Shared list in finder doesn't appear

from time to time the shared list doesn't show up.

it kinda goes on and off without my consent.

I am afraid my computer's hacked seriously, and I know for sure that it's true because it's not just this case but other miscellaneous stuffs like icon arrangement in launchpad or settings, application cache being deleted without me knowing and etc.


but my question is how do you turn the list on in finder?

 

I bought my MBA 11" about 6 months ago.
and I always keep my macbook as clean as it can be, as latest as it can ever be.

I'm not just assuming that it's hacking attacks.
My network packets get retrieved by someone else i don't know, and seems that they get information from the packets and proclaim that they' know it all' about me.

but im not just talking about that issue here.

It has been slowing down a lot recently, (actually since 3-4 months ago already) and it takes almost 5 seconds to open a website like this which would normally take less than 1-2 seconds.

I cleaned the entire cache and trashes using tools like OnyX and many others.
I cleaned the PRAM and so on.

It would work fine then, and then when hackers start attcking again it slows down like hell.

certain patterns appear on my screen - which is hacker's mischief for sure.


I think you should really answer my question rather than talking about what you think you know.

 

Despite what your discretion tells you to say, my comments DID NOT verify that my macbook is NOT hacked.
I know what i talk about when i write things. I am also a web designer and a programmar.

Has it ever crossed your mind that I might be understanding my own circumstances far better than you are?
not to mention that I answer every question you asked above just for your convenience.

I do appreciate your service but you clearly have no idea what im talking about.

I did come here to seek answers, but you start talking about entirely different things which seem to gratify your ego but never answer my 'real' question and you claim to know my personal experiences better than myself, which I highly doubt the possibility,

and what 'experiences' are you precisely talking about?
