How can I protect myself?

If you maintain sensitive data on your computer that you think an unscrupulous adversary might want, you should disable Java and JavaScript, as well as not installing plug-ins, except from well-known
vendors. 
If you don't disable Java or JavaScript, think twice before visiting a Web site belonging to a person you don't know or don't trust. Of course, some people will be perfectly happy just living with the risk. 
You can reduce the damage caused by a potential security breach by taking common-sense precautions like backing up your data frequently and keeping sensitive data off your Web-surfing
machine.
