I wish.

But whenever I click on the link provided in that thread I get an error page saying:

The domain "u40.eset.com" is invalid.

 

If u mean this link http://u40.eset.com/download/engine4test/
its not a webpage, its a update server for nod32, u have to enter it manually in the update options.

 

I entered it in, but I got an error message saying:

Can not connect to server.

 

Mmm, maybe u still have the problem with the hosts file, it blocks access to some ip's. U have to edit it, its located here Windows\system32\drivers\etc\
Open it with notepad and delete all the entries u'll see there, for example, mine only have this line

127.0.0.1 localhost

U can leave it blank if u want. Dont know if that's really the problem, but let's hope it can help u.

 

How do I go about accessing Windows\system32\drivers\etc\ ?

Do I use Windows Explorer ?

 

Yep, system32 is a hidden system folder, so maybe u have to enable the option to see that folder.
U can make a manual search too, and look for that specific file.

 

What part of the following should I delete?

# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.

# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

127.0.0.1 localhost

 

Ur hosts file seems fine. If that's all is inside the file, then that's not the problem. Are u still having the problems u had yesterday when trying to access those pages? If so, then is a DNS problem, but not with the hosts file, u said u could have problems with your router, what router is it?

 

Yes. I am still having the same problems.

I don't know the name of the router at this time. Because one of the guys who lives in the house owns the router and he is at work right now.

When he gets home, I'm going to ask him to re-set his router.

 

Ok, but before reseting the router, u can try to access the pages in the other PC that is connected to the router, if u can access them from that computer then it's a problem in ur PC, if not, go ahead and reset it to see if that helps.

 

I just got into an argument with the person who owns the router. He doesn't trust my information and he made a threat against me. He told me that if something goes wrong then it's going to be on me and that I will have to pay for a new router. Well I don't have the money because I am on SSI. So I told him to just forget the whole thing.

So meanwhile, I can't update NOD32 4 Beta.

So I went around looking for another antivirus program that will let me update and I came across the online scan of Panda Antivirus. The online scan found over a hundred viruses on my computer but would not clean it up unless I paid 12 dollars.

So I got the idea of downloading the trial version. But now I ran into yet another problem. It's not in English. I can't find an English version of the program.

 

Well, you clearly have DNS issues that need to be solved (or your hosts file location has been changed from the standard one via some malware in registry). There's no point in messing with various download locations because your AV will NOT be able to update until you fix your DNS.

You can check for the actual location of HOSTS file that's being used by checking the following key via regedit:

Code:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\DataBasePath

The REG_EXPAND_SZ value should read: %SystemRoot%\System32\drivers\etc

P.S. A reboot is required for the registry changes to take effect!

 

I can't find the DataBasePath part in my registry.

 

Shrug; so add the key? I can, that's all I can say here. You should also check your system with something like Dr. Web CureIT or whatnot as it can quite possible be infected with some kind of DNS hijacking trojan.

 

I am in fact infested with the Trojan.DNSChanger.

 

Good to hear u found the origin of the problem, i hope u can update nod32 now that u know what was the problem.

 

The definitions that came with v4 are not so long . Could you please check if ESET now detects this trojan and if not send a copy of it to ESET Labs - samples@eset.sk

 

Yeah. But I'm still totally screwed because there appears to be no way to get rid of the Trojan.DNSChanger unless the router is re-set. And like I said, the owner of the router doesn't want to do it. We had got into a fight about it.

I have spent the past couple of days trying to find a different way to go about without having to re-set the router, but nothing at all has turned up.

 

Maybe the router is not the problem because u found the trojan in ur computer, so is more likely the problem is inside ur PC, another person had the same problem and it seems he could solve it using other tools

Maybe it can help u.

 

Thank you for the link. I looked at it, but it really didn't help me any because it didn't tell me how to go about deleting the items:

Delete what files?

Change what registry entries?

 

Go and register in a forum providing malware cleanin services . They'll guide you to a way of eliminating any threats from your computer and the side effects . I'd recommend AumHa forums

 

Thank you for the link.

I just registered and posted there.

 

Please send a log from SysInspector to samples[at]eset.com with this thread's url in the subject.

 

I wish I could. But unfortunately I had to uninstall NOD32 several days ago. I didn't want to uninstall it. I like the program. But not being able to get any updates rather defeated the purpose of having it on the computer.

What I had to do was install a different antivirus program that would update (after a work-around that finally let me do it).

If I ever manage to get rid of the Trojan.DNSChanger, I will probably go back to using NOD32.
