Jim wonders if he has a virus. He's tried to erase old PDF files and folders and got an error that Windows couldn't. Leo says that some viruses can survive a format, but they're unusual, and are not available in folders easily available on windows. They're usually hiding on the master boot record on in the memory of your video card. It's probably just a precautionary message. You can repartition your hard drive and get rid of them. Would it be safe to move those PDF files to another drive? Leo says so long as you keep your Reader files patched, you'll be fine.
Bob's friend has a computer who's Windows 7 update is taking forever to install. Leo says that Microsoft has patched it seven times to try and and speed it up and in 2016 they finally fixed the issue. Chances are, an update failed and that's what caused the logjam. It also could be malware that disabled the update utility without his knowledge. Leo recommends clearing all the updates and starting over.
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.
Dave has been Christmas shopping online and he found a great deal on a laptop with 16GB of RAM and dual drives with an SSD and a spinning drive. Leo says it's similar to the Mac Fusion drive, where it has the performance of an SSD and the storage space of a spinning drive. Dave is worried that Lenovo has put malware on it, though. Leo says that it was the Superfish adware, and Lenovo got caught doing that -- twice. They have since learned their lesson. Leo likes the Ideapad and at $749, it's a great deal.
Rick has a free file viewer, and it's asking to update the HTML. Leo says don't trust that. HTML is the language of the web and the browser reads it. He doesn't need a special "update" to view it. The first thing Rick needs to do is run Microsoft's Malicious Software Removal Tool. He can do this by pressing Windows Key + R, then typing "MRT" and hitting enter. He should do the full scan.
Jim's dad gets bit by malware often and has to wipe his hard drive several times a year. How can he stay protected? Leo says a great option is to get him a Chromebook. They're more secure, simpler to use, and if all he's doing is surfing and email then a Chromebook is ideal.
Wallace took his computer into a repair shop, and now he's concerned that they could have put monitoring software on his computer. This is a legitimate concern, and often times it happens remotely with people calling that claim to be from Microsoft or something. If someone has physical access to the system, though, all bets are off. Taking a computer into a repair shop is an absolute act of trust. There's not much he could do about it, though, if he needed to bring it in. There's no certification process or national organization of computer techs, so he'd just have to trust them.
Dave upgraded to a Windows 10 Acer PC and his graphics are too large. Then it crashes, causing him to have to reboot. Leo says that's a common video driver issue. Leo says Dave needs to make sure he has the latest drivers from Acer. What Dave needs to do is figure out which video card he has, whether it's a dedicated video card or an integrated video card. He should look in the Device Manager to see the list of hardware. Then once he has that information, he should go to the Acer website and download the drivers. It could be via video card or machine model number.
