Set the DNS
open dns use 208.67.222.222 and 208.67.220.220
google dns 8.8.8.8 and 8.8.4.4

Try using OpenDNS and see what happens. Though it seems like virus as you said it's working perfectly after formatting and behaving wired after some months. Try to run an online scan.

yaa, the same problem happen twice in my system too. I post that problem in many sites (also here). And I got too many replies including the DNS address change. But nothing works. I think reinstalling the XP is the only one solution. I have done online scan using some sites and also scan with different anti virus, spyware / malware softwares, but nothing found. Also post my "hijackthis" report in some sites and they said nothing wrong in that. I am reinstalled my system and currently it works fine. Try different antivirus softwares.

Which Windows version ur using? use windows XP sp3 (if ur using XP)

It's not becoz of any virus or spyware / malware attack.

I think prob. is becoz of antivirus. use diff one. probably lighter one.

And don't install too many softwares or don't try tweak windows registry.

Just keep light

Right Avast can cause such problems switch to AVG. Also see if the website loads when
firewall is turned off.

Check if ur CD itself is not containing any virus!... Use some another CD/image!

This is a DNS changer trojan, I'm sure...
had the same problem few months back...
My DNS kept on changing, pointing to some chinese/taiwanese site
I used AVG free and malwarebytes malware scanners, try these, never had this problem again...
OPEN DNS is a excellent alternative , use this, also check if ur DNS keeps on changing each time u restart the PC, regdless of the scanners etc... u have
Try this and post ur results... should work...
will give u some links later...

If you are using anything like tune up utilities to change windows settings, that might be causing the problem. Don't use too many anti virus or anti malware programs. If you have installed a firewall, check its settings or try disabling it. for anti virus, use Avira & keep it updated. check the proxy settings of the browser, it should be set to do not use proxy or set to nothing. empty the browser cache & delete all cookies. you can use CCleaner for this purpose. do not fiddle with the registry or services unless you know exactly what you are doing. Lastly, if nothing solves your problem, try restoring windows to an earlier date before reinstalling.

check ur hosts file for any changes made.
