Why do people run anti-virus software?

Why is it important for us to know this?

I just like to include the word 'porn' in most of my posts.

Its a sticky situation really.

I guess he's just saying it's ok to be risque in surfing and real-life?

The trick is to keep your old system when you get a new computer and use that old rig for the nasty net surfing.

ROFL   Well with your browsing habits you probably are more in need of a cloned backup HDD to swap out when your system HDD goes south on you.

Internet Security protection has had to advance in the last 5yrs from just covering AV, to a host of things like Trojans, [not the condom], Worms, Malware, Spyware, Etc.

These infections have been fine tuned to get in a users computer, allow it to still run while its stealing your goodies in the process, they don't normally cause your machine to crash so you discover they're there, because then you would be forced to do something about it.

So you just blindly surf the net thinking you've dodged all the bullets because your computer is still up and running all the while everything you do is being monitored, and fed out to other sources, using all the information collected like your CC# when you use it, or surfing habits, private information, like what Lulu told you in her chat room.

Once your computer has been compromised and you have nothing what so ever to stop it from happening, all your computer data is up for grabs, but obviously you don't care about that so surf on dude.  

Running a computer with no Internet Security protection in this day and age is really irresponsible, not only to yourself but anyone you use your computer to communicate with.
