and if you enable it :
Some attack sites will try to infect your computer using a "drive-by download," which automatically seeks out holes in your computer's defenses and installs badware without any action on your part. Other attack sites will try to trick you into installing badware, frequently by showing fake security alerts or offering free stuff. Once the badware is on your computer, it might steal your passwords or account numbers, send junk e-mail (spam) to others, or try to extort money from you.
