One of the world's largest provider of software is warning users to update their version after a security breach.

Microsoft issued a "red alert" to users warning them that they should update their operating systems immediately.

The company warned about two "critical" issues that could allow hackers to spread malware from one machine to another.

The new update will fix those issues. The company also said they had no evidence of any type of "attack" using the two issues.

"It is important that affected systems are patched as quickly as possible because of the elevated risks associated with wormable vulnerabilities like these," said Simon Pope, Microsoft's director of Incident Response. "Customers who have automatic updates enabled are automatically protected by these fixes."

 

If you don't have automatic updates enabled, you can search for the patch by typing "Windows Update" in the search bar from the system's start menu search bar.
