Hi there,
my name is Marius and I will assist you with your malware related problems.

Before we move on, please read the following points carefully.

  • First, read my instructions completely. If there is anything that you do not understand kindly ask before proceeding.
  • Perform everything in the correct order. Sometimes one step requires the previous one.
  • If you have any problems while following my instructions, Stop there and tell me the exact nature of your problem.
  • Do not run any other scans without instruction or add/remove software unless I tell you to do so. This would change the output of our tools and could be confusing for me.
  • Post all logfiles as a reply rather than as an attachment unless I specifically ask you. If you can not post all logfiles in one reply, feel free to use more posts.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.
  • Stay with me. I will give you some advice about prevention after the cleanup process. Absence of symptoms does not always mean the computer is clean.
  • My first language is not english. So please do not use slang or idioms. It could be hard for me to read. Thanks for your understanding.

 

 

 

Going over your logs I noticed that you have µTorrent installed.

  • Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs.
  • They are a security risk which can make your computer susceptible to a wide variety of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites.
  • Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users.
  • The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications.

It is pretty much certain that if you continue to use P2P programs, you will get infected again.
I would recommend that you uninstall µTorrent, however that choice is up to you. If you choose to remove these programs, you can do so via Start > Control Panel > Add/Remove Programs.
If you wish to keep it, please do not use it until your computer is cleaned.

 

 

 

 

Scan with TDSS-Killer

Please read and follow these instructions carefully. We do not want it to fix anything yet (if found), we need to see a report first.

Download TDSSKiller.zip and extract to your desktop

  • Execute TDSSKiller.exe by doubleclicking on it.
  • Press Start Scan
  • If Malicious objects are found, do NOT select Copy to quarantine. Change the action to Skip, and save the log.
  • Once complete, a log will be produced at the root drive which is typically C:\ ,for example, C:\TDSSKiller.<version_date_time>log.txt


Please post the contents of that log in your next reply.

Combofix

Download ComboFix from one of these locations:

Link 1
Link 2


* IMPORTANT- Save ComboFix.exe to your Desktop

====================================================


Disable your AntiVirus and AntiSpyware applications as they will interfere with our tools and the removal. If you are unsure how to do this, please refer to our sticky topic How to disable your security applications


====================================================


Double click on ComboFix.exe & follow the prompts.

  • As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it's strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.

**Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.


RC_update.png


Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:


cfRC_screen_2.png


Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply for further review.

Hey I downloaded combofix but after extracting the files it says that "Combo Fix files are compromised. Please obtain a fresh copy. You may have a virus "viruit" (or something like that) so what should I do now?

uh oh...

 

 

Create/Scan with Kaspersky Rescue Disk

Follow the instructions on this page for downloading the kav_rescue_10.iso (200 mb) file and creating the Kaspersky Rescue Disk.

Make sure you set to boot the machine from the CDRom drive first. Then save and exit the BIOS. The computer will begin to boot. Insert the disc in the CDrom drive, then restart the machine. It should then boot from that CD.

It's best if you refer to the instructions and images at Kaspersky How to record Kaspersky Rescue Disk 10 to a CD/DVD and boot my computer from the disk?

Once it boots from CD, press a key so it continues to boot from that CD.

Select the language, then be sure to select Kaspersky Rescue Disk Graphic Mode.

Kaspersky should begin scanning your machine. If it finds infection, look carefully at the files it lists. If any of them seem to be legit files, do not allow it to clean/quarantine/delete them. Rather, save the log and post the results for me to look over.

Uh... Hey man my current internet speed is about 2-15 kb/s due to all these viruses. So it will take me a LONG time to download 200MB. So do I have a alternative option or do I have to download it?

I would strongly recommend to download and run this CD.

If you have someone nearby with another computer, perhaps this person may download and burn the image for you.

I'm afraid I have very bad news. Your system is infected with a nasty variant of Virut, a dangerous polymorphic file infector with IRCBot functionality which infects .exe, .scr files, and opens a back door that compromises your computer. Using this backdoor, a remote attacker can access and instruct the infected computer to download and execute more malicious files. -- Note: As with most malware infections, the threat name may be different depending on the anti-virus or anti-malware program which detected it. Each security vendor uses their own naming conventions to identify various types of malware.

