If you're one of the roughly 70 per cent of people using the world's most popular Google Chrome browser, you really need to make sure it's up to date.
Google quietly announced there are three active vulnerabilities in the browser, including one that is being actively exploited.
The holes have been plugged in the latest release of Google Chrome but that won't help you if you don't update.
In a blog post Monday, Google revealed older Chrome versions have three bugs that leave it open to malicious code.
Two of those were found by security researchers from Mozilla (who make the competing Firefox browser) and by Google itself.
