Facing issue while trying to disable automatic discovery of devices through Apple Bonjour

Question

Hi All,
I am facing issue while trying to disable automatic discovery of devices through Apple Bonjour.
Background: Whenever our application is in running state, devices are automatically discovered if it connects to PC. We are using Apple Bonjour's auto discovery technology( mdnsresponder ).
We are registering a particular service type by using DNS API "DNSServiceRegister". Service type is getting registered properly and we are able to discovered that particular type of device.
Platform:  Windows 7.0 / MAC 10.8
Issue:
But we are facing issue while trying to disable auto discovery of a device programmatically. i.e, unregistered a service reference programmatically from our windows application.
To unregistered a service we are using "DNSServiceRefDeallocate" DNS API. But looks like it is not working properly.
Is this DNS API “DNSServiceRefDeallocate” is correct one to unregistered the service?
Here is the step by step procedure that we are following to de-allocate a service reference:
1.Browsing / Query a service by using service type to get service reference (DNSServiceRef). 
2.Get reference socket FD by using DNS API "DNSServiceRefSockFD".  
3.Select a socket by using "select" API.
4.Close the socket that we got from step 2 by closesocket().
5.Delete the service reference by using DNS API "DNSServiceRefDeallocate" and service reference from step 1.
Are we missing any step to unregistered a service? 
Regards,
Goutam

Original problem I noticed was that regular websites I go to (such as msn) were only partially downloading.  I could see the text on the site but no pictures or videos.  All web surfing was extremely slow.  When I would go to a site such as man I would see another address in the lower left corner for "ads1.msads.net" or "cdn.optimizely.com" that is was trying to connect to. I tried using all three of my browsers (firefox, safari, chrome) and got the same response on all browsers.  After I spent some time researching the issue I decided I probably had a adware/malware problem so I decided to try adwaremedic.com.  I could also not access that site along with thesafemac.com or apple.com.  I was also getting the same response on my other devices (iPhone, iPad, and a mac air).  I could not access any of these sites on any of my devices although I could get to almost any other site although it was very slow.  At that point I decided to unplug the router.  I also did a number of other things before then to try and manually get rid of any adware.  Eventually I got msn back working, apple.com, and the speed was much faster.  But, I still can not access adwaremedic and thesafemac.com.  I could access these on my phone with 3G but not on my wifi.  This is where the problem still stands.  I am sure I still have some adware on my computer and need to find a way to remove it.  I am no techie so the complicated manual fixes are difficult for me to do.
