dllhost.exe proccess error

Question

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!

Hello Milad,

Welcome to Microsoft Community. The issue that you are facing with the computer might occur when there is a conflict between a third-party software or a driver. I would like to ask you a few questions in order to understand the issue better.

1. What is the model of your Asus notebook?
2. What were the results from the SFC scan?
3. Which anti-virus software are you using on this computer?

Method 1:

Try Safe Mode

Safe mode is the configuration of Windows, when it is running on only basic set of drivers and all the startups are disabled. To know more about safe mode, follow the article below:

http://windows.microsoft.com/en-us/windows/start-computer-safe-mode#start-computer-safe-mode=windows-7

If you are not getting dllhost.exe process message in safe mode, then perform clean boot.

Clean Boot

A clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update or when you run a program in Windows. To know more, follow the article below:

http://support.microsoft.com/kb/929135

Note: After troubleshooting, refer to this section ‘How to reset the computer to start normally after clean boot troubleshooting’.

Method 2: Run a Virus Scan

I would recommend you to run a complete virus scan using the Microsoft Safety Scanner. It will scan the computer for viruses and malicious programs. To download it and know more about it, click on the link below.

Disclaimer: Any data files that are infected may only be cleaned by deleting the file entirely, which means there is a potential for data loss.

Hope this information was helpful.
