Don't lose hundreds of dollars by falling for a computer scam.
The Better Business Bureau says callers are claiming to be I-T professionals.
They charge victims $400 to $500 to remotely access their computer to fix a failed "Microsoft Windows firewall."
Even worse - the scammers leave a program on computers that gives them remote access to your personal information and account numbers.
The BBB says always be skeptical.
Legit tech companies will NEVER contact you about problems with YOUR system.
