One thought would be to look up trusted, open, DNS servers in your area....like openDNS...and add one or two to your router rather than letting it use the ISP's.
Google Public DNS: 220.127.116.11, 18.104.22.168, 2001:4860:4860::8888, 2001:4860:4860::8844
OpenDNS: 22.214.171.124, 126.96.36.199
Norton DNS: 188.8.131.52, 184.108.40.206
DNS Advantage: 220.127.116.11, 18.104.22.168
I had a slow down myself and decided to go BACK to using the ISP's and that resolved it for me.
You can also check your "c:\windows\system32\drivers\etc\hosts"
file and make sure it wasn't tampered with. Update your system and security/antivirus programs
and do a deep/full scan to ensure you haven't picked up a bug along the way.
Without any details, logs, or action items this is the best I can offer for now.
