Applications cant connect to internet

hi

I have come across a strange problem ,here's how it is

I am unable to connect certain applications to internet such as pop peeper , filehippo application updater, wallpaper downloader and also when I ask an application to update itself automatically they give an error that says cannot connect to internet .

My internet is working fine , no problem in browsing , internet download manager ,utorrent and all so i cant understand why it is so ?

I have zonealarm firewall and according to my understanding its not blocking the applications .So please suggest me a solution
