My laptop seems to be running slow and I was trying to work out what's wrong with it. I read somewhere that the rundll.exe processes could be concealing a virus and I followed instructions to check them out.
I have Windows 7 and in the task manager it lists the processes but does not show any other details, including the command line (which I made visible). If I click "open file location" nothing happens, same if I click "properties". The 3 processes are 232, 632 and 792K.
However, it says online that you are legitimately supposed to have rundll running, but I only have the 3 listed above in the task manager. There is an application called rundll in the system 32 folder.
Can someone please tell me if these processes are legitimate?
