What can I do about the Meltdown and Spectre flaws?
Users can do little to avoid the security flaws apart from update their computers with the latest security fixes as soon as possible. Fixes for Linux and Windows are already available. Chromebooks updated to Chrome OS 63, which started rolling out in mid-December, are already protected.
Android devices running the latest security update, including Google’s Nexus and Pixel smartphones, are already protected. Updates are expected to be delivered soon. Users of other devices will have to wait for the updates to be pushed out by third-party manufacturers, including Samsung, Huawei and OnePlus.
An update from Apple on what is needed for its Mac computers and iOS devices is expected.

Microsoft has issued an emergency security patch through Windows Update, but if you’re running third-party antivirus software then it’s possible you won’t see that patch yet.
A firmware update from Intel is also required for additional hardware protection...
Ensure you have the latest Windows 10 updates and BIOS updates from Dell, HP, Lenovo, or one of the many other PC makers. We’re hoping Microsoft or Intel creates a simple tool (they have a PowerShell script right now) to check protection for both the firmware and Windows updates, but until such a tool is available you’ll need to manually check or get familiar with PowerShell. Here’s a quick step-by-step checklist to follow for now:
- Update to the latest version of Chrome (on January 23rd) or Firefox 57 if you use either browser
- Check Windows Update and ensure KB4056892 is installed for Windows 10
- Check your PC OEM website for support information and firmware updates and apply any immediately
