Intel's Spectre and Meltdown headaches continue

Meltdown Spectre in Chromebooks

Computers Here’s all the Chromebooks that are vulnerable to Meltdown Chris Mills

The chipmaker said that fixes for security issues in its microchips would not slow down computers, rebuffing concerns that the flaws would significantly reduce performance.

Like most organizations, chip manufacturers long have prioritized speed over security", said Ryan Kalember, senior vice president of cybersecurity strategy at Proofpoint, "and that has led to a tremendous amount of sensitive data being placed at risk of unauthorized access via Meltdown and Spectre.

Microsoft took the rare step Tuesday of detailing exactly how its latest security fix would impact your computer's performance - down to the millisecond. Windows 10 is only on a quarter of PCs.

Depending on how you use your computer, you may not even notice a difference.

Then, in the final analysis, we'll have to wait and see just how much the entire internet slows down after patching every processor in the world. For example, all fonts in Windows 7 and 8 are rendered on the kernel, the software that controls the processor. Intel was particularly hard hit by the exploits, forcing the firm to double down on security updates for them.

United States manufacturing surges in December, ISM shows
The Employment Index declined 2.7 points to 57.0 in December, indicating expansion for the fifteenth consecutive month. The group's New Orders Index came in at 69.4%, the highest since January 2004 when the index registered 70.6%.

Windows customers aren't alone.

A wide range of security advisers agree that now that the exploits have been made public, it is only a matter of time before cyber attackers try to make use of them, and for this reason, enterprises can not afford to waste any time applying security updates from suppliers as they become available.

AMD is clear that its processors, including its Radeon GPU range is not affected, because the way their chips operate doesn't involve speculative execution, and therefore, the problem doesn't apply, though there is some evidence that Spectre's newest form could be an issue and AMD isn't about to get Intel type egg on its face. Apple is also planning an update for its computers and promises the slowdown will not be noticeable.

AMD CEO Lisa Su tells Yahoo Finance the Austin, Texas company is quickly working towards a solution for the Spectre security flaw. In the short-term, computers with Intel chips are more likely to suffer from performance issues, leading to compromised servers for cloud platforms, however, it's still unclear what the longer-term, more far-flung ramifications are for computer users overall.

Microsoft said a in customer support blog post it had received complaints from AMD customers that their machines stopped loading the Start menu or taskbar after installing Windows operating system security updates.
