high CPU load (100%), Windows 10 home, Bitdefender Total Security and 87


Dear all,

I have got a real problem with Bitdefender Total Security, current version ( and 87) and today's viruses bases.

Since yesterday there are 3 machines with 100% CPU loading. Main CPU user is bdservicehost who uses us to 90% of CPU and 2 Gb of RAM. 3 computers with the same sympthoms. (and 7 ones still work normally for now).

Before yesterday every computers worked normally for at least 1 year with the same Windows 10, Bitdefender Total Security and cofiguration.

After uninstalling Bitdefender computer becomes to be useful.

I deeply checked these machines for viruses with alternative antiviruses program (DR Web CureIt! and Kaspersky Rescue Disk, both with alternative booting and actual virus bases). No viruses found.

I suppose that there is some problem with some version of Bitdefender Total Security. How can I get new version like 28.0... ? May be totalyy new version will not create brick from my machine(s)?

  • Hi Alex,

    I have done what you offered to do - fully removed current version and reinstalled from zero.

    Problem disappeared. Now everything OK.

    On the one hand it is good, the other I have no idea what did happen and why at several machines at once. I could only suppose it was "unhappy" bind of program build(s) and engine version.



  • Thanks for following up @AlexWhoHasAQuastions, glad to hear the situation was resolved 🙂
