Ditch Java (if you can)
Oracle’s Java is no longer critical software for many PC users. That’s a good thing, because it’s been the source of a veritable flood of security vulnerabilities. Some security experts are calling for Oracle to rewrite Java. In January, 2013, the Department of Homeland Security’s US-CERT (Computer Emergency Response Team) recommended that all PC users disable Java unless they absolutely need it.
The best way to find out if you can live without Java is to delete it completely. Seriously! Go do it right now. If a website or software prompt demands Java in the future, simply reinstall it—but you probably won't have to.
