Deleting this file is essential if you see it running after you open Internet Explorer.

I have SBC/Yahoo DSL which includes a large collection of files and programs
All I know is that my computer starts running at 100%CPU from this thing. I end the process and everything is fine and I am still on yahoo with no interruptions which makes me wonder if it really is yahoo. If it was, wouldn't it close the window?
You will find that yahoo VERY often hides its applications, such as this one so that users cannot uninstall them, that alone tells me that Yahoo products are spyware.
