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.

Hello
Many updates installed (I means that updates installed several days ago not old updates) and it's not clear which one caused this problem:

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}

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'??
