Have you been the victim of scareware? You probably already are infected and don't even know it. The other day I was reminded of how easy you can get deceived online by ordinary system pop-ups. Here is an example of how you can be duped by scareware and what to do to avoid it.
I was searching for the latest hit movie and all of a sudden a box popped up on my screen that resembled something that was from my operating system. I know that I had my pop-up blocker on so I was tempted for a moment to click on it. The box said “You've been infected by a Trojan Virus, click here to run a scan.” I then immediately hit the red x and closed the box. Then I ran my own local virus device which came up clean.
