Did you just stumble upon a download or a file on your computer that is digitally signed by crimsolite? Some of the security products refers to the detected files as Adware.SwiftBrowse.CH and Adware.NetFilter.E. The detection rate for the crimsolite files collected here is 38%. Please read on for more details.
You will typically see crimsolite when clicking to run the file. The publisher name is then displayed as the "Verified publisher" in the UAC dialog as the screenshot shows:
You can also view the crimsolite certificate with the following steps:
- Open up Windows Explorer and locate the crimsolite file
- Right-click on the file and select Properties
- Click the Digital Signatures tab
- Click on the View Certificate button
Here's a screenshot of a file digitally signed by crimsolite:
As you can see in the screenshot above, Windows states that "This digital signature is OK". This means that the file has been published by crimsolite and that the file has not been tampered with.
