The host file is same as below..but even then problem is still there and
only google and msn websites are opening and no other website is opening.
Arsalan,
If you're still having this problem, and you've checked the LSP/Winsock and the
MTU, and you've looked at the (known) hosts file, there are additional
diagnoses:
1) Examine the contents of hosts, using Notepad, carefully. Scroll to the end
of the file, by hitting Ctrl-End, then back up to the top, page by page, before
deciding that any "hosts" file is empty. Look out for blank lines at the
beginning and end of the file, after "localhost", placed there by an exploit.
Do not assume that a file is empty simply because you see "localhost" followed
by 50 blank lines!
2) Check Registry key
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DatabasePath].
Is its value "%SystemRoot%\System32\drivers\etc"? If not, check the hosts file
in the folder indicated.
3) Check for a spyware hijack (probably a DNS / hosts hijack) of a currently
unknown variant. The bad guys are being paid to do their work, and they are
becoming very good at it. There's a lot of $$$ in hacking (cracking) currently.

Create a separate folder for HijackThis, such as C:\HijackThis - copy the
downloaded file there. Create a separate folder for the two TrendMicro files,
such as C:\TrendMicro - copy the downloaded files there (unzipped if necessary).
AdAware, CWShredder, and Spybot S&D have install routines - run them. The other
downloaded programs can be copied into, and run from, any convenient folder.
First, run Stinger. Have it remove any problems found.
Next, close all Internet Explorer and Outlook windows, and run CWShredder. Have
it fix all problems found.
Next, disable System Restore.

If removal of any spyware affects your ability to access the internet (some
spyware builds itself into the network software, and its removal may damage your
network), run LSP-Fix and / or WinsockXPFIx.
