My problem is with the IPv4 properties; I get connection when DNS is set to 'obtain automatically' but a few minutes after setting this, it changes to a preferred server called 127.0.0.1, the reroute to nowhere! Now i have to go back there every few minutes and change this setting if I want to connect.

Google was useless, I ran anti-malware, rebooted and reset all connections to both WiFi and Ethernet connection to the modem, tried all the command prompt tricks and nothing works.

do you have any other firewall/security suites on the PC like zonealarm
any trialware

I have seen this happen in emails because of a security suite

127.0.0.1 is your NIC. Also known as a loopback address. This issue can be caused by two common things:

Antivirus, Firewall or Security Suite > since you have AVG, recently they had an update that caused computers to lose access to the internet. Your version was the one I found the most issues with.

Malware > your computer may be infected by malware. If removing your security for troubleshooting purposes does not work, we would want to move this thread to Malware forum for a better look.
