Lisa went to a website and she got a pop up notification that her computer was infected and to call an 800 number to Microsoft. Leo says not to ever call them -- just exit the popup and move on. It's not infected and those popups are designed to insnare users. It's called a phishing scam. Lisa did it anyway, though, and gave them control of a computer. Leo says that's bad news because she doesn't really know what the hacker's done. He can install viruses on her or turn it into a bot, a keystroke logger, and use remote access to turn on her camera.
Darryl is getting messages to upgrade Adobe Flash on his Mac. Leo says do not reply to any message to upgrade your Flash, do directly to Adobe and get the update there. Hackers can compromise websites to include a bit of code to get you to click on a link. It's called a Phishing scam. Flash auto updates now. Or you can use Google Chrome and it will auto update as well. So never click on a link that offers to install an update to flash for you. It's a scam. Another thing you can do is redownload your browser, delete them and reinstall. That will renew certificates.
Jennifer's computer has been displaying a message that her computer has been blocked unless she calls a number. Leo says it's probably a popup from the browser. There's nothing wrong with her computer -- it's a scam. She should just clear her browser cache, then reboot the computer and it should be fine.
Ann got an email notification from Yahoo in her inbox. She had a hunch it was bogus but didn't do anything with it. Can she still get hacked if she opens it but doesn't click on any links? Leo says that a bad guy has to get her to run a program. Leo says that opening the email is relatively harmless, so long as she doesn't click on any links.
Mike wants to know how to tell a real email from a phishing email. Leo says to hover over any link that would send him to a website, and see if the link is legitimate. He should never click on it. If it says to install something, or even asks for a credit card, don't do it. That's usually the first sign of an intent to do something nefarious.
Cheryl wants to know if she can get infected by HTML email. Leo says yes. That's why she has to be careful what links she clicks on. But since she's using an iPad, she's protected. She can't get infected on that. Apple's iOS is very secure. But it's always a good idea to train herself not to click on links. If she gets an email from her bank for instance, she should just go to her browser and go directly to the bank's website.
Clay keeps getting email from Google saying someone tried to access his account with a link to say "check your devices." Leo says it may be legit, but he should never click on links in email. Instead, if he's a Gmail user, he can go the bottom of his Gmail and find a link that gives him information on who has used his account. He shouldn't ever click on a link or button embedded in his email. It could be a spoof or phishing scam. Always go straight to the source.
Frank got fooled by a Phishing popup. He called the 800 number that was associated with it and they charged him $300 to "fix it." Leo says they were pretending to be Apple Care. It's a scam. Frank suspected chicanery and called Apple Care, who confirmed it was a scam. Leo says that's a smart thing. So he turned off the computer. He doesn't see anything wrong with his computer, but what should he do? Leo says that chances are they probably didn't get far, so Frank is probably OK.
Glen got a popup saying his computer has become encrypted, and he keeps getting popups saying it's been infected with adware. Leo says it's bogus and isn't the CryptoLocker encyption scam. It's just a scam trying to get him to call to give them his credit card and remote access control to his PC.
Mark has an iPhone 6 Plus, and he clicked on a link in his email from "Fedex" which he later realized was a bogus phishing scam. Leo says it's unlikely it'll impact Mark. Phishing scams are designed mostly at Windows applications and even then, unpatched versions of Windows. Since Mark is neither, it's highly unlikely anything bad will happen to his phone. But it's good that he realized it, even if it was too late. Next time he'll know beforehand.
