So for whatever reason...I tried out MacKeeper... It told me my computer was in critical condition, with flashing red lights. I couldn't do anything, though, without paying. Is this accurate, and if so, what should I do? I don't mean to sound like an idiot, but I have noticed mac slowing decent bit. Other users here advised me to 8GB ram/SSD, but I wonder if this is the cause. If so, is there any free way to clear this 'infected' files? I could torrent...but I figure that's how the files were infected in the first place. I apologise if MacKeeper is simply full of **** and I fell into it.
