Hi there. I don't know what it is at all. I have just searched using mamma and also looked on my computer here at home and nothing was found.
Are you sure it is the correct spelling?
Incidently, whilst scanning for this file my anti-virus found this trojan on my system--- Trojan.ByteVerify could be something to do with a virus as you say.
Sorry I am not much help here but I thought you would like to know what I come up with.
