Is it possible to get viruses from a facebook application?

Yes.

Facebook applications can be provided by third parties and aren't vetted by Facebook.

They can present your browser with malicious code.

If the browser has a security flaw, that code can infect you with a virus.

Make sure your browser is kept up to date with security fixes, and run anti-virus software on your computer to help keep your system safe.
