Internet doesn't work on Win 7 Home Premium

Hi I have a strange problem.

The system was working fine for 3-4 months and suddenly it started giving me the below problems
  • OS > Windows 7 Home Premium
  • System is connected to internet and its works great on IE8.
  • Ram - 4GB DDR

  • Internet works only for IE8
  • All the messengers (Gtalk, Yahoo, MSN, ICQ) says that the system is not connected to Internet.
  • All the windows inbuilt functions (eg Win Help) says that the system is not connected to Internet.
  • All the other browsers (Firefox, Chrome, Safari & Opera) says that the system is not connected to Internet.
  • Antivirus softwares doesn't work. And are not able to do live update.
All the problem list has same reason " System is not connected to Internet "

Somebody please help me!!!

Check for possible malware infection. Next, check your "hosts" file (\Windows\System32\drivers\etc\hosts), the content of that file should only be ONE line (unless you manually put another line there). If that file have extra lines, then there is 90% chance of your computer is infected by some malware. I personally will suggest to unplug the system disk, mount it on another clean computer and scan it over there. Or you might want to try AVG's Live Antivirus CD.

Hi zzz2496

I checked the host file and have also scanned the harddrive connected on clean system and nothing was found.

My host file is as below;
# # source server
# # x client host localhost
::1 localhost
I tried removing last line but windows is not allowing my to save the changes on the file.
