Large number of COM Surrogate processes using up memory

Question

Memory is spiking on my Windows 2019 server. There are over 2,000 COM Surrogate processes. Right-click and properties shows dllhost.exe in the system32 folder so I think that indicates they are legitimate, ie not malware. We have several other vms from the same source which are not having this problem. Any ideas?

Hello,

Thank you for posting in Q&A forum.

First, performing a clean boot allows you to start your PC with only the necessary services, ruling out third-party software.

Next, run sfc /scannow to repair corrupted system files.

High memory usage can also be related to disk problems, you need to run the CHKDSK command and try to repair any corrupted sectors.

Then, download the software "Process Monitor": Process Monitor - Sysinternals | Microsoft Learn

Launch Process Monitor: There you will find the file that dllhost.exe tries to access over and over again.

Once you have found the file, delete it from your computer
