|Not keeping it is probably your best bet. Note that just plugging in the flash drive can reinfect your computer. If you change your antivirus program first, scan your computer, then plug in your flash drive but do not open any file or folder (close the pop up window that asks you what you want to do with the drive). Go to Computer and right click on the flash drive and see if the menu offers the option of scanning it with your new antivirus program, if it does, choose that option. If it does not, open the antivirus program and start a scan but make sure that it includes the flash drive. Then download, install, update, and run Malwarebytes free version make sure that the flash drive is included in the scan (during the install, uncheck the free trial or you will not get the free version). Malwarebytes should also be added to the right click options for files and folders but scanning the entire computer at this time would be preferable. Remove all it finds and delete items in quarantine. Copy and paste the both logs here for review. Depending on what is found, others may recommend other things to verify it is clean so do not try opening any folders yet.|
You have to be a little bit crazy to keep you from going insane.
