This sounds like virus/spyware on the host or browser.  Does it happen 
to a Mac or Linux box running Firefox?

Don't use Windows/IE/Outlook.  If you must, patch often and use 
antivirus software.  Ideally, take those hosts off of your network until 
they're disinfected.  In any case don't move them to another subnet 
until they're disinfected.
