After a while of being redirected my internet shuts off completely on the current PC, even though it is still connected to the network successfully, and even though it has been proved the internet is working (Internet Explorer/Firefox/MSN/Steam, most internet apps stop working, yet I know the internet is still working because I can connect to various update servers, and downloads keep going e.t.c).
I have: 1) AVG Free Edition, 2) Spybot - Search & Destroy, and 3) Adaware 2008 Free Version. 4) Malwarebytes Anti-Malware
1) AVG finds nothing wrong.
2) Spybot finds something called DNS.Changer (or something like that). When "fixed" it shows to fix, but upon reboot and re-scan, it reappears untouched.
3) Adaware finds the regular nonsense of tracking cookies that everyone gets, but it also shows 5 IRREMOVABLE host file entries. The program doesnt allow me to remove or quarantine them. After removing them in the hosts file by using notepad, and saving, they just reappear back there after reboot.
4) Malwarebytes Anti-Malware finds the same DNS.Changer spyware that Spybot finds, as with Spybot I can remove/quarantine it, but it simply reappears each time I scan.
My whole family is having to put up with this and nothing we do seems to work. Please help.
