start / type "cmd" / right click and "run as administrator" / type "sfc /scannow" and hit enter. this will run system file checker for fixing corrupt system files. It would be a good start.

Hi uls123,

Download and install WinRAR 32bit or 64 bit as appropriate to your system. WinRAR archiver, a powerful tool to process RAR and ZIP files

Safely remove all external hard disks and pendrives.

Shut down your computer and reboot.

Plug-in only the problem drive while pressing the left Shift key so that autorun is disabled.

Run WinRAR, navigate to the afflicted drive, click/double click on it to explore.

It will show all the files including the hidden files present in that particular drive.

Search for the file autorun.inf and open it with Notepad. Look for any .exe file entry in the text. This is the culprit that gets executed. Take a note of this .exe file name and close it.

Now that you know the name of the .exe file, search, locate and delete it from your PC. Also delete the autorun.inf file in your USB drive. (Right click on it and delete file in WinRAR)

Close WinRAR.

Now restart your Computer. Your system should now be free from the shortcut virus.

Is there any anti virus you're using? How about doing a full system scan along with scanning that drive? An updated security software may clean most of it, but if it's infected like hell, you will need to do a clean Windows reinstall.

After carrying out the procedure as aforesaid in post #3, run MalwareBytes Anti-malware booting your system into safe mode for an effective scan.
