Changed dns after running namebench, current dns was slow.
Downloaded Chrome, Opera to see if better than firefox, Opera exhibits similar behaviour as firefox, websites hanging etc. Not really tried Chrome.

Try 2 If First doesn’t work
Could you try switching your router back to original settings
and change DNS by changing the IP Properties of your computer?
and try changing them to Comodo SecureDNS and see if it still slows down
No, change only DNS to address provided by your ISP. If you haven’t noted it, you can enable “Obtain DNS server address automatically” option or try Comodo DNS. Here is explained how to do that.
Also, check your hosts file that is located in the following directory: C:\Windows\System32\drivers\etc\hosts. Open it with Notepad and upload a screenshot of it, so we can see if there is something wrong with it.
# Copyright (c) 1993-2009 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
# 184.108.40.206 rhino.acme.com # source server
# 220.127.116.11 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
There must be no extra websites listed.
What’s your security setup right now?
S&D is not good anymore. You can uninstall it, install MBAM and run a scan to make sure that this problem isn’t caused by some kind of malware.
If you’ve used the “Immunize” feature in Spybot, your HOSTS file is filled with ■■■■.
Large HOSTS files are not recommended because they cause system performance issues. This is because the HOSTS file is not an indexed file. So each website you visit, your system must read the HOSTS file from the beginning each time to see if a site is listed or not. If your HOSTS file is large, you can see this would adversely affect performance. I can’t remember the size, but I think you can start noticing slowdowns if the file is larger than 250kb.
Some sites that supply large HOSTS file lists recommend disabling the Dnscache service to avoid this slowdown. The net effect now is that your DNS entries aren’t cached locally. This will slow down your browsing because each and every URL now triggers a DNS lookup because it can’t use cached results.
I would definitely recommend not using the “immunize” feature for this very reason. Spybot will have made this file read-only, so I would clear the read-only flag and delete the countless entries Spybot has added to your HOSTS file.
