MALWARE PROTECTION IN OFFICE 365 

Malware is comprised of viruses and spyware. Viruses infect other programs and data, and they spread throughout your computer looking for programs to infect. Spyware refers to malware that gathers your personal information, such as sign-in information and personal data, and sends it back to the malware author. 

Microsoft Exchange Online Protection allows the user to combat malware in your email messaging environment. (Exchange Online Protection helps protect your on-premises mailboxes and is also the malware filtering solution for cloud-hosted mailboxes in Exchange Online.)
