Did you just run into a download or a file on your computer that has a digital signature from PlurPush? Some of the security products refers to the detected files as MalSign.Generic.42D and Adware.Agent.OBN. The detection rate for the PlurPush files collected here is 11%. Please read on for more details.
You will typically see PlurPush when clicking to run the file. The publisher name is displayed as the "Verified publisher" in the UAC dialog as the screenshot shows:
You can also view the PlurPush certificate with the following steps:

Here's a screencap of a file digitally signed by PlurPush:
As you can see in the screencap above, Windows states that "This digital signature is OK". This means that the file has been published by PlurPush and that the file has not been tampered with.
