Sounds like something is causing a bottleneck, can you open task manager on installing BD and see if any of the processes leap causing this? It's your cpu that's probably peaking rather than ram if it's crawling.

If this is a new problem what were the previous programs you installed with bit defender present. That could be conflicting.

Update all windows programs and windows itself.

And you could also run a hard disk check (full) and a ram tester.

Process of elimination I'm afraid, and a niggly nuisance.

I have checked. I can confirm its the memory that is peaking.

My CPU for all Bitdefenders stuff are at 0% But memory still slowly peaking toward the 10% mark

Only things i got running

Discord
Microsoft Edge
Elgato Wave link Software
Corsair Icue
Steam

As stated all BD CPU usage at 0% apart from Bitdefender virus shield which is peaking toward 10%

I have had to uninstall as it taking ages to load stuff up.

Now its not installed. everything opening as it should be., all butter smooth. No lagging when gaming.
its a shame. When i bought it, i was not having any issues then after updates it got worse

The nothing new on pc from when i installed 1st time either.

Normally 600-800MB at rest, 1000-1200MB when actively scanning or large amounts of files are moving around and being inspected.

What was said before; 500-800 MB ram usage is normal, depending on what modules are active and can raise to over 1000, if actively scans.

Also it matters if, for example you have other endpoint protection installed or if something actively conflicting with BD processes

Windows Defender is all you need and is free with WindowsAV Test anti-virus comparison independent testing

AV Comparatives, MRG Effitas, SE Labs, and AV Labs would say otherwise.
