When I start a program such as ventrilo or partypoker and sometimes internet explorer, they stop working and the "not responding" message comes up.  If I do ctrl + alt + del to end the process, it doesn't work.  Sometimes my computer just freezes.  I'm not sure if this is a virus but I haven't changed any settings on my computer and I am the only one that uses it.  Is partypoker safe or should i delete it seeing as I downloaded it recently and my problems have started just recently as well.  Thank you.
