Test your router

Q. I heard you say on your national radio show that hackers are attacking routers. How can I make sure my router is secure?

A. You heard me talking about DNS hijacking. Using commonly available tech tricks, hackers can redirect your Internet travels. You open your browser and type in a web address, and you think you’re at a legitimate site. But, in fact, you’re directed to a really good-looking fake site that’s loaded with malware, viruses or worse. You can test your router for any DNS hijack vulnerabilities. Click here to take this simple test from security company F-Secure. If you find a problem, do a factory reset of your router and then follow these step-by-step instructions to make it more secure in the future. Don't forget … you can tweak your DNS settings yourself to speed up your Internet and make it safer.

Find hidden social media accounts

Q. I think my son has online accounts I don't know about. How can I find them?

A. I would start by searching his browsing history and the apps on his phone. But if he's good at hiding things there, you can find his accounts with an online search. Run a Google search on his name, email address and the username he uses for the accounts you know about. It's likely he's used one or more of those for every account. The username will be in the Web address of the account. For example, my Facebook is https://www.facebook.com/kimkomando, which means my username is "kimkomando."

Set your insurance record straight

Q. I'm trying to get car insurance after not driving for a while and my quotes are astronomically high. One company told me it's because of an accident I had last year, but I didn't have one. What's going on?

A. Insurance companies base your risk level on a report called the Comprehensive Loss Underwriting Exchange. The C.L.U.E. is a record of your past insurance, losses, injuries and claims for both auto and personal property. If there's a mistake in that report, it can affect your auto, homeowner or renter's insurance premiums. Fortunately, you can get your report online for free and submit corrections.

Get better action shots

Q. I use my iPhone's camera for everything, and it usually works OK. But I'm not getting good action shots at my son's soccer games. I don't want to buy a regular camera. Help me Kim!

A. If you're filming people in motion, use Burst mode. Tap and hold the shutter button (or volume up button) and the phone will take rapid-fire shots so you get every second of action. When you want to stop shooting, release the button and the photos will appear in your Camera Roll. Also, consider getting a small tripod for steadier shots.

Better reading on a smartphone

Q. I would love to get a smartphone, but the text on the Android my husband has is so small. Is there a smartphone for those of us without eagle eyes?

A. Android has a number of built-in readability tools that can help. For example, go to Settings>>System>>Accessibility and turn on "Touch zoom." Now you can tap the screen three times in a row to zoom in on something that's too small. Tap three times to zoom back out. If you want to make all the text larger, go to Settings>>Accessibility>>Font size and bump it up to Large, Very Large or Maximum.

Bonus: What Windows 10 upgrade will you get?

Q. I'm currently running Windows 7 Ultimate. When I take the free upgrade to Windows 10, will I still have Ultimate, or will I have to use Home?

A. Microsoft is upgrading whatever version of Windows 7 you have to the closest equivalent. If you have Windows 7 Pro or Ultimate, you'll get Windows 10 Pro. If you're running Windows 7 Starter, Home Basic or Home Premium, you'll get 10 Home. Windows 8.1 had only Home and Pro to begin with, so those are direct upgrades.
