Conficker and vobfus at the same time

[lights0123]

I was just working on my computer when my AV (Avira) popped up with:

F:\cbteor.exe
[DETECTION] Contains recognition pattern of the WORM/Vobfus.F worm
Begin scan in 'F:\cbteor.scr'
F:\cbteor.scr
[DETECTION] Contains recognition pattern of the WORM/Vobfus.F worm

I investigated it, and I noticed those two files. I checked for other instances of it, but I didn't find anything. Also, I noticed that the autorun.inf in there was 57KB, but didn't really notice it. 15 seconds later, my AV popped up with:

F:\autorun.inf
[DETECTION] Contains recognition pattern of the WORM/Conficker.Autorun.Gen worm

I opened up autorun.inf, and there was a lot of random binary. I read this page. I was thinking that I had something like it, until I realized that it said

Open=RUNDLL32.EXE .\RECYCLER\jwgvsq.vmx

I had that same file, except for in RECYCLER, I had a folder with some random numbers, and then jwgvsq.vmx. I use Windows 8.1 and the only things I've installed recently are hfsexplorer and MiniTool Partition Wizard. Here's what I'm wondering:

• 
  ■ Why is this happening only in my flash drive?
  ■ Why is Conficker appearing in 2015?

Depends. What else was the flash drive plugged into?? Besides your PC?

Looks like thats how both of them spread. On removable disks.

I left my flash drive for 1 week in my computer while I was away. When I came back, that appeared. Other than that, there was no other removable media, and no one used my flash drive. Also, those processes were never running on my computer and I could not find any other traces of them.
