When you call the number 877-363-6747, which is displayed in alert, someone will answer who says Tech Support and speaks in perfect English without any accent. When questioned, they stated that their company name was 1 Good IT and started giving me the standard pitch of taking over my computer to see what was wrong and then fix it. Having done this before with other scams, I did not proceed further and hung up.
Though you may hear a voice speaking to you, this is still the same old scam. So stay vigilant and close any browsers that display these types of messages.

Finally, never call the numbers listed in tech support scams unless you just want to mess with them
