The problem may be due to the update deleting your user Temp folder. The drive uses this when running the security software.
To access the location of this folder, you must first un-hide all files and folders. To un-hide the files and folders, right click on the Start button and select File Explorer, click on File at the top then on Change Folder and Search Options. Click on the View tab and select Show Hidden Files and Folders.
Once un-hid, go to the C: drive>Users>Username (where username should be your name)>App Data. If there is no file called Temp, create a new folder and name it Temp. Once this is done, try your drive again.
