unzip

Every time I turn on my Mac, my Zipeg program opens up and asks me if I want to extract a file called "SafeConnectMacInstaller". It just happened a few weeks ago, but I don't know how to get rid of it. I tried extracting it but it still shows up every time I start my Macbook. I don't want to...

I've tried multiple commands but I either keep on getting "permission denied" or the the directory doesn't exist...

I have wiped my laptop and all the music from i tunes has been sorted in to zip files and i am not sure how i can unzip them and put them back in Itunes

I got some saved game data off the internet for my psp and I can not figure out how to unzip it could someone please help me.
