Microsoft has become the latest company to be attacked by computer hackers.
Microsoft found that a handful of computers, including Macs, were recently infected by malicious software.
“We have no evidence of customer data being affected and our investigation is ongoing,” said Matt Thomlinson of Trustworthy Computing Security, in a Microsoft blog post.

The blog post also highlighted the importance that other companies must be prepared to deal with similar attacks in the future.
Back in January, Facebook admitted to a security breach after employees visited a mobile developer site that was compromised. The website hosted an exploit, which then allowed malware to be installed on these employees' laptops, according to a blog post.
Facebook has claimed that no user data was from this attack, but security experts say this is difficult to guarantee.
Last week, Apple announced its computer systems had been breached by the same attackers that targeted Facebook. However, the company said only a few computers were affected and there was no evidence of data theft.
Microsoft claimed that its recent breach was from “malicious software using techniques similar to those documented by other organisations."
