Manually run a virus scan in Windows 8/8.1

It's bugged me since 8 came out that I couldn't "get to" Defender. I knew it was supposed to be there but the task tray icon is gone. Well no more!

Put your mouse in top right corner until the right hand charms pop out.

Click on search.

Type Windows Defender

Choose Windows Defender from the results.

You can change your settings, make sure you have the most updated dats, or run a manual scan, from the interface presented, which resembles the Windows 7 Security Essentials UI.

iPhone Texting Fails

"Error Invalid Number. Please re-send using a valid 10 digit mobile number or valid short code."

This from an iPhone 5 with iOS 8.1. Googling the error shows posts back to 2008 with no clear etiology, workaround, or resolution. 

A combination of the proposed fixes seems to have worked for me to fix it this time. I deleted the contact, deleted the message threads (original and error), and did a double button hot restart. Then I texted the problem number. Then created a new contact with the number. Glad to be past it for now. Not sure what service the other person has but I'm on ATT and it was a text not a message (green).
