Full Version: Problem with internet connection
Gladiator Security Forum > Malware Help Forum > HELP! Think you are Infected?
mavplz
My problem has started few days ago. I have WinXP SP2 and ADSL internet connection. I ve never had any problems with it but now, when i try to connect with Internet, there is a message like "cannot establish connection" (i have Polish OS so i just translate... in reality it may be a bit different, but i hope u know what i mean). So to connect i have to restart a computer few times and it is the only way to make the connection work. I did a scan by the newest Ad-Aware, Spyware Doctor and HijackThis. Ad-aware found nothing. Spyware Doc found few infections and deleted it. Hijack also found few dangerous logs, and also deleted it. But the problem is it didn't solved a problem. Every time i connect to internet, restart computer and make a new scan, there is the same situation: identical infections appear again. In Hijack there are two logs i can't delete:
1) R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyServer = 211.142.211.39:8080
2) O17 - HKLM\System\CCS\Services\Tcpip\..\{3C08CBDB-2261-4A71-A965-34F67B93A9F9}: NameServer = 85.255.113.78 85.255.112.36

The same situation is in Spyware Doctor. It finds all the time the following infections:
1) Application.NirCmd
2) Trojan.DNS-Changer
3) Trojan-Downloader.Popuper

I can delete it many times but it will appear again.
I looked for some info about DNS-Changers and i found out it redirects some porn *tube like sites into other. I tried to enter redtube, porntube and it truly redirects me to other addresses: http://216.255.178.179/ or some fake antyvirus sites (like http://virus-scanonline.com).
Moreover, i switched the realtime protection of Spyware Doc on and when i try to connect to internet, it blocks connection and show informations that my internet connection is a Trojan Downloader. Also tried do a system restore but it didn't help.
I completely don't know what to do... Any ideas? THX in advace!

Here is my Hijack log:

Hello mavplz,

Welcome to Gladiator Security Forum hello.gif

You cannot delete the 017 because that is part of the infection you have, which we call Wareout. We'll fix that.

As for NirCmd, I have to assume you've run a couple of tools to try to get rid of the infection, because that file is used by some of our tools and is legit. AVs tend to pick it up as bad, so FP there.

And on top of everything, what do you expect by going to places called PornTube???!!!??? If you're going to let this nasty stuff in, you'll always be infected! OMG.gif I only see one lone entry for Kaspersky....is it up to date?

You may want to print out these instructions for reference, since you will have to restart your computer during the fix.

Please download FixWareout from one of these sites:
http://downloads.subratam.org/Fixwareout.exe
http://download.bleepingcomputer.com/lonny/Fixwareout.exe

Save it to your desktop and run it. Click Next, then Install, make sure "Run fixit" is checked and click Finish.
The fix will begin; follow the prompts. You will be asked to reboot your computer; please do so. Your system may take longer than usual to load; this is normal.

Once the desktop loads please post the text that will open (report.txt) and a new Hijackthis log.

Thanks,
tea

I have Kaspersky installed (it doesn't report antything's wrong!), so i suppose it's up to date.
Actually, i rather not use porntube like sites and i don't mind it doesn't work, i mind that there is sth bad with my computer....
I am waiting for next instructions :)
teacup61
Hello,

Check your Kaspersky manually to be sure....just to be sure, because I'm not. You can delete FixWareout.

Please download Malwarebytes' Anti-Malware from one of these places:
http://www.majorgeeks.com/Malwarebytes_Ant...ware_d5756.html
http://www.besttechie.net/tools/mbam-setup.exe

Double Click mbam-setup.exe to install the application.

* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Quick Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire report in your next reply along with a fresh HijackThis log.


Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process,if asked to restart the computer,please do so immediately.

Thanks,
tea

I installed it and downloaded update but it did't find any infections... What should i do now?
teacup61
Hello,

Look for this file and delete it : C:\WINDOWS\system32\kdtnn.exe, then reboot your computer. Run a full system scan for me with your Kaspersky and tell me what it finds.

Thanks,
tea
