Can't load certain webpage in IE, FF & Chrome

Hi all,

I have had this problem for a while. I cannot access certain websites I used to visit regularly from any of the 3 browsers that I have installed.

One of these websites is: https://wiki.d-addicts.com/Main_Page

I have gone through many threads in this forum and others and tried different solutions without success.

I have also scanned for virus, malware, etc using Avira Premium, Malwarebytes, Spybot and CCleaner.

I have also created a backup of the old hosts file and made a new one following the instructions from MS KB site.

I will appreciate it a lot if any of you can help me out
