Everyone Needs to Update their Windows ASAP, or Risk Being Locked Out of Their Computers, Security Experts Say

The WannaCry virus that shut down the UK health system this week is still making its rounds. It has now reached 150 countries and is continuing to spread.

It is expected that the hackers behind the ransomware will update it Monday, so it will be even more dangerous.

Computer security experts say that everyone should update their Windows OS, and back up all their data, because the virus is one that doesn't even need computer users to click anything; it is making its way around the internet searching for Windows that aren't updated. There is a known vulnerability in Windows that was exposed by an FBI data leak earlier this year. It seems hackers have based WannaCry on this known Windows vulnerability.

When a computer gets infected, all the data on it is encrypted and the owner no longer can access their files until they pay $300 in Bitcoin.
