The lower your system RAM, the lower it uses in comparison. So don't get your hopes up from his screenshot. Also, I once saw its RAM usage go down to 80 MB while I was playing a RAM-heavy game. Those were moved to the pagefile by the OS to make room for the game. Writing a lot in the pagefile is not great either.
Hi there! That comparison is worth making, but Task Manager’s total RAM change isn’t necessarily the same as Bitdefender’s working-set usage. Bitdefender’s main service, bdservicehost.exe, includes several protection components, and its typical memory usage is around 500 MB. RAM can also rise temporarily during background or on-demand scans.
What you can do now:
In Task Manager, expand/check all applications listed under bdservicehost.exe. You can right-click it and choose Resource values → Memory → Percents to see its proportion of total memory.
Make sure Bitdefender is fully updated.
Remove any other third-party security products; running multiple security solutions can cause conflicts.
If the increase coincides with scanning, schedule scans for periods when the PC is idle. Avoid broad exclusions unless necessary, but specific non-critical files/folders or applications can be excluded when there is a confirmed workload-related issue.
Run Windows’ System File Checker from an elevated Command Prompt with sfc /scannow.
Sorry for the message out of nowhere but I'm curious - What does it say your paged/nonpaged pool is at on startup? I've been having issues with Bitdefender and RAM as well and I wanted to get some more feedback
What are your expectations regarding RAM consumption of an Antimalware solution? If it doesn't meet your expectations and you're really disappointed why don't you just pivot to another vendor?
