1. Your security and your company’s security are at risk: There’s no other way to lay it out: if the security of Google, Yahoo, and around 20 other companies were compromised due to people still running IE6, then your security is at risk too. Upgrading after a hacker uses this exploit to steal your information is simply too late, especially if you hold sensitive customer data.

2. World governments are suggesting you switch browsers: Both Germany and France have issued warnings about Internet Explorer, asking citizens to switch to prevent the same type of breach that affected Google.

3. Even Microsoft wants you to drop IE6: The Microsoft Security Research & Defense Blog specifically addressed the flaw and the risk of attack by platform. The most important part of the post was that they “recommend users of IE6 on Windows XP upgrade to a new version of Internet Explorer and/or enable DEP.” This isn’t the first time Microsoft has asked people to voluntarily upgrade, but it is the first time that it’s been in response to an exploit or vulnerability. Think of it like a recall: would you keep driving a car that Toyota, Ford, or GM says could malfunction? Don’t make the same mistake with your computer’s security.

4. Not wanting to upgrade from Windows XP isn’t a legitimate excuse anymore: One way to delete IE6 is to upgrade your OS — both Windows Vista and Windows 7 run upgraded versions of the IE browser. We understood why people didn’t want to upgrade when their choice was Windows Vista, but now that a very stable, solid, and secure upgrade is on the market (Windows 7), there’s no excuse not to upgrade. Yes, it’ll cost you up front, but it’s far cheaper than having your data stolen.

5. This will not be the last massive IE6 security breach: This flaw was unknown before Google’s groundbreaking China announcement. And it’s not the first flaw ever found with the browser — there are at least 142 vulnerabilities in IE6, 22 of which are not yet patched. Would you use armor that had 142 weak spots?
