Bitdefender CPU usage abnormally high

Thank you Alexandru_BD.

However, I have been given no access/link to the "open case". I have a case number, but I can only use it as a subject line in an email to your team---who NO LONGER REPLY!

This is why I get upset:

Tell me how this can be acceptable?

Got this issue too ... also cant right click on items to run as administrator ... if i turn off virus protection i can ... just to qualify this, the only file i cant right click on is an nvidia driver to run the update. Other files are ok, downloaded twice but same each time, cant get the menu up to selectr run as administrator.

Hello @Papa-Gus,

I'm sorry to hear this. Perhaps our engineers can help with the issue you have encountered. High CPU/RAM usage phenomenon has been reported on this forum previously by several members and in most cases, it was necessary for the technical representatives to perform remote sessions on the affected devices, to find the root cause. It is important to note that, such occurences are not affecting the mass of users and there can be various reasons behind this behavior.

Sometimes, depending on the system configuration and the active applications, the background scan might affect the computer performance. The system configuration and the applications differ from one computer to another, yet the mechanism is the same: there are applications or system processes that continuously access the resources and Bitdefender monitors this activity.

My recommendation would be to get in touch with the engineers for a more in-depth investigation.

@GjoksiThis appears to have worked for me, thanks @Gjoksi.

I've had bitdefender for about 2 years now. It was installed on my computer by some software firm that my moms company worked with, at first I could manage all the settings myself and I would just turn it off because it was always getting in my way, but then without ever asking they locked it with an admin password. I didn't really bother with it anymore since then until a few days ago when I tried to run a midi keyboard and it wasn't working because of some RAM issue and when I opened up task manager I saw bitdefender using about 60% of my memory, I contacted the software service but they didn't let me uninstall because of some policy. so I decided to delete their administrator account, ran some uninstaller software, switched over to AVG and all the issues have stopped.

don't install bitdefender it's an expensive way to slow down your computer.

Hi @Radek. S

Try running a custom System Scan setting it for High Priority. Once you create the scan, you can just use it for your normal System scan as it scans all the same Target threat types and Scan Options as the normal System scan. See if that works or helps. The first scan is always the longest and most intense, then Bitdefender indexes the files to make follow-up scan quicker and less intense.

Below are my scan results using High Priority.

Kind regards,

Scott

Nice job on the videos; you obviously know what you're doing, an advanced user :) :) I will review the 2nd video more to duplicate the settings you made in Windows Power Options/Advanced settings/processor power management, just for fun on my end :)

In general, Bitdefender over the years has had a history of a bit high CPU use during a system scan. That's why I only run it once or twice a month, and then run the quick scans weekly.

I believe BitDefender is one of the best, if not the best AV available. However, there is a problem that is being overlooked. A BD scan will drive the CPU to 100% and keep it there for what I think is too long. When I began to research motherboard beeps during scans I learned that the CPU was overheating -severely. I was running an Intel i7 960 3.2 GHz with 24GB RAM. My system was old and I simply removed the side of the case and turned a house fan on the CPU. Even then, I had to use windows power settings to limit the CPU to 60% utilization during a scan (Control Panel, Power, Advanced power settings, Processor power management). This kept the CPU below 78 degrees C. As I said the system was old and it had a fair amount of dust accumulated.

I am fortunate to have been able to recently build out a very nice new system: It is an Asus ROG Strix X670E-F with 64GB 5200 memory. The AMD Ryzen 9 7900X has 12 cores and 24 threads. Bit Defender pushed the CPU to 96% utilization. The Asus BIOS allows me to limit CPU resources based on temperature and I have it set to maximum 85 degrees C (or maybe 80, I'd have to reboot into the BIOS to check exactly), so it keeps the temperature down. In other words, even the best of systems are vulnerable to this level of demand on the computer.

I really don't know much, but it seems to me that BD needs to provide users with some method of throttling the resource demands that the BD AV scan places on computers. It seems to me that driving systems this way could easily damage computers whose owners have no idea what is happening during a scan. The BSOD is probably saving their systems.

Anyway, I really do like BD very much. But couldn't a product this good go one more step and provide a 'scan priority level' or something to throttle resource usage a little bit?

For those of you still having this problem, I'm running the latest version of Bitdefender, and the ONLY time I experience the problem is if I reboot (or start) my computer and have an active external drive plugged into a USB port. I'm just guessing, but I think Bitdefender is detecting the external drive on start-up, and immediately performing a full scan on the drive (for your protection). It took me a while, but then I realized this problem only occurred when I did a reboot with an active external USB drive attached. When I shut down, turned off the external drive, and powered up, no problem. And no, the problem does not happen again once the external drive is turned back on (or if powered through the USB port, plugged back in). Why Bitdefender doesn't immediately start a full scan on the external drive once it's started is a mystery to me, but it doesn't and there is no problem. (For which I am glad.)

I can understand why those who can't seem to fix this problem are frustrated. I would be as well. All I know is what my experience has been, and when working properly, Bitdefender is, for my money, the best program of its type anywhere. (And I owned an internet IT company for 16 years.)

I hope what I've shared is helpful to others.

Having this issue for some time now, but it only happens on boot and after 2~3minutes it goes to 0% CPU usage. After reading someone here, I rebooted and tested removing the USB flash drive I always have connected, with task manager open, as soon as I removed the Flash drive, CPU usage went to 0%. I also have Special Offers, Scan DVD/USB disabled. Flash drive is a Sandisk 128GB USB 3.1 filled with huge mp4&mkv files.

As a side note, I have been using Bitdefender since they exist, I just cant recommend a more complete and efficient security solution than Bitdefender, and I actually recommend it to everyone I know.

Same , its use 44% of my cpu on a i9 , my computer was so long.... no change after many restart i dont have usb flash or disk , even if i shut down the réal time protection ....no way ....iv juste desinstall completely an now my computer works fine ...so goodby ....refund......
