If you are running Windows, I would recommend reading this. If you are running Windows 10 this is most likely been patched in an update, however always good to read
You've probably seen this around discord, but the WannaCry ransomware is out there, but it was shutdown due to a killswitch. The killswitch would search for a list of 30 domains and if 1 of them was active, it would stop spreading. Luckily, a researcher bought 1 of the domains and stop the ransomware! It might come back though, so get the update.

The patch is available for Windows versions from XP-10, and Server 2003-2012:

This will have most likely been installed on your computer, especially if you are running Windows 10, however if you are not, it might be good to check if not.
