Netgear Armor Nearly Useless?

I generally find most security apps to be nearly useless for most users, even very technical users like myself. When they do provide a warning, there is usually nothing one can do about it or there is rarely enough information provided to make an informed decision. Netgear Armor seems to be no exception to this.

1. Most of the sites it has blocked appear to be fine and sites I want to go to. Is there any way to control what sites it blocks? In other words, can I have my own white list?
2. A recurring message I'm getting about my printer is nearly useless. It's something like this: "The printer [brother] has a low security ftp login ID or password". Notice the use of the "or" in this warning message? This means it could be the login ID "or" the password. Why not tell me exactly? They are very different things. Furthermore, this printer doesn't even have ftp setup.
3. Lastly, either Netgear Armor or Bitdefender (probably Armor) is pinging my printer every single week and as a result, making the printer print out 3 pages of mostly blank space with some garbled text. Very annoying. I would rather not waste paper like this and don't want the printer to suddenly come alive to print these 3 sheets, sometimes in the middle of the night. Does anyone know how to exclude a device on your network from being scanned or perhaps to manually mark it as safe?

My trial ends in a couple of days and I'm inclined at this point to uninstall Armor from my router and Bitdefender from my computers.

Thanks.
