Is it possible for an outside contact to erase emails from a desktop computer?

Question by Thaylen M: Is it possible for an outside contact to erase emails from a desktop computer?
I have specific missing emails and I don’t know how they were deleted from my sent file and also they are not in trash. Other emails that I sent out on the same day as the missing ones are there and also older ones but NOT the ones going to this particular business and an email referencing a complaint about this business is also gone. Any clues?

If you dont have security(firewall,anti-virus, spyware/malware removers) then yes someone could get into your machine and remove infomation.
