Anti-virus 

Software forced onto the unsuspecting masses to combat Viruses. Usually written by ex-virus writters who needed a steady income.

Differs from viruses in intent, and cost. Viruses are usually free, whereas anti-viruses are not. Anti-virus software also tends to have a flashier interface.

Both software types will severely impact your ability to do anything productive, both will occasionally greet the users with unwanted popups, add web tool bars, provide inaccurate (but sponsered) search results, and keep your local IT shop in business.

"The new server anti-virus installed succesfully on the first try. Unfortunatly we couldn't access anything anymore, but we were protected, and that was the important part.

Viruses, turned into hash, then added to the "Black-list" libraries of Anti-viruses.
A type of program which can be easily defeated if you change one line of code in your malware.

anti-virus : You can't defeat me....
malware : I know, but he can...

Norton Anti-Virus 

The MOST overpriced, overrated piece of shit antivirus on the market. Norton is probably one of the biggest piece of bloatware (programs that Hog up way more memory than it needs to) on the market. Plus Norton also gives more false positives than any other pay antivirus. If you want a pay-AV you have to go with something like Kaspersky, which most hackers actually swear by, and it does not hog up memory like Norton.

Jim: Do you have Norton Anti-Virus on your computer?
Scott: No, it's bloatware. I personally use Kaspersky as it's much more lightweight than Norton and also has the best record when it comes to false positives.

norton anti-virus 

(n.) brand of anti-virus that while being very good, disables all the script kiddie hacktools I was playing with, and does not have a simple off button.

Trying to turn off norton anti-virus takes up many hours of my time (I would assume from previous attempts).

Antivirus 

An ISP answer to the virus they sent you last week.

The only 100% effective Antivirus is the 'OFF' button.
