could I be infected???

Today I was backing out of a webpage and a windows meddage popped up and said something like this-

 

Are you sure you want to navigate away from this page, I think I found some really great offers you might be interested in. I clicked x and was able to leave the page?

 

 The webpage seemed fine. Anyway it wasnt a regular poppup- It was like a windows popup. Could it be a virus or something???

 

I have malware bytes, nis 09 and superantispyware
