Slowly takes RAM from my Windows 11 via bdservicehost until the computer freezes

@H00n ,

Welcome to the Bitdefender Forums. There have been scattered reports over the years of excessive memory usage, but I have never experienced it, nor is it very widespread. Normally Bitdefender will use about 600 to 800 MB of RAM, except when scanning. I just checked my Task Manager, and all of its processes are using about 700 MB. My computer has been on for five hours.

Often the issue is the particular configuration of a user's computer that is responsible. I recommend working with the support engineers by providing whatever logs are requested.

Have a great day.

Regards,

Phil

Hello,

During on-demand or background scan performed by Bitdefender it is normal for CPU, RAM, and disk usage to increase. Scanning involves intensive processes that require significant resources to analyze files, folders, and system areas for threats. The temporary increase in resource usage that occurs during the Bitdefender system scan and quick scan is normal. It does not significantly slow down Windows and should not be interpreted as an issue.

Although bdservicehost is designed to operate efficiently, some users have encountered higher than expected CPU and memory usage and we have seen threads on this topic in the community as well. You can use the search function to find similar topics. I think we must always take into consideration the user context. At first, it may seem that there's a problem and rightfully so, if the usage goes through the roof and the performance is affected, chances are something is not right or there is an incompatibility between the system and the antivirus. But before making any assumptions, there is always a checklist to follow.

Sometimes, even adjusting the scanning options can make a huge difference. For example, you could schedule scans during periods of low computer usage or decrease the scanning frequency. Otherwise, if the antivirus is scanning the whole device whenever you have 20 tabs open and you are also streaming, writing emails and working in photoshop, surely you will notice a decrease in performance. Setting exclusions can also help, if the problem appears only when using a certain program or when compiling software into a particular directory, etc. add those specific apps and the folders they are accessing to the exceptions list in Bitdefender.

So, whenever we notice that we get high CPU or RAM usage in conjuction with the antivirus, we might be inclined to believe that there's something wrong with the antivirus itself, without taking into account what else is happening on the device that may result in this high consumption. Obviously, the developers wouldn't create a software that is hogging resources and any vendor would get tens of thousands of complaints if that was to happen, but there is a general consensus that after installing a security software, the computer will slightly slow down, which to a certain degree is normal. It is whenever this usage exceeds certain limits that we must ask ourselves what is causing the high resource consumption and there can be numerous reasons, as the support article on this topic explains.

My advice would be to continue to investigate this behavior punctually with the Support engineers.

qBittorrent v4.6.2 is the program and 200+ task in it.

Without qbittorrent, bdservicehost using ~500MB ram. If I started the qbittorent, the memory usage is slightly rising all the time. I don't notice this consmption any other program or services.
