I hope this the right place to post this.

There is incompatibility issue on Spybot Anti-Beacon and Revo Uninstaller, when uninstalling a program using revo uninstaller while all the protection of the Anti-beacon is enable, the Revo Uninstaller can't do its thing.

So what I did is, I disable all the protection of the Anti-Beacon before using the Revo Uninstaller.
