Inactive Passshow Removed. Suspicious?

[Inactive] Passshow Removed. Suspicious?

So, I had found out the pop-ups I had been getting on Firefox, and the lag on it, had been coming from Passshow. I discovered it when I was going to uninstall Ad-block, as that was the only add-on I had willingly installed.

So, I go to Uninstall/Change Programs in the Control Panel. I find Passshow in there, and I uninstall it.

And I'm not a computer newb, so I was a bit wary on the fact the word "uninstall" on the window title for uninstalling was lower case. Not uppercase. Odd...

I was wary, as I know there can be custom uninstallers for browsed hijackers, like Conduit, for example. The custom uninstaller for Conduit uninstalls itself, but also takes your computer with it. So, that's why I was wary.

I managed to fix my Firefox, and delete a suspicious looking profile, and started fresh. (I imported Firefox bookmarks to Chrome.)

After uninstalling, I saw a noticeable stall between doing actions, but I find out it was just an emulator I downloaded. Not a big deal. I just deleted it.

But, the thing is...

I go to Mouse options, and I click on the 'Pointers' tab, and I get these errors saying that things in C:\Windows\resources\Themes\Royale Remixed\Cursors are missing. Does this have something to do with uninstalling Passshow? Probably so, as this had never happened before today.

So, I decide to search up the folder.

It turns out, I have no folder called "Royale Remixed ". A folder had been removed? It looks like this is the case.

I'm very confident that this had to have been from uninstalling Passshow.

Can someone tell me what is really going on?

EDIT: I come to find Royale Remixed is a theme. After uninstalling Passshow, I saw no difference in how my computer looked. Passshow must have installed something. I'm still looking for answers.

EDIT 2: When trying to post a comment on deviantART, I get an error saying "Uncaught Exception. "
