dllhost.exe proccess appears after updating windows 7 ultimate

Hello

Two days ago,I updated My PC windows 7 (32 bit) Ultimate windows and after that whenever i click any file type, dllhost.exe proccess with below processid starts and even i close that, it will start again

C:\Windows\system32\DllHost.exe /Processid:{3EB3C877-1F16-487C-9050-104DBCD66683}

(before i update this windows, i didn't have this problem and i'm sure this dllhost.exe didn't infect by a malware! )

I searched for this and found These methods that didn't work for me:

1- rebuild icon cache
2-add dllhost.exe to data execution prevention list
3-run sfc /scannow command

This is a screenshot of dll and other files that this proccess handles

I have this problem in my Asus notebook with windows 7 ultimate (64 bit),too!!! (exactly after windows update several months ago....)

I searched for Processid:{3EB3C877-1F16-487C-9050-104DBCD66683} and it seems is wininet.dll

Please help me to solve this problem!

Please open an ELevated Command Prompt and run the following command,

REG QUERY HKEY_CLASSES_ROOT\CLSID\{3EB3C877-1F16-487C-9050-104DBCD66683}\LocalServer32

post the results.

Here are some instructions to make life easier :)
1) To open an Elevated Command Prompt Window (the ECP window), click on Start, All Programs, Accessories – then right-click on Command Prompt, and select Run as Administrator. Accept the UAC prompt.
2) To run the commands easier, highlight the block of commands, and right-click on the highlight – select Copy. In the CP Window, click on the black/white icon at top left – select Paste. The commands will run but may not complete the last command, so hit the Enter Key once.
3) To copy the results... click on the Black/White icon in the top left, and select Edit... 'Select All', and hit the Enter key - then use Ctrl+V or r-click+Paste to paste it into your response.

ERROR: The system was unable to find the specified registry key or value

Another thing-> After updating this windows,whenever i click a file to open it,some data will be written to below file and my try to delete this file cause this error->this file is open in com surrogate!

C:\Users\Milad\AppData\Local\Microsoft\Windows\WebCache\WebCacheV01.dat

That doesn't surprise me too much - despite the fact that it was posted by an MS staffer as a potential diagnostic aid

Having said that, a search of my registry may give a few pointer to your problem, so...
Please open an Elevated Command Prompt, and run the following commands..

REG QUERY HKCR\CLSID\{0358b920-0ac7-461f-98f4-58e32cd89148} /S
REG QUERY HKCR\AppID\{3eb3c877-1f16-487c-9050-104dbcd66683} /S
REG QUERY HKCR\Wow6432Node\CLSID\{0358b920-0ac7-461f-98f4-58e32cd89148}
REG QUERY HKCR\Wow6432Node\AppID\{3eb3c877-1f16-487c-9050-104dbcd66683}


Post the results.

That looks like it may be the cause - there are no SysWOW64 entries present... (This is a 64-bit machine?)

I'll work up a fix protocol later - but this may be the tip of an iceberg... Have you been using any form of registry 'cleaner'??

thank you so much for your quick replies!

All of those screenshots are from my PC system with windows 7 ultimate 32 bit architecture
But as i said before have this problem in my notebook with windows 7 ultimate and 64 bit architecture,too...is it necessary to take screenshots of the cmd commands in my notebook windows and put them here?

Yes,i use tune up utilities (AVG PC tune up) in both systems (PC & notebook)!!
