My wife uses Yahoo and she gets emails daily from lbpcutie14@yahoo.com (someone we do not know) that contain a .pif file. I’ve always just assumed its a spammer and ignored it, especially since a virus probably wouldn’t be able to send itself through someone using Yahoo (so I guessed the spammer is using a fake return address).
Well today she received an email from my sister containing a file called your_file.pif. I called my sister and she said she does use Outlook but also has Norton antivirus and the email is sent out through her work server which has protections against viruses, so this probably wouldn’t have made it through. No one else has received such an email from her either.
How could this happen? Can spammers somehow figure out who is in someone’s address book (by taking an email forward) and use that as the return address? That seems like a lot of work, so my instinct is that my sister has a virus. If so, why would it only select my wife to send an email to? And how should she go about finding/removing this virus if she already runs Norton?
Thanks.
