I got some strange file from my university. I mean I have received a email from my university where I found chinesep.pps file. It is an attachment file on that email. I don’t know who sent me that file, i.e. I have received the file from some unknown person and he is using university mail ID. I am confused about it whether should I download and run that file. So I want to confirm about this as I doubt it as a virus file. So please let me know what exactly the purpose of this file is.
