If you have NetBarrier X8 installed, you may see alerts about KSURL or KSFETCH.
KSURL and KSFETCH are used by Google Applications such as Google Chrome.
For example, Google Chrome Helper is downloaded to a new directory every time there is an update, and the rules must be reset for the "new" application.
If NetBarrier is set to alert you when an Application or Process is accessing the Internet you may see requests for KSFETCH or KSURL. You will see these multiple times only if you have more than one Google Application installed. Once you have Allowed or Blocked each instance of KSFETCH or KSURL, you will no longer see the alerts.
Since KSURL or KSFETCH is deleted and then redownloaded, VirusBarrier X6 considers it a new application. There is not a way to create and keep permanent rules for these applications in VirusBarrier X6.
