Critical Alert – 1/3/2018 Windows Security Update
Researchers revealed serious flaws in modern processors that could affect practically every Intel computer released in the last two decades — and the AMD and Arm chips in your laptops, tablets and phones, too. CNET reported 1/4/2018 and other IT security sources.
Microsoft released a patch to address a number of issues, including a reported CPU vulnerability issue on Wednesday 3 January 2018.
Microsoft is ensuring applications are compatible before the deployment of the fix with a compatibility flag controlled by a windows registry key, which will have to be put in place by the respective AntiVirus vendor.
If you have VIPRE Antivirus :
