So, yes, AMD processors are safer than the chip families - Intel, POWER, ARM - affected by Meltdown.

In news related to the above, MSI has pushed out BIOS updates for its range of Z370-series motherboards. Windows 10 is only on a quarter of PCs.

Who is impacted by Meltdown & Spectre? The browser patches are intended to stop the attack vectors through the browsers.

Symantec alerted its enterprise customers of an incompatibility with the ERASER (Expanded Remediation And Side Effect Repair) Engine found in some of its products. These numbers can give you a more concrete idea of how much you'll be affected. Customers can take advantage of built-in antivirus protection, Windows Defender Antivirus, for Windows 8.1 and Windows 10 devices or a compatible third-party antivirus application. "In a blog post, Microsoft's executive VP of Windows and Devices Group, Terry Myerson said that 2016-era PCs with Skylake, Kabylake or newer CPUs will expect to see single-digit slowdowns in certain settings".

Finally, keep in mind we're still in the early days of dealing with these fundamentally different security problems. However, last week, Amazon, Apple, Google, and Microsoft said that the fixes they'd been applying so far weren't creating major device slowdowns. The following outlines our current efforts to remediate our systems and work with Amazon Web Services (AWS) to make sure we're tackling this issue from all fronts.

What systems require patching for vulnerabilities?

Last week, two 'speculative execution' bugs came to light affecting many processors released over the last ten years. The same numbers are reflected by PCMark and 3DMark benchmark.

The patch is causing systems to reboot more often than normal, specifically for users running its older Broadwell and Haswell CPUs for both client and datacentre.

Where to go from here? Now Microsoft seems to have adjusted its outlook, particularly for general PC use. This is by design to protect critical security information like usernames, passwords and encryption keys.

Meltdown breaks the most fundamental isolation between user applications and the operating system.

"We are working quickly with these customers to understand, diagnose and address this reboot issue", Shenoy said in the statement.

Nvidia has provided updates to GeForce, Quadro, and NVS driver software, as well as its Tesla driver software, and its GRID driver software.

Watching the order in which the plates land lets observers infer the data, he told Reuters during an interview on Wednesday at the tech industry's CES conference in Las Vegas.
