FORT MYERS, Fla.- Jim Ostrander of Fort Myers was sitting at his computer browsing the Internet when a window popped up and locked the computer.

It claimed to be the FBI and demanded money to unlock the computer. It said the FBI caught Osterander on illegal websites.

The Lee County Sheriff's Office is saying this computer scam is rising in our area.

"Our calls have been increasing over this particular scam over the last couple of weeks," said Lee County Sheriff's Office spokeswoman Beth Schell.

It then says to pay $200 or the FBI will come arrest him.

The weird part about this particular scam is that it is using your web cam to take your picture.

"It showed my picture and said they have my IP address, the host name and location," said Osterander.

Computer techs say to be safe an add a good anti-virus software and also any good, free malware detection software.
