Is this a good campaign or not so good for a beginner



Not really, not enough offers to test against. I would not suggest going into an area against giants with huge ad spend. (Norton, etc.)

By no means and I suggesting to follow the crowd, but pick a vertical you can scale and test multiple offers. Anti-spyware is limited unless you are working with maybe CJ.
 
you would have to have deep pockets to compete in the antispyware world i'm afraid. If you have your own antispyware software then you might get some traction that way on some of the free download websites
 
AntiVirus is a very high volume niche, and due to the fact that the consumer usually requires an immediate fix, the conversons are high. If you are looking to promote software, and want a niche that can be scaled to high $$$ a day then it's a great place to start.

If you're just getting your feet wet with paid traffic then it can definitely get pricey, but depending on the offer, and how much support your network is willing to give, you can see success out of the gate.

What kind of traffic are planning to work with? Paid or Organic to start?
 
I think it should not be a good choice at the beginning. Although you can target it later, not at the first.
