rundll32.exe error?

everything was ok from the last three months
one day when i was on the internet for about 2 hours
suddenly something happened from the internet
my browser MSIE8.0 stopped responding my computer slowed and started reading harddisk continuously
avast4.8 home new updated reported nothing
when i shutdown the computer it gave error rundll32.exe not responding
when i started the computer everything was ok
but when i started MSIE8.0 the same problem took over everything
i reinstalled my browser and everything is fine
i used regcure to remove dll errors
i optimized my computer using Window Power tools - optimized dll handling
everthing is fine till today but still sometimes when i shutdown windows xp sp3 (Updated regularly with windows update) it shows rundll32.exe closing window not the not responding message came again on shutdown.
i dont know why the rundll32.exe window is coming sometimes.
is my computer is infected with the viruses and malwares
