I don't know if this is a genuine Facebook message or some kind of scam. If it's genuine, you could attempt to disinfect your computer, then have another go at logging into Facebook.

Try this:

Firstly, boot your computer to the Safe Mode menu screen. You do this by repeatedly pressing F8 as soon as you boot up. Once there, use the arrow keys to highlight Safe Mode with Networking. Continue to boot from there, by pressing Enter.

Now download the free version of Malwarebytes' Anti-Malware (MBAM). Install it, get updates and run a full scan (still in Safe Mode). This is a direct download link:

After that, boot normally and run another full scan with MBAM. It will detect any malware that wasn’t running in Safe Mode.

If the problem still exists, download and run the free Kaspersky Virus Removal Tool:

You should now delete the Kaspersky Virus Removal Tool, as updated versions are often made available. Malwarebytes' Anti-Malware can be easily uninstalled, should you wish to do so, but it may prove to be beneficial in the future.

Hope this helps.
