Meanwhile, AMD has finally admitted that the Meltdown and Spectre security flaws found by Google Project Zero affect its chips.

The discovery of security flaws Meltdown and Spectre led software companies to issue emergency fixes to prevent future system exploits. As it's a huge security flaw, you're advised to install the patches as soon as they become available for your machine.

"This set of vulnerabilities was perhaps the most challenging and hardest to fix in a decade, requiring changes to many layers of the software stack".

Intel and other chipmakers revealed on January 3 that potentially serious vulnerabilities nicknamed Spectre and Meltdown could allow bad actors to access the stuff on your computer or phone. What's more, the hit to "responsiveness", a more specific benchmark that Intel tested its chips for with the new updates, took a much bigger hit. Microsoft is working on this issue since it came to notice and has already released a security update recently on Windows 10 and previous version of Windows. In the document, Intel urges customers to delay additional deployment of these microcode updates and the company will provide frequent updates. And Amazon.com's Amazon Web Services chose AMD graphics processing units for a graphics design service announced in September. Brian Krzanich expects other industry players to follow similar practices: share security-related hardware innovations and help researchers of security vulnerabilities.

"End-users should continue to apply updates recommended by their system and operating system providers".

McAfee has rolled out an update to its endpoint security applications.

In the last few days, it got worse for AMD and Microsoft when the latter released a patch to address security flaws on AMD-based systems. The original blog post sent shares of Nvidia sliding in early trading Wednesday, and the company has since updated its post. The problem affects a staggering amount of modern information technology around the globe, including PCs, smartphones and servers that run widely used cloud computing apps.

The company also claimed that Windows 7 is suffering a slowdown of 6 percent, lower than the Skylake-s platform.

The level of transparency on these issues by the affected processor and software vendors is mixed, so businesses and users alike need to take public disclosures of the risks from these vulnerabilities with a grain of salt. These threats are merely new variations on an old theme. "Windows operating system updates to devices that have impacted AMD processors".

Some antivirus vendors have been quick to respond.

Lastly, the Intel CEO reaffirms the company's broader committment to user security, calling it an "ongoing priority, not a one-time event".
