Error while unpacking program, code 2. Please report to author.

Yes I realize this has been posted before but I could not respond in those old threads, so here I am. 

We have had Norton for years but this only began popping up in the last few days. No matter what I do, I cannot get rid of it and I am tired of looking at it. 

Please help and I will give you a "Kudos". And then we can move on to the possibility we have a worm in our entire home system that wasn't detected by Norton. 

I see in previous threads that system information was requested. Please let me know if I have forgotten something helpful.
