Hello, for some reason recently, in Windows 7, I was not able to surf the website. While trying to fix the issue, I deleted some major files (due to some one saying delete x x x registry files) I forgot to take backup, now I am back to Windows Vista (for now). I am not sure why this happens. I contacted the site's admin and they said the site is working fine for everyone else. Here's my log of whats running

Also, in Norton security scan (From Divx player :P), it said 2 threats found and here's their picture.
I've attached it.

Obviously from the log file, I hid my GUID and my username, sorry.

All Help appreciated.

On first glance, this sounds like a DNS issue. Try using 4.2.2.2 as your primary DNS server, and see if the site loads. Remember to flush your DNS cache after making the change by running "ipconfig /flushdns" in a command prompt or the Run dialog.
