Some malware developers have mastered the art of deception so well, that it’s easy to fall for their trap. Take the case of the “Warning Visiting This Site May Harm Your Computer” popup.
A quick glance at the screenshot here will make you think it’s the legitimate warning from Google and Firefox which they created to detect harmful sites. But really, are they very similar? Only if you don’t look closely. The legitimate warning goes this way: “Reported Attack Site!” … then gives you the option to click a button that goes, “Get me out of here!” or another button that goes, “Why was this site blocked?”
The fake warning, however, starts with this message: “Warning! Visiting This Site May Harm Your Computer!”. Then the two buttons are replaced with “Continue unprotected” and “Get security software”, respectively. The layout, theme, color, icon, and fonts, however, look exactly the same as the original. Beware, because this one is fake.
If you click on the “Get security software” button that follows the “Warning! Visiting This Site May Harm Your Computer!” alert, you’ll be directed to a bogus website that will try to deceive you into revealing your credit card information.
How did this happen? Well, getting this fake warning only means warning – your computer’s security has just been breached.
