Hi, my name is ***** ***** I'll be happy to help you with this!
This message is NOT legitimate. This is a scam that is going around right now where you will encounter a message saying that your computer has been hacked or you have a virus or something along those lines and that you need to go to a website or call a number. The whole thing just a ploy to either installed malware on your computer or to get money from you.
Sometimes these messages will claim to be Microsoft, but this is always a lie. Microsoft has released a statement saying they never contact customers directly about computer issues and that all contact must first be initiated by the customer.
If you receive these messages in the future, simply close them out.
If it won't let you close it out, then you can just hold down the power button on your computer for 5 to 10 seconds to do a hard shutdown. Once you restart your computer the message should be gone.
If you have any other questions on this, just let me know and I'll be happy to answer them for you.
NOTE: If you have no further questions, please use the rating box at the top of the page to rate the answer at least 3 STARS/OK SERVICE or better so that I receive credit for assisting you.
