The protection of viruses is just one part of the arsenal of a business. Increasingly, cyber criminals are employing more sophisticated techniques to bypass antivirus software and enter systems. Businesses must employ an anti-virus system that includes network firewalls, and additional security solutions like malware detection and analysis, threat intelligence and encryption of data.

To find the most effective antivirus program that meets your needs, make an outline of your needs and then compare the various providers. Find providers that have an extensive customer base and multiple payment options. You should also pick one that offers real-time scanning and regularly updates its malware database. The best antivirus software can only detect new viruses if it has current database.

The most common method for detect malware is signature-based detection, which maintains an inventory of code snippets that identify known threats. The antivirus software scans these thumbprints and, in the event that a match is detected, warns the user. This method is less effective against malware that is polymorphic or metamorphic and encrypts or modifies itself to prevent detection by antivirus software.

Another important feature to look for in an antivirus program is heuristic-based identification, which analyzes how malware functions and search for patterns that suggest malicious intentions. This approach can help spot previously undiscovered viruses, however it could lead to security alert fatigue if the program is not correctly adapted to the user’s specific environment.
