Did you just run into a download or a file on your computer that has a digital signature from CommonShare? Some of the security products refers to the detected files as Adware.SwiftBrowse.CH and Gen:Variant.Adware.SwiftBrowse.1. The detection rate for the CommonShare files collected here is 30%. Please read on for more details.
You will probably see CommonShare when running the file. The publisher name is displayed as the "Verified publisher" in the UAC dialog as the screencap shows:
You can view additional details from the CommonShare certificate with the following steps:

Here is a screenshot of a file that has been signed by CommonShare:
As you can see in the screenshot above, Windows reports that "This digital signature is OK". This means that the file has been published by CommonShare and that the file has not been tampered with.
