If there are any words that nobody ever wants to hear, they‘re that “you have a virus on your computer”. Just thinking about the word virus sends chills down someone’s spine. While there are genuinely benign viruses that annoy you (the ambulance virus comes to mind), other viruses, such as Trojans that allow others to access your computer, are not so friendly.
So obviously, antivirus programs are a big market that is expected to reach over 9 billion dollars by 2009. However, not all them are the same, and not all of them pack quite the same punch against the nasty little buggers floating around the Internet.
