Windows 7: Multiple instances of dllhost.exe*32 Com Surrogate killing memory

Windows 7 64 bit Premium Home Edition
Multiple instances of dllhost.exe*32 Com Surrogate killing memory

I am running Windows 7 64 bit premium home edition, 1.34TB HD and 8 GB Memory, IE 11 which I just installed. The last couple of days I've noticed my performance slowing to a crawl. My IE passwords and user names no longer load, Icons in my folders no longer load, the Progress Bar in each folder is continually loading each time I open a folder. I opened Task Manager and found multiple instances of dllhost.exe*32 running, and some with a Memory usage over 200,00k.

I've run TDSSKiller, RKill, Malwarebytes, Hitman, Rogue Killer and Emission in that order to make sure it wasn't a Trojan masking itself as a valid dll, no effect. Reading through the forums I see where a corrupt movie file or extension can cause this. I wanted to do a Restore to an earlier point, but the earliest I can go to is yesterday, and that's when I first started troubleshooting. Last week I loaded Windows Live Movie Maker. I was unable to do an uninstall as there was no uninstall command. I've ran every movie file that I can find in an attempt to isolate it to delete it - no luck. If anyone has any suggestions I would appreciate it. I'm no PC expert, in fact I probably know just enough to be dangerous, so keep that in mind when replying.

One other thing that came to mind after I posted is if I set all my folders to use Icons only, no thumbnails, the problem goes away.

Check in the folder options from control panel, look in the view tab, uncheck box for Launch folder windows in a separate process... then reboot.

Thank you for the reply. I did, and no joy. Same symptom. Thanks for the suggestion just the same.

Check this link*32 I had this occur, MSE stopped most of it when it happened, got a pop up notice, but still had multiple instances of dllhost.exe *32 in Task Manager processes . I have an AMD temperature application on my desktop shows CPU and MB temps and fans speeds. CPU temp is usually in the low 30 C range, it was jumping to mid 40 C constantly, I would end the 10 or 15 instances of it and things would calm down for a short time but soon there'd be two dozen instances of dllhost.exe *32 running.

Ran Super Anti Spyware and Adwcleaner to remove it. Per the Google link it could have been much more serious than it turned out to be, I have to think it was MSE real time protection that prevented it from being a worse case scenario.

You might want to take advantage of the security forum here and post there. Some very knowledgeable people that can help.
