Learn dozens of other Facebook settings you need to change right now to protect your privacy.

Avoid a scary IRS scam

Q. I got a call from an IRS agent who threatened to have me arrested if I didn't send them money they said I owed. I'm fairly sure it's a scam, but I'm really freaked out.

A. Don't worry; that was a scam. Scammers like to threaten to have you arrested to scare you.

Is private browsing really private?

Q. I frequently use my browser's private browsing mode. But I'm starting to worry if it's really private. Is it?

A. Private browsing mode just means that your browser won't store history or cookies from the sites you visit. Your Internet service provider and the sites you visit still know you visited. Plus, if you download anything to your computer, it sticks around for people to find. Learn more reasons private browsing isn't totally private and how you can get more privacy if you need it.

Tech skills to put on your résumé

Q. I had someone say that "Proficient in Microsoft Office" doesn't mean much on a résumé anymore. What should I have?

A. If you want tech skills that will catch a hiring manager's eye, "content management systems" are a good start. That just means you know how to use software like WordPress, Joomla or Drupal. Knowing how to do basic Web development coding is another good one, and there are plenty of online resources. Find out what other tech skills hiring managers like to see on a résumé.

Stop Windows 10 lock-screen ads

Q. I got an ad for a game called Tomb Raider on my Windows 10 lock screen. How can I stop those?

A. Microsoft is experimenting with ads in Windows 10, but they're easy to shut off. Windows 10's lock screen images are pulled by default from an online service called Windows Spotlight.
