Bitdefender is antivirus software that protects every computer in your organization by stopping malware intrusions, network hackers, and tricky file-less attacks. Sometimes, some users find that Bitdefender takes up high CPU usage.
Why Does BitDefender Take up High CPU Usage?
Bdservicehost is the .exe file associated with the BitDefender software and contains key BitDefender virus protection components. Although the file size is not large, it does use an unusual amount of CPU and disk space in some cases. When this happens, you can optimize RAM and disk, or try to reduce bdservicehost.exe CPU/disk usage.
Other times, it might be because you have multiple programs running on your device. As it stands, opening resource-intensive programs or browsers such as Google Chrome also increases Bitdefender’s RAM usage.

In addition to corrupted or missing system files, disk errors can also be the cause of this issue.
