If you have the VirusBarrier X6 Anti-Spyware feature enabled, you may see alerts about KSURL or KSFETCH.
KSURL and KSFETCH are used by Google Applications such as 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.
Since ksurl 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 at this time.
