It's the first time I post here, and I took a look at the Welcome Guide and some sticky posts about what one should as first time users.
I also search this forums about the problem I seek to solve.
I'm a bit conscious about what's going on on my PC when it's running, so I usually take a look a task manager to check if there is anything "abnormal".
Recently I found this dllhost.exe running (I'm on XP Home, SP3) which I haven't seen before, and tried to discover what is it, and what it is doing.
Let's put it simple:
I usualy have about 34 processes running.
I don't feel any performance hit when running the machine.
I checked my 7 svchost.exe's running and they all seem "harmless".
This dllhost.exe always run at system start and never stops, unless I stop DCOM process first.
This is not a problem with the process itself, as dllhost.exe seem to be where is meant to be (..\Windows\System32\).
The problem is what is dllhost.exe doing, and what makes it running on windows startup.
I found no related sartup calls on the registry.
I found there is a file named DLLHOST.EXE-5353C76C.pf, located on ..\Windows\Prefetch\, and this is the one that keeps dllhost.exe running.
I try to delete DLLHOST.EXE-5353C76C.pf, and it comes back to life again.
Of course I'm sure this ins't a good thing, and as I searched the internet, I found this might be virus related, but I couldn't solve it.
I have mysystem updated, and I have MS Securty Essentials running.
Now, can anyone please help me to sort the problem out.
I'd be appreciated, thanks.
