If you have BCK9 and are tired of it, here's a solution.

First, go to Services (control panel). Find Blue Coat and stop it.

Go to C>Program Files and Copy the Blue Coat folder. Paste it to my documents and .rar it. (delete the one in Program files)

Third step, go to C>Windows>System32>drivers and find bkcd, CUT it to my documents, and .rar it. (delete leftovers)

After that, restart your PC, DONE.
