Are the antivirus companies working with the hackers?

I bought my Norton Antivirus software about a year ago from today, and now I’m getting a message that my subscription has expired and need to be renewed. I thought antivirus software was forever after you buy it, and all you have to do is to keep it updated. I know you probably think like me, ‘The Antivirus company must be working with the hackers to stay in business why got so much security treats.’ It just seems like every time I turn my computer on and get on the internet, there is a new treat, so I got to update. What’s up with that? I never really check out the subscription notice, because I know there is a possibility that I might have to come out my pockets. But what can we do, viruses are real and we need protection from them, regardless of what we think. My uncle was having problem logging in to his online account, so he called his ISP and was told that he changed the password a few days ago and that he had order some equipments, which he knew he didn’t. To make along story short, he had a virus (Trojan horse) on his computer that was sending information back to the hacker. He probably got it from a file he downloaded, so I guess I better get my subscription updated.
