To do this, we reveal the host of the Today Show who just fell for itYou are surfing the Internet and an important security message pops up out of nowhere, this scary warning that your system was infected, it was hijacked and your personal and financial information is not risky and the only way to fix it is by calling the number on the screen, it looks real like it came from your own computer but it's actually a fake, it's really a pop-up ad I just opened the door and just let someone into my computer it happened to Natalie when she was online, she panicked and called the number they told me they are a reputable company that works with Apple and Microsoft, so they did it right away asked for access to my computer through LogMe I don't know, I shouldn't have done it, you did it, you didn't care, yes I did Jeff, me know once inside they cheated on her hard drive and told her it had a virus but good news for $ 400 they will fix it, it was kind of like the lightbulb went off because at that point i knew what they offered, wasn't it true security experts say these pop-up ads are misleading and dangerous, it looks like a warning but it's not real, it's just a picture I'm calling you, something is wrong with your computer but there's something really wrong with your computer, we're going to try ourselves, we're going to call one of the companies that are sending out those pop-up alerts, went to the store, bought a brand new MacBook Air laptop, and you can see it's straight out of the box, we brought our computer expert in Jim Stickley here when they tell us on the phone that there is a virus, which means they are trying to rip us off or still shut down hey they are trying to fix their own malware i get my phone, we call them i saw a pop-up supposed to call this number because of a computer virus. Can you help me, the tech immediately asked to tap into my computer and once inside we watch him rummage through my laptop in real time and within seconds he has bad news so why not maybe someone try other access to república that's right he says not only is there a virus on my computer someone is trying to hack it k in I'll give up this machine and do the pickup then you come here, hey you bought the thunder but remember That this computer is brand new then comes the sales pitch What will it cost me to fix it, if people have a one year contract, will it call you a hundred? Ninety nine nine bucks time for the big reveal My name is Jeff Rossen I'm the national investigative correspondent for NBC News and this is a brand new computer that just came out of the box ok ok ok i'm not going to show me the virus, where the virus is i will tell you the letter you tried to sell us a package our computer expert says we didn't need it it is a brand new computer i am not trying to sell a package and provide new tech help just you don't let me show you after a few minutes, he still can't show us any virus and then look at that he starts surfing the web you type yahoo.com into google you can let go of the remote connection, thank you very much for your time Whether you're smart or stupid, or you're old or young, it's just one of those things that, when caught by surprise, falls for an urgent warning to scare you off I learned a good lesson, next my gut says what Jeff Rossen would always give good advice, which these technicians can be persistent by the way, Natalie found out, but no matter how official they sound, we have Apple and Contacted Microsoft, both told NBC News that they are not affiliated with these companies that create the ads.
The best advice, if you get this popup on your screen, hit Escape and Natalie I know you. Come from LA, you should be on the run now I know, well, I tried, but it was just that they froze again and so was the way that my information could be compromised, that you know i was going to get hacked Imean, that was kind of scary for me i know i'm not the only one falling forward like you mentioned, hundreds of others and probably thousands of others including my father-in-law have exactly the same thing and Natalie spent some money on it too, but she had to bring her computer, take your computer to someone else, and spend hundreds of dollars to make sure the virus didn't get on it.Yes, I just took it to my computer expert to make sure it hasn't actually been compromised or hacked Well the good news is Jeff you have a new computer that I'm sure of I sure did and I'm not giving it back either, haha, thank you for being a good sport now Jeff, thank you, good lesson, thank you, thank you
