This is correct, this is how It's supposed to be and the reason why nothing would load is because you would have to reinstall smapi since its probably freaking out because it can't locate your mod folder in the content folder. Since you moved the mod folder you would have to reinstall smapi to update the location of your mod folder.
Also I would invest into downloading
STARDROP, it's a mod manager for stardew. It will tell you what miss requirements there are, when a mod needs updated. It's pretty handy. But it's not a mod so don't install it like that. It's installed like a regular .exe.
Also I work in I.T, avast is pretty universally hated between us. It's okay but its extremely hard to fully get rid of. Just because you uninstall it doesn't mean it's fully gone. Having two antivirus activated can really mess up your pc so when you go into file explorer it will open to your home page, in the top right there will be a search bar that says 'Search Home' type in Avast and if anything comes up, delete it. And in regard to aura, I have never heard of it.
A little pro tip from me, Windows Defender works just fine and if you really want antivirus
Malwarebytes,
Norton, or
Bitdefender would be your best bets. Also get yourself a non chromium web browser like,
Firefox and then download
uBlock Origin, you'll never have to worry about viruses again.
(chromium web browsers are developed by Google and made available under open source license. Most browsers buy this license and build on the code like Google Chrome, Opera, Edge, etc etc. Basically, Google is the core of the web browser you're using and unless the company is changing specific things about their coding its basically just Google Chrome with different aesthetics. Non chromium web browsers are coding that was built from the bottom up. They don't use Googles coding. ((Plus Google Chrome is known to be a RAM eater, so its known to slow down your pc)))
