Jinxed

I think that I just jinxed myself. Is there any way that my computer or the company that I use for my broadband access can see what I am doing on the internet? I recently got a tip that I could change providers and get my current service for a fraction of the price. When I went on line to find out about some comparable companies then my internet service just slowed down relative to dial up connection speed. Did I just jinx myself by thinking I could get a better deal then what I am currently getting? I like the service, I just do not like the fees.
