We spend lots of time figuring out the perfect computer passwords.

In this week's hot trends we find out that they are worthless and you will learn what else we need to do to keep our information safe.

Before we shop. Before we surf......we type in our computer passwords. They are often times birthday dates or a pet's name. And we feel pretty safe.

But at security giant mcafee they say hackers can break into your machine, one keystroke at a time. Emails, posing as a screensaver, can be a hack. If you open it, hackers can follow your every online move. Letter for letter...credit card number for number. It's the newest way hackers are getting inside your computer, finding and tracking everything about you.

Joris evers from mcafee says, "you get what we call a drive-by install on your machine, and without you knowing it, your key strokes are being captured, and you're being watched."

That is how data is stolen, and your credit history can be ruined. So don't worry so much about your password anymore.

Security experts say it's common sense that will protect you. Update your virus fighting software, and avoid any email or facebook post that looks unfamiliar

If you are running up to date security software on your machine, those password stealing programs will be detected and removed.
