For security reasons your account is temporarily locked Your computer appears to be infected with a malware?

I got this after being on facebook for awhile. I have ran a malware scan and nothing came up. Also, other people in my household are able to log in on fb just fine. It's only my acct. How can I take care of this problem.I've changed the password but still nothing works.

That message sounds pretty bogus to me. It may just be something on a website trying to trick you into clicking something to download an actual virus. Can you post a screenshot of the message?

I've seen several people complain of this. It appears to be a legitimate Facebook message, but I'm not convinced you have any infections.

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. You will now see some drivers being loaded. There will be a pause at some point. This usually lasts for no more than 30 seconds.

If that's successful, download and run TDSSKiller.exe from Kaspersky Lab. It's tiny, and takes just a minute to run. It hunts down and kills a specific family of rootkits:

Regardless of the results, 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. Copy and paste it into your browser’s address bar, and press Enter.

After this, try rebooting normally. If that's successful, I recommend you run another full scan with MBAM. It will detect malware that wasn't running in Safe Mode.

You should now delete TDSSKiller.exe, 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.
