Norma Charles recently got an alarming phone call from a man she said had a heavy accent.

"I'm always a little bit wary. You hear about this all the time, and I said 'I’m not sure I trust you or not,'" Charles said.

From the start she said she knew something was wrong. The man on the other end told her he was from Microsoft, and said that her computer might crash any minute.

"He said ‘oh I’ll show you how bad it is,’" Charles said.

The scammer directed her to a website (teamviewer.com) and from there, Charles said he just took over, controlling her mouse from his end of the phone.

He told her he could fix the problem, but it would cost her more than $300. It was at that point Charles had enough and hung up.

"I knew it, I knew it (was a scam) right away. I just kept telling him I didn't trust him (he said) ‘oh but you can I’m Microsoft,’" Charles recalled.

Because of Charles’ limited mobility, she relies heavily on her computer to shop and get necessities. Although she didn't completely fall for this scam, she just wants everyone to be careful when getting calls like these.
