im having the same problem with my USB flash drive. The files didnt turn into shorcut folders BUT it created a shortcut for my files(removable device shortcut icon). The files are not hidden, they can be viewed once I opened "removable device".
im looking for a solution for this problem, can anyone advise me what to do? ive tried to remove the autorun.inf and the said "virus" using the cmd prompt, and formatted my flash drive, but unfortunately once I plugged back my flash drive it turned again into a shortcut.
If you have virus then scan your removable device. Pick any antivirus like Norton, Kaspersky, Immunet Plus, Bitdefender, Avast, Avira etc. (if you don't have) and scan your removable device after attaching it to system. Virus will be detected and will be automatically removed. When virus is removed from your removable device, don't forget to scan your computer completely, so that every single virus is removed and you don't suffer from this problem again.
