The issue is a bit strange, but this is the best I can describe it:
I am currently using Windows Vista, and running the most current version of Chrome as my browser. I also use AVG anti-virus and Rootkit killer.
Recently, my browser will randomly ask me to "Save as" when I go to a new webpage or open a new tab. This is always preceeded by Chrome telling me a pop-up has been blocked. So apparently the pop-up is stoped, but in its death throes it gets to ask me to save the webpage I'm going to.
This will happen no matter what the webpage is, so I know the pop up isn't comming from the pages themselves.
