Windows 7: Can't go online via software

Hi,Running Windows 7 64bit,and the problem is i can go online via FF or IE9 but if i try to go online via for example right clicking on a dropbox folder and choosing share folder nothing will happen.
Or if i try to go online via software for example anydvd if i click slysoft when i right click icon nothing happens.
I remember this phenomenon happening before a long time ago and i was given a fix for it,but for the life of me i can't remember what it was.
Would be eternally grateful for a solution to this problem.

Download and install Malewarebytes in Safe Mode:Malwarebytes Anti-Malware - Download.com
Once installed and updated, run a FULL scan, not a quick scan. If Malwarebytes finds anything, remove all of the viruses that it finds.

Hi, Thanks for your reply.I do run Malwarebytes Pro quite regular, but i just took your advice and run a full scan in safe mode and it found nothing.
Like i said in my first post this problem happened to me once before a long time ago and a mod give a fix for it. I think it was along the lines of my computer and properties but not sure.
I've made a short video of the problem which might explain it better than i can in words online problem - YouTube

Are you using a 'proxy'?
What is your Anti-virus and Firewall?
Have you purchased the software?

Sorry i'm an average user could you explain using a "proxy".I use Malwarebytes Pro and Avast 7 freeware and Windows firewall.

This should explain:Proxy server - Wikipedia, the free encyclopedia

As far as i know i don't use a proxy server,but i have got dropbox installed.

Just had a brain storm and remembered what the fix was it sort of goes like this,start/default programs set program access and computer defaults/microsoft windows/non microsoft windows/custom/ and set ie as default and bingo it's fixed.
I should imagine there's a lot easier way of doing it than the way i did it.
Thanks for everyones input.

So, is it fixed or not?

Yeah i did say "bingo it's fixed"
