Did you just find a download or a file on your computer that has a digital signature from webget? Some of the security products refers to the detected files as Adware.SwiftBrowse.AD and Adware.SwiftBrowse.L. The detection rate for the webget files collected here is 24%. Please read on for more details.

You will probably notice webget when double-clicking to run the file. The publisher name shows up as the "Verified publisher" in the UAC dialog as the screengrab shows:
