Multiple Dllhost.exe*32 COM Surrogate

Recommended Posts

Please help.  For last several days when I start Windows 7, performance very sluggish.  When I look in task manager, I see multiple instances of dllhost.exe*32  description COM Surrogate.   These take up all of the memory.  From other searches, it sounds like this may be malware/virus.  I ran a Farbar recovery scan search and have attached the resulting txt files.  Any help you can offer is appreciated.

Thank you very much for your help.  I am in the process of running the fixlist step.  Just to confirm, about how long should this step take?  The Farbar Recovery Scan Tool has been on the "Fixing is in Progress.  Please wait..." step for about a half hour so far.


Best regards,

We need to clean up first:


Download "Delfix by Xplode" and save it to your desktop.


Or use the following if first link is down:


"Delfix link mirror"


Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator


Make Sure the following items are checked:


    Activate UAC
    Remove disinfection tools
    Create registry backup
    Purge System Restore
    Reset system settings


Now click on "Run" and wait patiently until the tool has completed.


The tool will create a log when it has completed. We don't need you to post this.


Part of the routine will be to create a registry back up with ERUNT,  the back up will be created here:




When all is known to be well with your system you can delete that back up folder if you consider it as not needed...

Any remnant files/logs from tools we have used can be deleted…




Read the following link to fully understand PC security and best practices, you may find it useful....




Let me know if we are ok to close out...


Thank you,
