If you purchased the NIS 05 and you did not pay a new subscription in 2006, then it is expired.
You would have to purchase a new subscription for 2009 for 2010. Not a renewal. I would find that out, since NIS05 is not working.

SPEAKING WITH MY EXPERIENCE TRY SOMETHING ELSE. If you find the information below helpful, pls rate me.

FREE SPYWARE
Download Spybot Search & Destroy. Restart computer, then run Spybot to see what spyware comes up, AND DELET IT.

FYI---Virus Protection-- 2 programs of virus protection will conflict with each other and will actually cancel out the protection. SO just download one.

Running Spybot Search & Destroy with EITHER Avast or Avg (great Free virus protection programs ) will keep a computer in good working condition. FREE
