can't download combofix

You have a Ramnet infection in place, I don't want to give you any false hope, but you don't look in too bad shape. Usually these sorts of infections wind up with people having to reinstall windows. Let's have you run a scan and see what the results are:

Run this three times and attach the results of each scan.

Using ESET's Online Scanner

Then:
Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this.

 

Ramnit infections have really become quite nasty and dangerous. We could attempt to remove it, and we have had some success in the past, but recently it has become even more troublesome to remove. It is really safer to just bite the bullet and do a clean reinstall.

The problem is that the damage caused by this infection really makes a PC unreliable/untrustworthy. PE file infectors like Ramnit, Virut,.... etc can infect all executable files (DLL, EXE, SCR....and many more and also HTML). These infections can open back doors that truly may compromise your computer and your security. These backdoors could allow a remote attacker to access and instruct the infected computer to download and execute more malicious files.

In many cases the infected files (which could number in the thousands) cannot be disinfected properly by your anti-virus or by other scanning tools. Also when disinfection is attempted, the files often become corrupted and the system may become unstable or irrepairable. The longer Ramnit remains on a computer, the more files it may infect and/or corrupt so the degree of infection can vary.

Ramnit is commonly spread via a flash drive (usb, pen, thumb, jump) infection where it copies the Ramnit worm using a random file name. The infection is often contracted by visiting remote, crack and keygen sites. These type of sites are a major source of system infection.

It is for the best that you perform a clean reinstall of windows.

 

You should run the Read and Run Me First procedures again and attach all of the requested logs. But best to create a new thread as opposed to merging with this one here.

Also run another ESET scan...see if it is finding any Ramnet.
