Windows 7: Virus remains after formatting (bis)

Virus remains after formatting (bis)

Hey, guys, I have the same problem as the one in this thread.
I performed the recommended procedure:

3) diskpart
4) list disk
5) select disk 0
6) clean all
7) install windows

With no result. I even flashed my BIOS before booting on the windows DVD (while I did it from the desktop so I guess it's not enough but I have no clue how to perform that correctly). I must add based on this old thread that my windows DVD is supposed to be clean. I dled it with the help of the Microsoft Windows and Office ISO Download Tool which was recommended by How to Geek. Even if it was infected, I don't think there is a single chance it was infected by the exact same virus. I also burned on DVD the tool I use to detect the virus. It's not a false positive because a lot of shit happened. In fact, I installed a Linux and even on this OS, my connection had the same problem. They are a DNS and a browser hijackers btw. Oh and I didn't install any drivers so even if it want it couldn't connect to my router. Weirdly enough, it can detect the viruses only when I change the language for unicode softwares (and reboot).

Thank you for your help.

Maybe they changed some settings in your router. Try resetting it back to factory default. Then reconfigure it again.

Maybe try to use Google's public DNS. If you decide to try this, write down or take a screen shot of your present settings, just in case you need to revert back.

Google DNS

Preferred: 8.8.8.8
Alternate: 8.8.4.4

Here is a guide on how to switch to Google DNS. If you do a Google search for, Google DNS, you can find more.

Do you have any other PCs on the same network as it may have jumped to them have you done a factory reset on the router

I don't understand why both of you are talking about my router when I said this PC can't connect to it even if it wanted like my network card doesn't have any driver installed... It seems to not be the problem.

W7 comes driver complete, so it doesnt matter if you havn't installed the genuine ones, MS pushes a generic driver to the device.
The ony way to check is in device manager, general tab.

Sorry for the extra long wait.
So, first, MS didn't install drivers for everything that was under network card. First time I formatted, I had to install drivers to connect to my router.
Second, I redid the whole procedure with my router and my second infected PC turned off. So no network at all. Still infected.

At this point, I think I can say that diskpart is not 100% efficient. On the other thread, they are debating if diskpart is working against bootviruses and someone said no but how is it true when diskpart is run like a software from the booted DVD, i.e. after a bootvirus is supposed to be activated?
Any other solution than diskpart, please?

How do you know you have a virus?

diskpart WOULD CLEAN THE DISK AND INSTALLING A CLEAN COPY OF WIN 7 WOULD REWRITE PARITIONS AND mbr BOOTSECTOR. So unless you are installing something thats infected it should be clean.

Is it now connected to the internet?

I think that OP knew the virus
Quote:
They are a DNS and a browser hijackers btw.
but did not remove them before continue.

Then OP mentioned on not to install drivers, again thinking the virus is on the drivers.
This is where TrustMe and you come in.

But torchwood mentioned
Quote:
MS pushes a generic driver to the device.
but OP still unable to understand.


The problem lies in OP mind keeping searching other forums.
Jumping from one forum to another, it will not resolved the problem.

If solution is not resolve, then move on to other forum.

Read OP 1st post.
From one old thread here, and then move to another forum "recommended by How to Geek".

Now come back after weeks, which OP is still searching on others forum...

Maybe the OS you are trying to install comes with a virus?
