Being much involved in the internet marketing business myself, I know the chances of being infected with some of the malware are rather high. This is especially so for someone who gets complacent because such mishaps have never happened before, thinking such stuff will never happen because I have the latest anti-virus software. Remember, a single moment of carelessness is enough to haunt you for a long time, and very often, just having anti-virus software is not enough to protect you.
