task killer 2.30 still good ?

is this program still any good.i pickup that website called fbi cber crime division somtimes . whe i right click on task killer icon in task bar and tap on the windows. theres usally 4 or 5 iexplorers running. .to get rid of this i have to delet one at a time before that page goes away. when i do hit the right one the other pages i have up and runnining close out. my question is .is there a another program that shows the name of this specific site so i can delete just that site.ran malwarebytes full scan it found nothing.computer runs just fine otherwise.

I use the built in task manager. Right click on the bottom task bar and then go to process to see and/or stop what is running.
Process explorer gives more detail and just as good, but a bit different, from what you asked for.
Process Explorer

thanks for your answer . i'm aware of process explorer. it's to complicated for me.i'll be closing this post now.
