Serious help needed Unknown virus

The past couple days have sucke....  first off I got a virus from a .zip file "live internet security platinum" which I got rid of with some scans. Right after deleting this a new virus appeared redirecting me to random websites such as click.get-answers-fast.com and Consumerlifestyles.com. At this point I will take any help i can get I bought norton internet security 2012 which did nothing at all malwarebtyes gives me a message saying it's successfully blocked a potentially malicious website adaware again did nothing and even NPE(Norton Power Eraser) when ever i try to copy my logs from NPE my computer crashes so I will just give you the virus's name? I don't know but here it is

 

\REGISTRY\MACHINE\SOFTWARE\Clients\StartMenuInternet\IEXPLORE.EXE\shell\open\command\""

 

NPE won't delete it for some reason I'm guessing this is the source of my problem but I'm not a big computer person. So thanks for reading this and thanks for the help.
