If not already loaded, I suggest you download, install, and update malwarebytes (from malwarebytes.org, get the free edition). Run a full scan and delete all it finds. Make sure you scan with the USB drive connected so it gets scanned as well.
What else is your system doing that seems odd? What anti-virus program are you using?
