This is very common I get calls about it at least once a week. The websites locks your browser and displays a message stating there is some type of problem with your computer,
sometimes it plays an alarm sound or a voice message stating there is some type of problem with your computer. It then displays a toll free number to call, if you call you will get a hold of some one wanting $200-$300 to “fix” your computer. This is a scam and in all likely hood there is nothing wrong with your computers. Check out this video about the scam on NBC News. While in the video it states that the business is being closed I have a feeling this isn’t the only one out there.
How to get this off your computer:
If you use your computer for online banking, bill paying or managing your stocks I strongly advise you purchase a quality anti-virus product.
