Worm Infects Windows Computers Worldwide
According to news reports, tens of thousands of Windows computers throughout the world have fallen victim to a ransomware worm (a type of computer virus) that encrypts files and documents and then demands a payment for the decryption key.
How the worm spreads is not yet clear but you should be very careful about visiting new websites and opening emails. If your Windows computer is up to date with the latest updates from Microsoft then you are safe from this worm.
