defo don't open the email. it's probably a virus. happened to my husband once. I ended up having to re install everything on the pc.
If you wanna look up sex offenders I'm sure you can Google it. safer

Never click on links in emails. I actually never even open emails unless their a contact. Sometimes evening opening an email can be spam or contain a virus.
