The BIOS includes instructions on how to load basic computer hardware and includes a test referred to as a POST (Power On Self Test) that helps verify the computer meets requirements to boot up properly. Otherwise, keep the existing version as long as possible. Same applies for Windows Updates, OS update, drivers updates, etc - upgrade/update IF you have issues which you know are fixed in the newer version or for some severe security issues. Any kind of update (no matter for what and who relesed it) can fix 2 issues but may introduce 10 more issues. Additionally, upgrading the BIOS (for any vendor) poses more risks because BIOS recovery is not that easy as compared to typical software updates IF something goes wrong. Updating just for updaing and just for using the latest verson is not solution. General recommendation I provide to users/customers is NOT to upgrade BIOS/UEFI unless they experience any kind of specific BIOS/UEFI issue. Personally, I do not recommend you do it unless you experience some issues with your existing BIOS and you are sure that the new BIOS will fix it. It's used for lots of PC vendors - check their website > Insyde is the vendor of the BIOS you have on your PC. Not sure what popped-up for the BIOS update - it could have been from HP Support Assistant, but this is not a virus. Hello you for posting in the HP Support forum.
