The Spectre and Meltdown vulnerabilities, published on January 3, 2018, are byproducts of optimization techniques designed to increase the performance of modern processors. Fixes to prevent user-mode programs from exploiting these vulnerabilities within the computer's processor are being introduced by operating system vendors. Follow the best practices in this article to secure your computers and data.
Your ESET product protects against potential malware infection, but you should also follow the steps in Meltdown & Spectre: How to protect yourself from these CPU security flaws to secure your computers and data. You should also download the latest product modules for your ESET product.
Download the latest product modules for best protection
ESET has released an updated Antivirus and antispyware scanner (module 1533.3 in update 16680) for all consumer and business products. See the appropriate Knowledgebase article link for instructions to update your product:
- ESET Home products (NOD32 Antivirus, Internet Security, Smart Security Premium)
- ESET Business products (Endpoint Antivirus, Endpoint Security, File and Mail Security and Virtualization Security)
Note that a potential side-effect of the Microsoft patch can be reduced system speed. This is not due to the performance of your ESET product, but rather the firmware changes required to mitigate the Meltdown vulnerability within the computer's processor.
As of January 9th, 2018, Microsoft, Linux and Apple have released patches in response to these issues. ESET products are some of the first to offer full compatibility with Microsoft emergency patches that help protect against these issues.
We strongly encourage you to download the latest ESET product updates to allow the installation of these patches.
Keeping your ESET product updated is the best way to stay safe from threats that may take advantage of Spectre or Meltdown vulnerabilities. More information about these vulnerabilities is available in the following ESET publications:
- ESET Customer Advisory 6443: Spectre and Meltdown vulnerabilities discovered
- ESET Corporate blog post: Meltdown & Spectre: How to protect yourself from these CPU security flaws
