McAfee Anti-virus alert


I just installed the newest version of pdfforge and was told by my anti-virus program that a potentially hostile program was being installed on my computer.

The details are:-

Detection Name: Widgi Toolbar (Potentially Unwanted Program)

File:C:\\(x9)\\pdfforge Toolbar\\IE\\1.1.2\\pdfforgeToolbar.dll

What gives with this? How comes McAfee tells me you I am installing a potentially unwanted program?

I wanted you to know this fact so you can negotiate with McAfee if it's confused.
