Hi Member,

This issue is very common with most of the people who use bitdefender. But, this seems really weird as per the specification of your PC. Bitdefender should have run smoothly in your case.

System requirements for bitdefender are as below :

Try the below solutions :

1) Kindly go forward and uninstall the bitdefender product via bitdefender product removal tool :

https://www.bitdefender.com/site/view/uninstall_consumer_paid.html (select uninstall tool as per your version)

2) Kindly remove your windows device from bitdefender central account :

https://www.bitdefender.com/consumer/support/answer/2795/

3) Restart your PC

4) Open run command (windows icon + r) & delete temporary files from below 3 folders one by one :

type temp, delete all files in the folder
type %temp%, delete all files in folder
type prefetch, delete all files in folder

5) Now, reinstall the bitdefender product again (either from central or directly from their website)

6) Restart the PC & check if the issue persists.

If the issue persists, generate bitdefender logs (https://www.bitdefender.com/consumer/support/answer/1922/) & kindly drop an email to bitdefender support at [email protected] .Briefly explain them your issue and also attach the bitdefender logs in the same mail. Also attach the new screenshot from task manager. Wait for their response.

Response may be delayed due to less staff and covid19. Rest be assured, they will reply back asap.

If this helps, kindly mark answer as agree/ accepted

Regards

Has this issue ever been fixed by Bitdefender? I've been searching tonight and find multiple threads on multiple sites about this issue that has apparently been occurring for at least 5 months and the only responses seem to be "we know it's an issue".

I even turned off Bitdefender Shield but the Bitdefender Virus Shield bdservicehost is still taking up 90+% of the cpu (and no scan is running).

I never had this issue with TS 2020. It's only been since "upgrading" to 2021.

It is absurd to ask people to go through the procedure above for what is clearly a known bug in Bitdefender that has still not been fixed.

If it keeps happening, I will be stopping with step 1 above (uninstall Bitdefender).

Just posted about this on another thread. BD has been taking 16% of CPU for HOURS now today(been going on for quite a while beyond today) and upping my CPU temps by 15 degrees, while continually thrashing my hard drive. This occurs sporadically but often and for LONG periods. When it's not happening, BD takes less than 1% of my CPU.

I tried Flexx's suggestion above but nope, as soon as I reinstall it, off we go again. Only way I was able to stop it was to turn OFF the AV Real Time Protection and then REBOOT. After the reboot, things would go back to normal. But of course this defeats the purpose of this software, so I've uninstalled BD for the time being and am test driving something else as I cannot let this go on. This PC is an i9 10900 so anything should NOT be going on for HOURS. This type thing put a hurting on my laptop.

Based on the longevity of these threads, BD doesn't seem interested in fixing this.

EDIT

So I just checked my daughter's PC and laptop and BOTH are slow as molasses because on her PC, BD is taking OVER 50% of her CPU and similar on her laptop with this SAME ISSUE.

Gonna have to uninstall it there too as she uses her laptop for school.

It wasn't like this in late JAN/early FEB. One of your recent updates has caused this. PLEASE ROLL IT BACK until you can fix this issue.

Chuck_IV · March 2021

Just posted about this on another thread. It has NOT been fixed and is getting worse. On my top of the line PC with an i9 10900, BD Total Security is taking over 16% of the CPU, causing my hard drive to go crazy and raising my CPU temps by over 15 degrees for HOURS ON END. Then it will magically stop for a little while, then start up again. On my daughter's PC AND Laptop, BD is using OVER 50% of her CPU.

ONLY way to get it to stop is to disable the AV portion of it and reboot. But of course that defeats the purpose of this product. I have tried Flexx's suggestion up top but it doesn't help. As soon as I reinstall it, off we go again with the high usage. The 2020 version never had this issue, only the "new" 2021 version does.

I have no choice but to uninstall it and move on, until I hear this is fixed, as my daughter uses her machine for school and she can hardly do anything with the CPU usuage that high.

Really seems they either don;t know how to fix it or aren't concerned about it,.

ritwik_zz · March 2021

Flexx's suggestion worked for the CPU, memory usage still the same, but I don't think its an issue now.

Another issue is whenever I am gaming, the bdservicehost disrupts my ping a lot. I can't even turn it off for some time. Please do something else I'm not buying this again.

Having same issue. Will have to go with another product if a resolution is not found quickly.

I tweaked a few settings in bitdefender a month back and after a couple days maybe I also stated having same issue, I had 8gb ram but overtime it would start eating my ram making my PC sluggish. Now after few tweaks here and there when I disabled "silent update" Under "Settings - Update" Tab and Restart PC, I didn't face the issue again, though after every few hours I get update notification, but its better than having my PC slowed down altogether. Don't if it was just me or not but Hope it helps others...

