I am running windows 7 professional with the free version of AVG fully updated and ive had this virus for about a week and what happens is it changes all my folders on any usb plugged into my computer to shortcuts.
Originally, I accidently opened a bad mail attatchment from kingdom of loathing and my compuyter kept comming up with critical system errors, basically a scareware and it changed all my folders on my computer to shortcuts, i couldnt access regedit or any applications and when I clicked on a shortcut folder a dos prompt would come up and dissapear. So I formatted my computer and all my external HDD's and it fixed my computer anyway.
Now, every time i plug in a usb stick or external hard drive it changes the folders. I did some research and managed to get the folders back and found a suspicious folder on every usb stick called RECYCLER inside it is an .exe called 686c1039.exe and a desktop.inf I have tried, AVG anti virus, Malwarebytes, spyware search and destroy and none could detect it. I also used autorun.inf eater which found a bad autorun.inf on all the external drives, which It deleted. However, when it deleted it and i took out the HDD then plugged it back in the RECYCLER folder and the autorun.inf come back. I should also not a file which I beleive is an .exe (with a recycle bin icon) appears occasionally.
I took one of my usbs to uni to do some work and when my freind plugged in their external HDD with my infected USB the virus went onto his external HDD. So what we did was take the now infected HDD put it on a new computer, took all his files off of it then unplugged the newly infected drive and put in a new drive and put all the files on that. Which worked. he has used it for a day with no issue
I read a tutorial to find some bad registry entries which may be the problem but could never find exactally what they asked for on another forum. From memory it was in the HKEY software folder in windows then explorer and they had me look for a hide or super hide entry which wassnt there.
For the last day I ended up formatting all my usbs and externals and my computer again. Which I thought worked because the RECYCLER folder or the autorun.inf never came back no matter how many times I unplugged the drive and plugged it back in. Great I thought, then I decided to try another laptop with vista and outdated mcaffe antivirus. Soon as I plugged in the external its back. However, when I plugged it back in my computer and deleted the autorun.inf and RECYCLER folder and repaired the folders, formatted the external HDD then took it out and plugged it back in its fine on my computer. One way I know this is when I suspected I had the virus it wouldnt let me eject the HDD, saying it was used by another process. That has stopped now
If anyone can help that would be wonderful as im trying to fix my freinds external HDD.
I should also add after formatting all the drives and my computer again the autorun.inf never comes back nor the RECYCLER.exe it just changes the folders to shortcuts and makes the real folders hidden system folders.
I hope I have put enough information here and Im happy to provide more if need be.
