If it’s just a folder in Windows Explorer opening when you log in, that’s not a program, so you’re not going to find it in the Control Panel. It’s not something that was installed, so there’s nothing to uninstall.
But this is interesting. Let’s talk about what it might be and what you can do to fix it.
Could it be malware?
This sounds very similar to automatic start entries left behind by malware that was incompletely removed (which seems unlikely in this case) or a program that was removed without cleaning up after itself properly.
Unfortunately, I can’t say definitively that’s what’s going on here. The folder doesn’t really have an unusual path, but I can’t say for sure. For now, let’s assume that this is completely benign, so we can explore the other ways that this can happen.
It’s possible that that you accidentally put a shortcut in the wrong place in your Start menu. Place something in the Start -> All Programs -> Startup folder, and every time you log in that shortcut will try to execute. If the file is removed, but the shortcut is still there, a folder may automatically open.
Fortunately, there are fairly easy ways to remove this.
Start by using a tool called Autoruns. This is a free download from Microsoft. Because it’s kind of techie to use, check out my article called, “How do I remove this error on startup after a virus removal?” This walks you through the process of searching for and removing the autostart entry that causes this folder to appear when you log in.
Never mind that the article is about malware. While I can’t be 100% positive, I don’t believe you have malware. But the process that fixes leftovers from malware is the same one that we’ll use to fix the problem that you’re seeing here.
In your case, you’ll search for “Amazon.” In fact, I suggest that you also search for the “Application Data” part of that folder path as well.
It’s important that you look for that specific path; what you see in Autoruns needs to match the path that you’re seeing on startup. That way, you don’t accidentally remove the wrong thing.
For example, if the item that’s opening is “C:\Users\LeoN\AppData\Roaming\program\foldername” and you search for “foldername,” you may find several instances in Autoruns. You would definitely NOT want to remove something like “C:\Windows\System32\program\foldername” by mistake. That’s why it’s important that what you see in Autoruns matches what you see on startup.
You might have other legitimate entries that include “Amazon” in your startup folder or elsewhere in autoruns; you don’t want to mess those up. But you do want to look for the one that matches this pop-up folder that shows up when you login and then simply disable or remove it using Autoruns.
Hopefully, this is a simple process and will work for you.
