Java is a hot item on the Web, because it allows a user to download foreign programs ("applets") over the Internet and run them in a local computer. But it could in theory expose a host machine to computer viruses and other digital mischief. Java's designers included an array of software guardians that screen each applet for admission and then keep it from running amok, but several computer experts have learned to use bugs in Java to bypass its safeguards. The flaws are being fixed, but security experts say more are likely to turn up.
