Change NIS 2006 to NIS 2011 with current sub, ramnit!inf problems still

I renewed my sub for NIS 2006 more recently and someone called "floplot" told me I could change my sub to NIS 2011 as long as my PC met the requirement for free!  Anyone know how I would do that, or is it a myth?

 

I cannot get rid of this ramnit!inf worm, its been like this for weeks!  I thought I got rid of it, and Quads told me what to do, so I must have done something wrong.
