Bdservicehost is a .exe file associated with BitDefender software and contains critical BitDefender virus shield components. While file size isn’t much, it does use an abnormal amount of CPU and disk space in a few instances. When this happens, you can optimize your RAM and disk or try to reduce bdservicehost.exe CPU/disk usage. If you are experiencing this issue, feel free to consult our all-inclusive guide on contending with bdservicehost.exe-related excessive disk/CPU resource consumption.

Why is BitDefender taking up so much memory?

There are a few things that may trigger it. Sometimes, the application running in the background may start it. Other times, it could be because you run multiple programs on your device. Case in hand, opening a resource-intensive program or browser, such as Google Chrome, will also increase Bitdefender’s RAM usage. This spike happens because the program’s background scanner also runs checks on cache files and temporary files created by programs in real time. Some associated problems include:

Bdservicehost high memory usage Bitdefender virus Shield high memory usage Bdservicehost.exe high disk usage Bitdefender GravityZone high memory usage Bdservicehost 100% disk usage Bdservicehost high CPU

Each of these issues is a variable indicating a lot of memory usage. No matter the cause of the spike, here are a few solutions to adopt.

How can I fix the bdservicehost high CPU and disk usage error?

1. Perform an SFC  scan

Check to see if the CPU/disk usage has subsided. If not, continue to the next step.

2. Perform a DISM scan

3. Perform a clean boot

This is effective against bdservicehost high memory usage. SPONSORED Note: A clean boot allows your computer to use only the required number of programs and drivers. In this state, it becomes easier to pick up on interference by background applications.

4. Change processor scheduling

Note: You can prioritize running applications over background ones by changing processor scheduling. As long as you are not running BitDefender actively, disk/CPU usage by bdservicehost.exe will be limited.

5. Stop and Disable Superfetch

Superfetch, ironically, is a program that is designed to optimize your RAM and minimize boot time. However, in many instances, it takes too much processing power away from your PC to allow for a smooth experience. In these instances, it is wise to disable Superfetch, especially when disk and CPU space is already scarce. However, if disabling Superfetch makes no difference, you should switch back.

6. Reset the Virtual Memory

Virtual memory allows you to use hard drive space as RAM, but it is much slower than RAM. To avoid a system crash, resetting virtual memory is recommended if your disk usage exceeds normal levels.

7. Clear Temporary Files

Does Bitdefender use a lot of RAM?

Generally, it is not very resource intensive, but as discussed above, this will depend on the number of available operations. It usually will run background scans on open applications. So, resource usage may spike if you have many concurrently running programs. If you have bdservicehost high memory usage on your computer’s resources, you are in the right place. You can follow any of these six solutions to diagnose this problem or lessen it to an extent. However, a reinstallation is worth trying if disk/CPU usage remains untenable. Failing that, it might be time to get your drive or RAM checked. If you found this helpful guide or have any more valuable tips to add, feel free to let us know in the comments section below!