NeilMc · October 2021

Same deal, everytime I'm doing something that requires fast processing on CPU and disk bdservicehost jumps in with 15+ % CPU and high disk and effectively kills what I'm doing. Jobs taking 10 times longer, 5 hours instead of 30 min. Hopeless, will be looking at other products definitely.

Claudette · December 2021

This is happening to me at least twice a week now. My PC freezes for at least a day and a half while BD is downloading virus shield and I can’t get any work done. I’m going to uninstall and abandon this product.

kissis · December 2021

I'll also be uninstalling BD after 6 years of use. This issue has continued to plague my system. This is very upsetting because I have roughly 677 days remaining for my account... It's just not worth it anymore when I'm on this site every couple of weeks because my system takes an extended nose dive because of updates on BD.

Frddy_Z · December 2021

I am running it on a new Mac mini M1 with 8GB of RAM. No matter what I try I cannot get this pig to use under 750MB. This is really old.

Danger · January 2022

Just got a new laptop 16gb ram, yet bdservicehost is taking up half a gb of my memory every second. Does it really need that much or are they also mine for cryptocurrencies or something?

BenderOvr · January 2022

WTF Bitdefender... getting worse than ESET and that's pretty bad.... Can we please get some kind of resolution for this issue or do we all need to uninstall?

Processor AMD Ryzen 5 3550H with Radeon Vega Mobile Gfx, 2100 Mhz, 4 Core(s), 8 Logical Processor(s)

Besides Brave on this webpage, nothing else is running. No scans, no updates.... just EAT....

JonatanAntin10 · January 2022

Haha your'e cute...

I think that mine is a record braker:

Its a lenovo yoga c740 with i7-10510U, 16GB ram...

I have only recently bought the product (used mcafee until now). One of the reasons I've initially bought it, was the great amount of product reviews stating that bitdefender has little to no overhead on the system - but as I now see, I was fooled by misleading reviews.

I hope bitdefender fix it soon, before ill found out a product that actually works as it states.

Rab_M · January 2022

Hi, I recently ran into this same problem my cpu was at 56c while idle or lite load

Asus x570 F-Gaming 3900x 12 core 64gb Ram 5700xt 8gb oc Graphics

Bitdefender poped up on screen and asked if i would like to change the profile of how the computer runs

so i went into the profiles and changed it from Auto To Movie editing the movie profile to limit all background operations & limit windows update :)

Now my computer runs idle or lite load 34-36c :)

katherine · January 2022

same issue ... on both memory and CPU temp.

I tried the switch to game mode thing a while back and it worked for about a month but then the memory issue started creeping up again. I just did a fresh install following all the proper instructions, game mode is on, and the memory usage runs 546.2MB ridiculous. I am tired of wasting time on this.

I'm not going to post a log for the simple fact that CLEARLY this is an issue experienced by many users and there hasn't been a single comment on it from Bitdefender.

My license expires in a month and I think I'll let it go.

katherine · January 2022

Just finished a LiveChat with a Bitdefender Agent and wanted to share the results:

I was running at 546.2MB as I noted above.

To help with diagnostics I was asked to turn off Advanced Defender Threat and Bitdefender Shield (both under the protection tab ... just check the modules in there). I turned off Advanced Defender Threat first and my usage dropped to 193MB. Then I turned off the Shield (under the antivirus) and my usage dropped to 138MB. I re-enabled both modules and my usage is holding steady at 173MB. Not a perfect solution but thought I'd share it.

I also mentioned to the agent that it would be worthwhile for Bitdefender to let the community know what they are doing about this issue as there is a lot of unhappy chatter about it. The Agent offered that if they had a solution it would be in the top level documentation. Not sure that helps. If the problem comes back quickly, I might still let my license expire.

JohnWilloughby · January 2022

Anytime a company asks me to "uninstall -> delete some files -> reinstall -> see if that helped" I translate that into "Uninstall -> load a similar program from a different vendor". And I do appreciate the "fix' Katherine just shared but that's a hack, not a solution. Hey Bitdefender, fix this! I've seen *a lot* of posts about this topic when I was searching for an answer, which apparently doesn't exist yet.

RomKnight · September 11

I just restarted my PC because bdservicehost was using 9GB+ of memory. After a couple of hours, it is now at 1.2GB (13% of the memory according to taskmanager).

I noticed this because now I have programs crashing due to lack of memory and this is a recent issue.

I'm a paying customer for 5 licenses of Total Security version for so long I don't even remember anymore and all this time any hiccups.

Is it time to change AV? Plenty of options and way lighter too, because even in normal conditions, bitdefender always used more resources than a lot of other options namely, memory.
