RICHMOND, VA (WWBT)- The aftermath of disasters like the tornado in Moore, OK can bring out the best in people -stories of heroism, of help, of survival... but it can also bring out people who want to take advantage of your generosity. Urgent appeals for donations by phone, email or social media are probably not on the up and up and are likely scammers.

According to the National Weather Service, Moore residents had 36 minutes to get ready for death and destruction in Oklahoma.

The first code red warning sounded at 2:40 p.m. Monday, 16 minutes before the tornado touched down 10 miles west of the city. It reached Moore at 3:16.

"We hope this inspires people in Richmond to take steps to prepare now, whether that's downloading our Red Cross tornado app or just having a conversation with our family about what would they do if a storm did come through Richmond," said Jonathan McNamara with the American Red Cross.

RICHMOND, VA (WWBT)- Several organizations will allow you to send $10 directly to the Oklahoma disaster zone by sending a text message. The donations will simply be added to your cell phone bill, no credit card information is required. You need to be 18 or older, or have parental permission, to donate this way.

RICHMOND, VA (WWBT)- Crooks are hijacking computers with a scheme called Ransomware. If they gain access, they can lock your computer and make it appear you are in legal trouble and you need to pay a fine.

If you are victim of Ransomware, cyber criminals lock your machine and claim the only resolution is to pay up. Crooks usually disguise the message as if it's coming from a law enforcement agency, like the FBI. Cyber Expert, DJ Rivera, says it's happening more and more and people are falling for it. "You can get from a USB Stick, browsing some internet sites, from downloading files, photos, clicking links, there are basically just an infinite number of ways," Rivera says.
