Alright, my sister's e-mail got hacked (again ), but looked legit so I opened her e-mail and clicked on the link there, which took me to another site that was blank, but immediately upon entering the site, a file called "supor....exe" or something was downloaded into the Downloads folder. I immediately sent it to trash and cleared the trash. Should I be worried? Are downloaded files executable upon the download or while in the folder? Opening the e-mail in my parent's PC, Microsoft Essentials blocked the download as "malicious". I was using Safari. MBP works fine but I'm afraid it got infected with spy ware or key logger trojan or something.
