It's probably a "gift" from duiops.net. I would do the scans, and check that the seres is mentioned in the scan report as dangerous. If you can't see it there, you can do a normal search for the file, and delete it manually. As far as I can see, no seres anything is vital for Windows.
EDIT: Might be wise to avoid duiops.net? Or at least improve your protection level?
