Unbelievably malicious malware, urgent help required.

Hey, my PC recently contracted a very malicious piece of malware, after Avast notified me of the virus, saying there was some malware, I tried to do a scan right then with something but the virus disabled Avast, Windows Defender, Malwarebytes, the Security center and blocked internet access to every antivirus website I've tried to to reach so far...

Downloads get to 99% but do not finish outside of Skype.

Quick and even full scans with Malwarebytes (chameleon) and the MVT do nothing, after identifying the trojans and the hijacker and restarting, the malware is there again after a little bit, slowing my PC down to mollasus and compromising everything again... :huh: :huh: :huh:

I've noticed that the malware/virus seems to kick in after my router beeps twice, so that probably means that the virus is rooted deep in my network somwhere. :eek: :eek:

I've tried restoring my system to a few days prior to getting the infection but to no avail, it just tells me it isn't working every time via a pop up message.

Here is the report from the aftermath of the full scan I performed with Malwarebytes, due to the nature of the infection, it took 12 hours!

I really believed that the full scan would detect the root source of the problem and I would be able to handle it on my own, that's why I waited so long.

Restarted the PC and did another quick scan and as you will see, the stuff is back again.

You have MalwareBytes installed so try this
Go to your program files (not the start menu shortcut)
and click malwarebytes
Then click Chameleon
then click Chameleon.chm
click the top box where it says Chameleon#1

Thanks a lot for the reply, yes I've just tried it, I'm not sure exactly if it was any different, I switched to safe network mode and now I'm able to scan with Avast for some reason, I'll post the results when it's done, but it's taking a very long time and I'm going to have to sleep soon, it's 3AM now.

Doing another scan with MWB aswell, see it finds anything else like a rootkit.

Also I cannot update my avast in any way.
