Rundll32.exe should not be run?

Recently, I noticed that two rundll32.exe process running, how to time its has been actually done that, I don't know.  A process uses somewhere about 1 600 K of memory at the present time, the other is using 3 100 K.  However, whenever I get on a game or something one of them sometimes get swept over 150 000 K memory.  Is this normal, or should I terminate a process?

You can download and use Process Explorer to see exactly what is taking your time processor/CPU and memory. This can help you to identify applications that you might want to consider alternatives for and get rid of all together.

Every time I tried, would open a window saying "Choose the program you want to use to open this file." If I try to download a new virus scanner, it says the same thing.
