Several lines of defense are usually combined within the best antivirus firewall software products. Traditional signature based protection consists of searching for known threats. This is achieved scanning files for malicious pieces of code that are known to cause problems to the computer. This is quite effective for detecting viruses and malware that is known to the antivirus vendors however, it is possible for a computer to become infected with threats that are yet to be discovered, commonly called ‘zero-day threats’.
