I'm going to preface this post with saying that I'm a huge newb when it comes to computers... so please respond in the lowest technical level you are able to. Thanks ahead of time!
I installed the client a couple weeks ago and I was having a blast. A couple days ago I noticed my chat windows settings kept on changing without any action from myself. IE: Not being in LFG, not being in guild chat. Also, I couldn't shift click player's names and get level/class/zone info for them. The former wasn't a problem because I could just rejoin those channels but I had no Idea how to fix the latter. Not my biggest problem.
Last night I was questing and noticed all my key bindings were reset (they reset mid session, they had been there for the past 2 hours) so I reset them. Thought it was curious but went on questing. About 10 minutes later I was flying so I clicked on the Atlas Loot mod to see loot tables in ST but it was stuck on the ZF map. I closed out and did /reloadui because that is usually what I do to fix any issues I have. After the reload, all my addons stopped working. I logged and looked at the addon interface and they were still there. Load back in, nothing. Switch to an alt, nothing. This is when I just close WoW and tried to reload. I was met with an error code. I looked at the client folder and it looked a little thin and then noticed my recycling bin was full of files. All of which involved my WoW files.
Can anyone help me understand what is happening. I don't want to set everything back up and have this issue again.
Points of interest:
-New laptop (purchased about a month ago). It has malware protection.
-All WoW Files were located in the documents folder
-Addons: All the addons I got from the forum links (GitHub). They include: Atlas Loot and Enhanced, A UI mod (I can't remember the name), SUUCbag, Questie, A U X, Mail and I think that's about it.
-Only my wife and I use the computer. The only thing I have loaded on it was the WoW client and addons. She only uses it to do online purchases and bill payments.
-No gold purchases
-I didn't give my login / account info to anyone
