IE8 and ccSvcHst.exe

Hi, I downloaded Internet Explorer 8 yesterday and installed it without any problem (XP SP3 and NIS 2009 16.5.0.135).

 

When I open Internet Explorer 8, it shows up two processes in my task manager and when I close it, they disappear; but if I open IE8, select offline mode, close it and clear all the elements in history, when I reopen IE8 those two processes remain in memory and don't disappear anymore (and if I try to close XP or restart it, there is a conflict with ccSvcHst.exe).

 

Anyone else with this problem?
