I have Windows xp with MSN browser and e-mail. yesterday an e-mail appeared in my in-box ( I have no pop or anything like that) without a subject line from someone I do not know. I try to delete it and it will disappear, but if I leave the in-box and go to another folder (trash, junk, etc.) when I go back to in-box, the problem e-mail is back.I tried moving it to another folder and it will reappear in in-box with out moving to other folder. I have not opened it yet (it's 4kb in size). MSN says they can not see it on their end. I have sent an e-mail to the sender of the problem e-mail (it's a legitimate address) and he says he does not know me and never sent me one (I believe him). McAfee scan finds nothing, I have rebooted and it's still there. All other e-mails act normally, (delete, move, etc) All other PC functions are normal also. When I check my hotmail account (which gets the same e-mail as my MSN box) problem e-mail is not there. So it has to be locally on my PC. Any input will be greatly appreciated.
