Antivirus Internet Security Software is used to defend against internet threats such as viruses, Trojans, spyware and more recently phishing scams. Antivirus software detects and removes these types of threats which are commonly grouped together using the term ‘malware’.

Several technologies are usually combined within the better antivirus firewall software products. Traditional signature based protection consists of searching for known threats. This is achieved through scanning files for malicious pieces of code that are known to cause problems to the computer. This is quite effective for 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’.

To protect against zero-day threats, proactive heuristic scanning such as ESET NOD32’s ThreatSense technology can be used. Intrusion prevention technologies are fast becoming the norm within the next generation of antivirus internet security software with the aim of defending against unknown threats.

It’s often said that if you are connected to the internet using a Microsoft Windows based operating system without antivirus security software installed, you are probably going to be infected with malware in less than 60 minutes. When you think about it like this, buying a premium brand of antivirus internet security software product should become one of your top priorities.

With such a large choice of antivirus security products available on the market today, how do you choose antivirus software that best meets your needs? Simple, you start by asking yourself a set of questions:

  • Do you only require antivirus protection or do you need additional protection such as antispam, anti spyware and application control?
