I was wondering what the process for deleting a infected DLLhost.exe file. My virus software doesn't detect a virus but I read that if your dllhost.exe exceed 5-6 KB than it is infected. I am unable to delete it gives this following error: "Require permission from TrustedInstaller". I need to do the same for svchost.exe file.
You're confusing svchost with dllhost, they're not the same.
Size of Windows 7 64bit version dllhost.exe located in \Windows\System32 folder is 9.728 bytes
Size of 32bit version located in \Windows\SysWOW64 (or \Windows\System32 if you're using 32bit Windows) folder is 7.168 bytes
If you've got a different value then do as zhihao50 said and reinstall Windows.
The file svchost on my computer is of 27kB size and dllhost is 9.5kB. I'm using Windows security essentials antivirus, it haven't detected any virus.
Moreover my main problem is my windows photo viewer crashes frequently, while browsing 10-15 photos in photo viewer with right arrow key it crashes and shows me error below. Do you think it is because of size of svchost or virus, I have tried almost all the methods in the internet to find the solution but has been unsuccessful. Plz help..
