High CPU, Power Usage

Windows 10 Home, v.21H2, Build 19044.1889

Bitdefender Total Security, Build 26.0.25.84

Since the latest update, Bitdefender Total Security, Build 26.0.25.84, I've been hearing my fan run high. Checking Task Manager I see the "bdservicehost" process running constantly at 20-25% CPU usage, at the LEAST, occasionally greater, which means a steadily greater power consumption, and that translates into a significantly shortened battery charge period. Anyone else having this experience? Any fix in the works? Thanks.

Hi @WWJ

There seems to be an issue with the latest update, including with myself. Please see Alexandru's suggestion to contact support from this thread:

Same issue, noticed it this morning.

WWJ

@gfmock Your performance looks virtually identical to mine, and seems to be at least a fairly widespread issue. You'd think it would be obvious with a reasonable degree of testing, which makes me think BD doesn't do much if any before these update releases. Unfortunate.

WWJ

@Scott Have you tried that?

Scott

@WWJ yes, it's what I'm running now :)

WWJ

@Scott Yes, that seems to have worked for me, too. A bit of clarification, though.

In Programs and Features, after selecting Bitdefender Total Security > Uninstall, it was sufficient for me to perform just a reinstall (operation on left) rather than the uninstall and install:

After the reboot, the installer downloaded the program, itself. I didn't need to do so manually from Bitdefender Central. The build I now have running is 26.0.23.80.

Thanks for your help! 👍️

@gfmock bdservicehost process now back to nominally <0.5% CPU and very low power usage:

Nice to have a quiet computer back again. ☺️😴

Thank you for posting back your results, I'm glad it helped 😊

Also, that it could be done from a Windows reinstall. Good information, WWJ 😊

@Scott BTW, I find my build info at the bottom of the screen that appears when I click the lifesaver icon, but I can't find the popup with full product info that you show in your post:

How do you get there??

Scott

Right-click the system tray icon, About :)

WWJ

Ah, of course! Thanks again.

Scott

You're welcome :)

I observe the same issue!!! I wasn't able to disable automated update to build 26.0.25.84. I had to uninstall antivir. :-(

WWJ

@kw_user Did you ultimately get it fixed?

elstaqub

The latest update, 26.0.25.86, fixes the problem for me.

Scott

@elstaqub thank you for the notifications you posted in other threads, as we also had another member confirm it here: https://community.bitdefender.com/en/discussion/comment/315357/#Comment_315357

Edit: Just a reminder, BD releases its updates in staged rollouts. So your region may have this update ready to download, or it may be 2-3 days later, depending on where you're at. In the central US location, my updates arrive about 1 week later after the first mention of the update occurring. Updates can also be tracked here:

I removed BitDefender from my computer.

WWJ

@BDiff Thanks for that report. I'm going to stay at 26.0.23.80 for awhile.
