Dllhost.exe in /C:/WINDOWS/ServicePackFiles/i386

  1. My laptop bluescreened the other day twice when I attempted to start it up. On the third try, it worked, but it's been acting strange. I open a window and it freezes for about a minute, then works normally, then freezes for another minute and so on. Now today, I tried to watch a movie on Netflix and I got an error message saying it had to close in an unusual way. It said dllhost.exe somewhere on it, so I googled it and found that viruses can disguise themselves as dllhost and that the only place it should be is in the system32 folder. So I searched my files for dllhost.exe and it had three files in Prefetch, one in system32 and one in ServicePackFiles/i386. I scanned it with Malwarebytes and Avira and both showed up clean. I absolutely have no idea what I'm doing or if it's related to the bluescreening or not, but I'm hoping I don't have a virus.

    Welcome to TechSpot! Dllhost.exe can be a normal process of the OS, or it can be malware.
    If is becomes an Infected copy, it could be restored from the ServicePackFiles\i386
    And Prefetch is another normal location.

    The only way we can determine if you have malware is to start with the following:

    Please follow the steps in the Preliminary Virus and Malware Removal thread HERE.
