**Its a scam. A well known and long running one. Microsoft will never ask for personal details (they already have them) and will never cold call you or send out anti virus messages.**Microsoft does not do that nor do they have partners who do that
See
the following for additional information about this and what to do and how Microsoft operates:

What should you do if you receive a questionable email?
DONT CLICK ON LINKS, Dont go to web sites that are suggested, dont give access, or volunteer information (usually
if you mouse over links they will not point to Microsoft)
1. Investigate the information.
Take
some time and check up on the information. Often sites like snopes.com can provide information on known chain letters and other scams and untruths. Do not click on links within the mail, but do go to that company’s website, and contact their customer service
reps via phone or online to verify the validity of the email.
2. Report suspicious activities.
If
you think someone has accessed your Outlook.com account, that the Live ID sign-in page looks fraudulent, or you receive an email that tries to confirm a password change you didn’t authorize, change your password immediately by going to: http://account.live.com.
Next, help ensure your PC has not been infected with a virus or malware by running a free full-PC scan.
3. Help the Outlook.com team identify new scams.
Click
on the Junk button in Outlook.com and select “Junk” or “Report phishing scam” to report it to the Outlook.com team. Whatever you do, do not reply back to the sender.
If
you think you might be a victim of fraud, you can report it.
