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.
Eric has been a long time AOL customer. AOL recommended SlimCleaner Plus and he trusted it. Leo says it was an ad that AOL sold and Eric got bit. He tried to remove it and now he's getting popups saying someone is trying to access the account. Leo says that's trying to prevent you to uninstall it and that's bad behavior. Look for an uninstaller. At worse, you can backup your data and reinstall Windows. But ignore the popup and uninstall it anyway. And don't trust ads. Just because they come from AOL doesn't mean it's a good thing to get.
Diane got a popup that said she had a virus. She knew it was a scam and closed out her Safari browser and turned off her computer. Then she got a bank notice that her account was compromised. Are those occurrences related? Leo says probably not. Just because a popup tells her she's infected, it doesn't mean she is. The popup was designed to get her to call someone so they can socially engineer her to install something. The bank notice probably was the result of someone who she gave her card to at a restaurant copying her information. Her Mac is safe.
Susie was at Burger King, using their Wi-Fi and she started to get pop up ads. Leo says that Burger King is offering free Wi-Fi and they're paying for it by intercepting customer traffic and inserting ads. And that's troubling. Lenovo did something similar on their consumer computers with Superfish. The good news is, they aren't modifying the computer, they're just modifying the traffic. The good news is, there's probably a McDonalds or a Starbucks just down the street that aren't doing this. Choice solves problems like this.
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.
Frank gets a popup Windows update request and he doesn't know if he can trust it. Leo says that Frank is right to ask that question. He'll want to be careful, say "no," and then go to Windows Update and search for them there. It's always a good idea to reject anything that's pushed onto him online.
Martin got a popup that says that Microsoft suspects malicious activity that's causing "system breakage." Leo says it's a scam. A popup doesn't mean he's infected, but if the grammar is bad, then it's likely a scam. Since Martin is using Internet Explorer, Leo advises updating to IE11 and run his updates. Leo also suggests using Google Chrome instead. It's far safer. He'll never see those popups again with Chrome.
If Martin is using Windows 8, then he's got Windows Defender built in. If not, then he should download Microsoft Security Essentials.
Joe keeps getting an annoying popup, and he has no idea where it's coming from. Leo says that popups usually come from installing a tool bar. Often, installing shareware will come with an additional "payload" because users didn't uncheck and disable it from installing. Leo calls it "sneakyware", because it slips by the user when they're installing something.
