A few times a day I have a message that pops onto my screen saying, "Cannot find 'file:///C:/Windows/dl.html'" When I click on OK (the only option), it connects to the internet. It is not only annoying but I am afraid it is some sort of virus - although I've done a complete virus scan with Norton's many times. Any suggestions would be appreciated.

It is likely this page is the result of a some type of "Spyware" on your system. On my home page, I have a section devoted to Spyware and several good (and free) removal tools. You can visit the site by Clicking here. On the top left of the page, click the "Spyware" link. I suggest you start by clicking the last link in the Spyware section and checking your browser for some common infections.

I hope you will find this helpful!
