rundll32.exe is running all the time (HJT log included)

[slvrstang]

I consider myself somewhat knowledgeable about computers and as far as I know, rundll32.exe should only be open when it's opening a .dll file.

I have run adaware and AVG to no avail.

I have also run HJT but I can't interpret the results, which is where I was hoping you guys could help me out.

What do you mean by "running"? It's always present in Task Manager.

Your HJT log is fine so far as I can tell. Makes a change.

[kylethedarkn]

Also, your HiJackThis log appears to be missing some entries, such as the Ro, R1, R2.. and several others. What I want to know is did you remove these yourself because of privacy issues(and if so please give the full log, you can cesor what you want private but dont remove the whole thing) or did those entries never show up in the first place?

[Suspishio]

.... and don't forget the running processes at the topof the CPU usage list.

[kylethedarkn]

.... and don't forget the running processes at the topof the CPU usage list.

Yeah and that too. :)

[slvrstang]

That is the full HJT log unless there are options I need to change.

Also, by "running" I mean is always present in task manager under my name and not under system.

This is a fairly fresh install of windows so maybe that is why the HJT log is short.

[kylethedarkn]

Ok do this then. Change the name of HiJackThis.exe to something random. It can be anything you want, but just change it and run hjt again. After you run the scan with hjt with a changed name post it here.

[jbennet]

Rename HijackThis to something else and run it again.

[kylethedarkn]

Rename HijackThis to something else and run it again.

lol I said it first. :P Look at my last post.

[slvrstang]

Renamed to HJT and ran

The bold line is what is bothering me.

Still looks like an imcomplete log, but lets try this now instead.

Please download Combofix.exe from here to your desktop. Double click it to run and and when prompted type 1 and enter. Now DO NOT touch the mouse or keyboard until the scan is done completely. It should finish shortly after it restarts the computer. After its done it will open up notepad, copy and paste the contents here in your next post.

post the combofix log in your next post.

Syl, your log is fine. Short, and that is nice - most folks ignore the instructions on running hijackthis and leave a bunch of apps running. My own log is short like yours, shorter, even.
Rundll will show all the time it is handling a process from a dll, the more threads it is handling the more memory it uses, but it should only ever use a percent or two of you CPU time, mostly in TM it should show zero time. And it will come up under your name if it is handling a dll launched by your profile.
I'd read your combofix log but you attach or whatever instead of pasting in plain text - it makes reading tedious..
See these two entries?
O4 - HKLM\..\Run: [NvCplDaemon] RUNDLL32.EXE C:\WINDOWS\system32\NvCpl.dll,NvStartup
O4 - HKLM\..\Run: [NvMediaCenter] RUNDLL32.EXE C:\WINDOWS\system32\NvMcTray.dll,NvTaskbarInit
-they are why Rundll is running all the time. Mine does not cos I don't have entries like that in my startup. I can observe rundll in TM by starting timedate.cpl from the taskbar clock.
