Hi, I have noticed the presence of this process among the processes in the
task manager, early from the start up of windows. I am pretty sure that few
days before that process was not ALWAYS present. What do you think about?
That process doesn't normally start with Windows and can indicate
malware, but since I don't know anything about your computer and what
programs/processes you have running I can't say for sure. It could be in
use by something legitimate.
The normal general troubleshooting steps are:
The First Question Of Troubleshooting: what changed between the time
things worked and the time they didn't [the time rundll32.exe wasn't
showing up in Startup and the time it started]?
The Second Question of Windows Troubleshooting: what is the
malware/virus status of the machine? If you think it is clean, what
programs (and versions) did you use to determine this?
Be sure the computer is clean:

And then if you find the computer to be completely virus/malware-free
and you still have the process running, do some clean-boot
troubleshooting to narrow it down:

You can also run Process Explorer to see what is using rundll32.exe.
