The BBC and other news outlets reported yesterday on the latest security vulnerabilities within Microsoft's Internet Explorer. What makes this report different than a lot of others is that we finally are hearing recommendations to actually switch browsers.
Right now it sounds worse than it is, but nevertheless, the risk is there. Experts claim that 10,000 websites have been exploited but that is only 0.02% of all Internet sites. The typical warning is to stay away from potentially nefarious sites such as bit torrent indexes and pornography, but as you may recall we have seen threats show up on more popular social sites such as Facebook and MySpace (see Worm virus from Facebook and MySpace).
Bottom line, no browser is completely safe all the time, but you can reduce your own risk by choosing your websites carefully, and by using a more secure browser such as Firefox or Opera. Google's Chrome and Apple's Safari are also options, though I don't believe they are as battle-hardened as Firefox and Opera.
