Acer has patched a serious flaw with the firmware on certain of their Notebook computer that left the trusted Secure Boot, Trusted Platform Module (TPM) chip and Unified Extensible Firmware Interface (UEFI) security features vulnerable to deactivation.

Infected devices include “Acer Aspire A315-22, A115-21, A315-22G, Extensa EX215-21, and EX215-21G” but you should check your Acer laptop with the manufacturer’s website.
Get it fixed if you or your team have an affected device.
My advice: Either you or your IT support need to check whether these issues impact your systems. You need to have a master document that details your systems, hardware, software, online, networks, back-ups, suppliers etc – so when cyber security (or operational) issues arise you and your support teams can quickly check if you are affected. From there you can take fast, effective action.
