Top site are redirecting on google?

I dont know how this can happen but it is. Can someone explain.

I searched for "iphone 3gs skins" then I clicked on my site
www.iphone3gsskins.net
which is like #4 and I was redirected to some other crap site selling cheap asian market stuff.

Now this does not happen every time you click. But if you reload and click again it does it.

I also clicked on other sites as well and the same thing happened.

How can this be possible? Does google know about it?

 

If its true, then it's a cloak page.

 

You site is cloaked or redirected or may be hacked

 

is there any benefit of such redirecting

 

It did it just now

here is the link it redirected to. It changes though.

here is a screenshot

So what do I do to fix this?
I just put the site up last week.

 

Ok now I am getting these same site redirects when I search for site cloaking.
Does this mean it is my brower that is infected?

I use google toolbar

 

Try out with mozilla firefox3. It is more safe and secure.
