Is the mac so safe now?

[B1G_BR0TH3R]

i feel almost postive now that my mac has some sort of infection, it runs ALOT slower than what it used to when i first purchased it, and often overheats to some extreme temperatures (not sure if that has anything to do with it)
i have sufficient space remaining (80 gb) so its not like that is an issue.
macbook pro. and i'm upset with its current performance

you just have too much crap laying on the desktop
