Does my Mac have ransomware?

MacBook Pro

Episode 1505

Justin from San Diego, CA

Justin's mother-in-law has a MacBook Pro that has ransomware on it. She just gets a blue screen. Leo says that Macs don't get blue screens, they kernel panic. It's likely an exploit in Javascript that is locking up her cursor to make her think the computer is frozen. She can press ALT + TAB to get out of the browser and she'll probably be fine. Then, she should turn off Javascript. Leo says it will not happen after that.

Block Malicious Content in Your Browser

Many websites on the internet use Javascript. In fact, it's often critical for websites to function at all — it's not optional. That being said, Javascript can be used maliciously to compromise your system, or simply use your computer to do things without your knowledge. For example, there are a lot of websites these days, such as CoinHive, that are making money by running a little bit of code on your computer with the purpose of generating cryptocurrency.

Block JavaScript and Pop-Ups in Your Browser

Chances are good that at some point while browsing the web, you've encountered annoying pop-ups with suspicious warnings or messages. There are even some scams that pop up a message saying you've been involved in illegal activity and prompt you to pay some amount of money to "unlock" your system. Most of these scams are done through JavaScript, and disabling this would prevent this from happening.

Do I have malware on my system?

Episode 1213

Dave from Portola Hills, CA

Dave was on a government website and he got a popup that he may be infected with malware, which forced him to reboot the system to get out of it. He's worried now that he's been infected. Leo says that's a good instinct. This has been happening a lot. Often, it happens if you've mistyped the URL, which leads you to a malware site. This is most likely from Javascript, though, which doesn't impact your computer and is designed to scare you into installing something or paying someone to claim to unlock it.

How can I stop popups from crashing my phone browser?

Episode 1213

Ed from San Jose, CA

Ed was surfing on his iPhone in privacy mode and his app screen suddenly locked when he was searching, saying he was engaging in illegal traffic and he had to pay $500 to unlock the screen. Leo says that's a scam done by Javascript. His phone really isn't locked down. It's not leaving anything on the system. It's "sandboxed." It's not perfect, though, as there could be holes in the Javascript code. Leo suggests double tapping the home button and swiping up to kill the app. On the desktop, NoScript will prevent this from happening by blocking Javascript.
