Malware Detection Deleted My Pendrive Files

[Andrea_123 0]

Hi, so I was going to upload some files from my pendrive to my computer when It begins to "detect malware". I selected a file in order to upload it, and it was deleted, along with all the other files. I looked in the recycle bin and they were not there. My file history was not turned on, so a copy of those files on my pen drive were not saved. I don't know what else to do! Please help.
