Microsoft has just released what it is calling "Fix It" software that was designed to protect Windows users from a critical hole in Internet Explorer that was being exploited by hackers. While this is all well and good, it isn't the big fix that everybody has been waiting for. Instead, this is merely a temporary fix until Microsoft releases a cumulative update for
Internet Explorer.
According to Trustworthy
Computer Director for Microsoft Yunsun Wee, the Fix It tool "is an easy, one-click solution that will help protect your computer right away. It will not affect your ability to browse the web, and it does not require a reboot of your computer. This will not only reinforce the issue that the Fix It addressed, but cover other issues as well, including four other critical remote code execution issues."
This isn't some minor hole, however. In fact, the vulnerability is so severe that the German government and security experts have been advising people to avoid using Internet Explorer altogether until the vulnerability is patched entirely, which won't happen until the larger update is released. That update, which has a severity rating of Critical, should come out any day now, meaning users won't have long to wait until they can get back to viewing the internet in peace.
This vulnerability, more specifically, was uncovered within the past week and could very well compromise the PCs of every single Internet Explorer user who visits a malicious site. The flaw itself is being actively exploited to deliver a back-door Trojan known as Poison Ivy. My recommendation is that you download the patch as soon as it is available so as to not risk any critical harm befalling your PC.
