I hear clicks in the speakers but i did not click anything. These kind of click when you double click on the directory in the windows explorer. I don't know where is this coming from, also media player classic looses focus because of the worldsys.exe whatever is that.

What is happenning?

You might want to split this into 2 questions...

1) how frequent are the clicks you hear? Are they regularly spaced, or is the interval between different each time?

2) Worldsys.exe is a Microsoft exe (assuming that some malware isn't masquerading under that process name, as of course you can call your malware anything you like!) http://www.iobit.com/process/w/45/worldsys-exe-53412.html

I can hear this clicks like 4-5 clicks per 2 seconds(few series in 2-3 minutes and no more). They appear sometimes, for example had it 30 minutes ago while i was browsing web and yesterday during playing games. I use notebook(but i blocket touchpad) and they still were coming? –  Wojciech Oct 30 '12 at 0:20
was the notebook "locked up"/briefly frozen at the time? Or lagging, so that perhaps some mouse clicks weren't being actioned right away? I'm wondering if it is a system sound from an action you were doing. Do the clicks sound like the same sound each time, or are they more static-sounding, like a loose connection breaking and making contact? –  Jeremy Taylor Oct 30 '12 at 3:16
It is irregular. I can just play movie and this is on. –  Wojciech Oct 30 '12 at 9:47
Go into your Control Panel > Sound settings and go to the sound tab. Save your current settings so you can restore them later. In the Program Events list, go down and for each sound that has a speaker next to it, click the Test button to listen to it. Find the ones that have the sound you associate with the annoying click. Change each one to something else, but give each sound a DIFFERENT new sound. Make notes so you will recognise the sound. Now when you hear the sound, it will be a different sound and you'll be able to associate that with a particular notification. –  Jeremy Taylor Oct 31 '12 at 5:11

The Internet Explorer (or applications that uses it's engine) makes this annoying sound when auto-reloading web pages. Try a different browser for a while, and make sure you don't have any garbage applications that run without you seeing them.

I use Firefox. I got this sound and closes worldsys and it disappeared but I have to test it for one day to find is it this. –  Wojciech Oct 30 '12 at 23:50

This sound was plaguing me as well. Thought I had malware but a scan couldn't find anything. Finally used Process Explorer to track it down, Jeremy had the right idea with his answer. The sound is caused by 'Start Navigation' under Windows Explorer in Sounds. I believe the sound is played anytime you access the internet. I just changed the sound to none.
