Switching from Internet Explorer to alternative browsers may make users feel more secure, but hackers are also making the switch.

Many people are switching from Internet Explorer to alternative browsers such as Firefox and Safari. Though that might make them feel more secure, the shift has also opened new doors for bad guys.

So forget the idea that just because you've switched to a new browser, you're magically safer. You may be for a time, but to stay safe with any software, you need to keep current with fixes.

Firefox holes
In a somewhat dubious recognition of Firefox's growing popularity, hackers have focused their attention on it, leading to a rash of newly discovered holes. The folks at Mozilla recently released two Firefox updates in less than six weeks, fixing a total of five critical security vulnerabilities. All five can be exploited by planting a poisoned JavaScript file in a Web site and waiting for you to stumble across it.

In an actual attack -- neither the Safari nor the Firefox bugs have elicited one so far -- a bad guy could take over your PC or steal your navigation history.
