ESET can help stop malware that in the future may use Spectre and Meltdown vulnerabilities


ESET products are some of the first to offer full compatibility with Microsoft emergency patches that help protect against these issues. Apple has also released mitigations for the macOS, OS X and iOS operating systems.

We strongly encourage you to download the latest ESET product updates to allow the installation of these patches.

This is the best way to stay safe from threats that may take advantage of Spectre or Meltdown. For more information on these vulnerabilities, refer to our customer advisory and WeLiveSecurity article, Meltdown and Spectre CPU Vulnerabilities: What You Need to Know.
