Solution I. Re-enable downloads in Internet Explorer

  • Close all Internet Explorer windows.
  • Press the Windows key windows_key_icon.jpg + R
  • Type inetcpl.cpl into the Open field and click OK. This will open Internet Properties (otherwise known as Internet Options).

How many is "several"? It's not all that unusual to have more than one instance of dllhost.exe running, and it can cause high CPU usage -- just make sure the dllhost instances that are running are located in the C:\Windows\system32 folder. Right click each instance in Task Manager>Processes, and select Properties, General tab. If the process running is located in the system32 folder, it's probably safe. If it's located somewhere else, then it's malware.

 

dllhost is like svchost.exe. It's a system file that serves as a host for other dll files and binary executable files. In cases where it's causing high CPU usage not caused by malware, another dll file being run through the host process is usually the culprit.

I would recommend making sure it's a malware problem first. We really don't have enough information to determine whether that's the case or not.

 

How often does this problem of multiple dllhost processes using up excessive CPU occur? Does it only happen when certain programs are running, or randomly? And, again, how may instances of dllhost are we talking about?

Here are known versions of dllhost.exe

 

http://www.systemlookup.com/search.php?type=filename&client=malwaresearch-ff&search=Dllhost.exe

 

The probability of malware is extremely high.

 

I recommend the OP starts a malware removal thread.

Looking at the  link supplied by TsVk!, the probability that this is malware is about 80%.

 

I am sending the OP a PM to open a topic in the 'Am I infected?' section and locking this topic.

Chris Cosgrove locked this topic. Please do not use the report function as a way to comment here since you are not able to reply to a locked topic. Those who can help you will not see the report.

Instead, do as suggested by Chris Cosgrove and start a new topic in Am I Infected.

One of your reports stated "The dllhost issue seems to be gone only one running now. But have 15 SVCHOST.exe running not sure what that means".

You do need to make sure that there is no malware on your system.
