What is Teredo and why is it affecting my Internet access?

Episode 1056 (1:02:05)

Myrna from Lake Tahoe, NV

Myrna has lost her internet connection. She also found something called "Teredo" on her machine. Has she been hacked? Leo says no. Teredo is a new software standard which gives access to IP vs. 6 Internet IP addresses, called "IP tunneling," and Myrna's ISP probably enabled it as it was already part of Windows. She can read more about Teredo here.

It may have also been part of Verizon's Security Suite, which is her ISP. She unchecked all the boxes for Teredo and it started working again, but then they got checked again when she turned the computer back on. Leo says that Myrna needs to call up Verizon and find out what they think the problem is and why Teredo keeps getting turned on. She'll likely have to escalate the call because the average support person will have no clue what Teredo and IP tunneling is.

Leo thinks it's coincidental and there probably is something else going on, though.
