Brian from Los Angeles, CA

Brian's doctor is sending him emails that are encrypted. He's supposed to click on a link and then log into GoDaddy to see it, but it doesn't really work. Leo says the doctor is sending the additional security to maintain HIPPA compliance and he's using a third party encryption to do it. Since it's not really accessible to Brian because he's blind, Leo says he should advise them that it isn't working. Leo advises GPG, public key crypto. It uses one key to encrypt, and another to decrypt. Once it's set up, it's outstanding and safe.

Episode 1358

Mark from Grand Rapids, MI

Mark finally got a Google Pixel XL, which was on back order. Leo says it's been widely known that they're only available in limited quantities right now. It's likely that the demand exceeded Google's expectation. Mark says he likes the Wi-Fi assistant because it'll automatically connect via VPN. Does it really work? Leo says yes.

Leo says he doesn't really like joining Wi-Fi access points automatically, so he's turned it off.

Brian is concerned that the more data he creates with his phone and computer, the more data is out there for people to know about him. How can he be more private online?

Why can't I open attachments in Windows 10?

Episode 1321

David from Apple Valley, CA

David upgraded to Windows 10 and now he can't open any spreadsheet attachment without entering a key. Leo says it sounds like Outlook is blocking the opening of attachments to protect him. This is because of ransomware, which has been triggered by opening an attachment. Ransomware, once opened, encrypts all user data and then asks for money to unlock it. So it's a security feature that it doesn't let him open those attachments. He may be able to disable that in settings, but the IT Department where he works probably has that enabled for a reason.

Rich should send a link to the file that's located on a drive like Google Drive, ShareFile, or DropBox.
