Is Windows Defender the best AntiVirus?

Windows Defender

Episode 1708

Jim from Calabassas, CA

Jim wants to know if Windows Defender is sufficient to protect his Windows machine against malware. Leo says yes and now. You are your own last line of defense and your online behavior can undo the hard work Defender does to protect you. Don't click on links in an email. Only get your software from original vendors. Keep DEFENDER and Windows 10 up to date.

Defender is as good as any other antivirus, but safer since it's designed specifically for Windows.

Why are Yubikeys So Secure as an Authenticator?

Yubikey

Episode 1689

Kevin from Vancouver, BC

Kevin wants to know if the Yubikey is better than other hardware authenticators. Leo says probably not. Hardware is pretty ubiquitous now. And the mere presence of the hardware is key because it's a physical authenticator that generates a one time code that is tied to the physical key. So it's very secure. The worst is an SMS text authenticator.

When should I replace my mobile phone?

Samsung Galaxy S5

Episode 1686

Richard from Grand Rapids MI

Richard has a Samsung Galaxy 5 and wants to know when he should replace it. He's gone through two batteries. Leo says that a smartphone will become good as new when you put a new battery in it. So that really isn't an issue. The real issue is when the updates stop. When the phone OS is no longer supported because of age, that may be the time to get a new phone. But if you're not installing anything new, you're probably fine for as long as you want. 

Google Bans Zoom on Employee Computers

Google

Episode 1685

Due to security issues, Google has banned the video conferencing software ZOOM from all employee computers.  While Zoom is much easier to set up and use for most people, it does install a web server on your computer, that ends up being left active after you uninstall it. Leo says that Zoom has hired some new security experts in order to shore up their security, and Leo says that's the right move. Until then, Leo recommends JITSI. It uses the browser's WEBRTC feature, so there's nothing to install
