to take note of. This approach is not as effective against malware that is metamorphic or polymorphic and encrypts or modifies itself to evade detection by antivirus software.
Another important feature to look for in an antivirus program is heuristic-based protection which examines how malware functions and search for patterns that suggest malicious intentions. This method can help identify previously undiscovered malware, but it can cause security alert fatigue when not well-adapted to the user’s environment.
