Try one of the many Live CD/DVD/USB OSes like Linux Mint to check out the hardware. Repairing such infections is a lot of work and since I've yet to find two the same, your choice to just reload and avoid the bad sites that created the mess.

Ok so I'll keep this short as I can :
-Have an household with 3 computers, 2 wifi laptop and desktop pc, 1 wired desktop pc
-My internet works on wifi, works when I wire my ps3 with the same ethernet cable than my desktop pc (with it's wifi off, of course), the little icon down right of my pc screen says everything is fine, same thing in config pannel it says ''Internet Connected''
Here's the problem : Google Chrome won't work, every other internet related program wont boot (skype, steam, other browsers like IE)
I managed to get google to connect by changing some file name to ''Google Old'' or something as I saw in a troubleshoot, works but as soon as I load another page it disconnects again..
This happened after I both download a Windows Update (that I then tried to disinstall... didn't work so far) and a strange blackout that disconnected the second desktop pc for a day (it was turned back on before mine afterwards, if this changes anything...)
So I tried :
-Every single configip command that was related to my problem in any forum I found, same thing with the Netsh Winsock reset and other commands
-Setting a DNS server manually (people told me it could help.. didn't so it's all back to normal now)
-Delete my anti-viruses
-Delete all recent update
-Backup to when problem happened (said something was causing an error, wouldn't work even after disinstalling anti viruses, now too late last point is after my problem happened)
-I disconnected all PCs in the home and both the router and modem... waited for a good 5-10 minutes then rebooted... not working
I probably tried a lot of other things I can't seem to recall atm ( been working on this for about 2 weeks now...) but now I'm at the point where I would deseat, reseat, factory setting and everything -.- I'm starting to think it's a damn genius of a virus
So now here I am, creating this account in a rush seeking your expert help
if it can help you out... google chrome tells me the error code is ''DNS_PROBE_FINISHED_NO_INTERNET'' but googling that gave me no working results
(Seriously if anyone fixes this I'll love him till the end of my life, give him some stuff on steam, ANYTHING lol)
