Grover has a popup that says to call Microsoft Support. Has he been bit by ransomware? Leo says no. Probably not. It's a phishing attack yes, but it's to try and get you to call in and then they charge you and access your computer. it's Scareware really. You an ignore it. But it keeps popping up and he has to reboot to get rid of it. He replaced the hard drive. Didn't help. Still pops up. How can he fix it? Leo says that it sounds like a browser hijack, and when Grover backed up his data, he backed up the malware as well. Make sure to run as a limited, standard user.
The latest ransomware attack is called WannaCry and it's spreading via phishing email attacks. The ransomware not only decrypts your data, but it also has a built in kill switch on websites. Security researchers may have crafted a fix to it, but there's a catch. The encryption is done using Microsoft's bit locker, and the fix is to take advantage of a flaw in the cryptographic memory that keeps the keys in RAM, so it can harvest them and unlock your data.
Melinda says that after she turns on her computer and goes into her browser, it takes a really long time to get to Gmail, and it goes to her eBay and other accounts. She wonders if she got hacked. Leo says perhaps. That kind of behavior points to being hacked. Maybe someone has gotten physical access to the computer. Did she make an enemy?
Jim bought a pair of Samsung Galaxy S8 and the guy at the store said he doesn't need an antivirus app to protect it. Is that true? Leo says it is. Mobile phones don't really need that extra precaution, as long as he only gets his apps from Google Play Store. He should be careful what apps he gets, though, even then. Sometimes a junky app does get through. The benefit through Google Play is that if one gets through, they will remotely kill it.
Janet has a 2014 MacBook Air and she's got malware. Leo says it's very rare to get malware on the mac, so it's unlikely. Janet is getting redirected to other sites. That's a browser hijack, not a virus. It's malware, but it's browser level malware. The laptop has also died as a result. Leo says that hardware can die, especially a laptop that's being carried around. A MacBook Air may be more prone because it's so thin. It could also just be a bad logic board or diode on it. It's not related to the malware/browser hijack issue, though. It doesn't work that way.
Doug's in laws are getting popups in Chrome using Facebook that malware is on their machine asking them to download something. Leo says that is a fishing scam trying to get them to download and install something. Leo suspects that there is a malicious extension in Chrome that is causing it. Leo suggests resetting Chrome to wipe out everything. They'll have to reinstall the extensions, but it's the only way to be sure. They should go to Settings and search for Reset. That'll make it go away.
We're familiar with DDoS attacks, which are "Distributed Denial of Service" attacks, but there's a new form of attack that's been happening online lately. It's called PDoS, or "Permanent Denial of Service," which actually bricks the device, destroying it permanently. The rationale is that if these devices weren't bricked, someone else would use it for a DDoS attack.
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.
