Should I copy protect my eBook?

Mark from California

Episode 1407

Mark has written an ebook and he wants to know if he should copy protect it. He's going to be giving it away for students to see if they like it. The LA Sparks want him to copy protect it. Leo says he's not a fan of DRM because it simply doesn't work. The bad guys know how to remove it. But if you have to, it depends on which scheme you use and how do you authenticate it? That's why it's so tedious for those who aren't going to pirate it, but it can be easy for those who will. You'll need to have an authentication server to verify it. See how problematic it can be?

How can I stop getting malware?

Steven from Los Angeles, CA

Episode 1404

Steven got a virus on his computer and it keeps coming back. The tech says they are getting into his computer through his IP address. Leo says that they don't know what they're talking about. He can't get it that way and if they're trying to sell him software to fix it, then he needs to find a new technician to repair his computer.

Leo suggests trying Geek Squad at Best Buy. They're a good place to start. At least it's a technician that's local, that he can visit. But at the end of the day though, his best defense is his online behavior.

Synology DS416 Slim

Petya is the Latest Ransomware Scam

Episode 1400

Petya is the latest ransomware hitting millions of computers around the world. Most infected computers are in the Ukraine, where "patient zero" is believed to be. From there it branched out to Russia, Poland, Italy and Germany. It takes advantage of the same flaws in Windows 10 that WannaCry did. Fortunately, it hasn't really hit the U.S. yet, but we'll see more infections as time goes on. Our CIA intelligence service discovered it and didn't say anything because it could use it to spy on others.

Why is my browser typing strange text?

Episode 1398

Jeff from Apple Valley, CA
Keyboard

Jeff is getting strange random key strokes appearing in his browser bar. Leo says to try a different browser. Windows comes with both Edge and Internet Explorer. If it happens in both browsers, it could be a failing keyboard. Jeff should unplug his keyboard and try a new one. If he still has the issue, then it's a Windows problem, which could be malware or a browser hijack. He could try resetting his browser first. If that solves the problem, then he's fine. If not, then it may be that he'll need to reinstall Windows from a known good source.

Are Java updates safe?

George from California

Episode 1397

George wants to know if he should update his Java? Is it OK to update? Jason says that it's often OK to ignore them, but if it's an important security update, or if it's required for him to use a website, then it's a good idea to stay updated. It's definitely safer security wise to do so. But Jason also recommends getting rid of Java altogether. When in doubt, though, always go directly to Oracle to get updates. That way he'll know it's always official.
