While looking at my blog on my sister's computer, she asked me why I had links in my posts to things like tennis shoes and wedding cakes and sweet dreams. I told her that I didn't make those links and I then looked more closely at the way my blog appeared on her computer screen. The links that I put in the posts are only highlighted while the Adware/Spyware links are highlighted and double underlined.
I don't think there is anything I can do from my end to prevent this. I wanted to let everyone know that if my blog shows up with strange links that lead you to sites that are trying to sell you something, I had nothing to do with it and you need to check your computer for Adware/Spyware.
