FBI HomeLand Security Virus - How to Avoid Getting Hit

Never click on a website link in an email, if you really are not sure what it is, you can hover the mouse over the link and look at the status bar on bottom left to see what website it's really going to.  All it takes is to click on one bad link and this FBI virus will take over your computer demanding a ransom and locking you out for good.  It's easily removable with the right tools but very difficult for someone who has no computing experience.
