AddOns (sometimes called addons, add-ons, or mods) are collections of Lua/XML code that augment, modify, or replace World of Warcraft's default user interface. Addons vary greatly in scope and size — they may display information not presented at all by the default UI, add functionality to the default UI (e.g. additional buttons you can press to do things), modify the default UI's appearance (e.g. by changing colors or positions of UI elements) without changing its functionality, or even replace the default UI entirely.

I've isolated the issue to BanditUserInterface/BUI_MiniMap.lua lines 173, 174 within the function BUI.MiniMap.Show(). When Bandit sets up the minimap, it looks like this method makes a global call that effectively imposes itself over every other Addon including the Zygor guide. And if I'm not mistaken, the main map itself dubs as the mini-map, which may explain why it's constantly appearing.
I only subscribed about 2 days ago after coming back to WoW after 6 years. The game has changed so much since I left right around the Cata release. I decided to start fresh on a new server. I still had all my old links and logins to places like Curse, WowInterface, etc. Loaded up all the addons I had favorited years ago (of the maybe 1/3rd that were still maintained). Got to level 20 in a few hours of playing. Had to look a bunch of stuff up.
If you want to get rid of all of registries left on the program removal and don't want your Windows system is fill with redundant registries that someday may affect the system performance, you should perform a registry scan and clean with a sophisticated registry optimizer, it will help you clean all the useless and corrupted registry files on the system.
Because it's so much effort to click a button and go to a website? If you don't want to do that, then don't check out their addons. It clearly states in the title that it's from wow-pro. Just avoid them. I wouldn't have thought to go to their website to get an addon because I mostly just search on this site. So I'm glad that they posted even a partial addon and informed me that they have many more on their site. So, no, I won't support your moody, lazy demands of all or nothing. The purpose of addons is to make gameplay easier and more enjoyable. If their willing to invest their time into making amazing addons for the wow community, then you shouldn't bash them for advertising their site. Like Jason said, " If they do gain something from vists, they deserve it."
The part you need to understand too, is that the Zygor addon doesn't use an App like TSM to update many times per day your auction value. When i bought the gold guide i remember that i didn't understand much either, the results were random and from items i can't make much gold with. It just scans the auction house based on their most recent value update which can be days and days ago.
To make it easier to level professions to 800, most recipes will stay orange for 20 more points. This is a huge change! For example, the blacksmithing 780-800 part needed around 120 Demonsteel Bar and 60 Blood of Sargeras at minimum to craft 30 Waistguard. (you probably needed to craft 50 if you were unlucky). But now you will only need 20 Demonsteel Bar and 10 Blood of Sargeras to craft 5 of them.
Besides registry cleaner, it is also necessary to perform a defrag for your computer hard drive regularly, which is not only a good way to optimize your computer system's structure, but also can help you clean those fragments created in the incomplete program removal. There is a specific computer defrag utility available on the Windows operating system that enables the computer user to perform a defrag for the computer disk, or you can choose a free third party defrag tool like Auslogics Disk Defrag that opimize your computer disk in a quicker and more effective way.
