Hi there I Know there is not many known Trojans or whatever for mac but I know they do exist. I recently was in need of Microsoft office 2011 so I downloaded a a pirated copy of it. So when I installed this pirated software that i downloaded from piratebay I installed it and during the installation it made me put my admin password in in order to install it. If I recall the only way a trojan can take ahold of my computer as if I installed some program and gave it my admin password. Im very worried about this now as I always handle valuable information on my computer. The software had more than 1000 seeders on piratebay. Could this be a trojan in disguise or keylogger that I gave it permission when i installed it with the admin password it asked me for. Could this bypass my little snitch? or if it was trying to send something out would little snitch inform me? Am I being too paranoid? Should I format my computer or is it not neccesary? Id rather not go thru all that work of formatting just for being paranoid.