With this particular infection, the safest solution and only sure way to remove it effectively is to reformat and reinstall the OS. Why? According to this Norman White Paper Assessment of W32/Virut, some variants can infect the HOSTS file and block access to security related web sites. Other variants of virut can even penetrate and infect .exe files within compressed files (.zip, .cab, rar). The Virux and Win32/Virut.17408 variants are an even more complex file infectors which can embed an iframe into the body of web-related files and infect script files (.php, .asp, .htm, .html, .xml). When Virut creates infected files, it also creates non-functional files that are corrupted beyond repair and in some instances can disable Windows File Protection. In many cases the infected files cannot be disinfected properly by your anti-virus. When disinfection is attempted, the files become corrupted and the system may become irreparable. The longer virut remains on a computer, the more critical system files will become infected and corrupt so the degree of damage can vary.

The virus disables Windows File Protection by injecting code into the "winlogon.exe" process that patches system code in memory.
CA Virus detail of W32/Virut

The virus has a number of bugs in its code, and as a result it may misinfect a proportion of executable files....some W32/Virut.h infections are corrupted beyond repair.
McAfee Risk Assessment and Overview of W32/Virut

There are bugs in the viral code. When the virus produces infected files, it also creates non-functional files that also contain the virus...Due to the damaged caused to files by virut it's possible to find repaired but corrupted files. They became corrupted by the incorrect writing of the viral code during the process of infection. undetected, corrupted files (possibly still containing part of the viral code) can also be found. this is caused by incorrectly written and non-function viral code present in these files.
AVG Overview of W32/Virut Virut is commonly spread via a flash drive (usb, pen, thumb, jump) infection using RUNDLL32.EXE and other malicious files. It is often contracted by visiting remote, crack and keygen sites. These type of sites are infested with a smörgåsbord of malware and a major source of system infection.

...warez and crack web pages are being used by cybercriminals as download sites for malware related to VIRUT and VIRUX. Searches for serial numbers, cracks, and even antivirus products like Trend Micro yield malcodes that come in the form of executables or self-extracting files...quick links in these sites also lead to malicious files. Ads and banners are also infection vectors...
Keygen and Crack Sites Distribute VIRUX and FakeAV However, the CA Security Advisor Research Blog have found MySpace user pages carrying the malicious Virut URL. Either way you can end up with a computer system so badly damaged that recovery is not possible and it cannot be repaired. When that happens there is nothing you can do besides reformatting and reinstalling the OS. Since virut is not effectively disinfectable, your best option is to perform a full reformat as there is no guarantee this infection can be completely removed. In most instances it may have caused so much damage to your system files that it cannot be completely cleaned or repaired. In many cases the infected files (which could number in the thousands) cannot be deleted and anti-malware scanners cannot disinfect them properly. Security vendors that claim to be able to remove file infectors cannot guarantee that all traces of it will be removed as they may not find all the remnants. If something goes awry during the malware removal process there is always a risk the computer may become unstable or unbootable and you could loose access to all your data. Further, your machine has likely been compromised by the backdoor Trojan and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume the computer is secure even if your anti-virus reports that the malware appears to have been removed. Many experts in the security community believe that once infected with this type of malware, the best course of action is to reformat and reinstall the OS. Reinstalling Windows without first wiping the entire hard drive with a repartition and/or format will not remove the infection. The reinstall will only overwrite the Windows files. Any malware on the system will still be there afterwards. Please read:

Whenever a system has been compromised by a backdoor payload, it is impossible to know if or how much the backdoor has been used to affect your system...There are only a few ways to return a compromised system to a confident security configuration. These include: • Reimaging the system • Restoring the entire system using a full system backup from before the backdoor infection • Reformatting and reinstalling the system
Backdoors and What They Mean to You This is what security expert miekiemoes has to say: Virut and other File infectors - Throwing in the Towel?

If I guide someone with Virut (or any other File Infector) present and their Antivirus cannot properly disinfect it, then I recommend a format and reinstall...dealing with such infections is a waste of time and that's why I prefer the fastest and safest solution - which is a format and reinstall...After all, I think it would be irresponsible to let the malware "stew" (download/spread/run more malware) for another couple of days/weeks if you already know it's a lost case.
This is what Jesper M. Johansson at Microsoft TechNet has to say: Help: I Got Hacked. Now What Do I Do?.

The only way to clean a compromised system is to flatten and rebuild. That’s right. If you have a system that has been completely compromised, the only thing you can do is to flatten the system (reformat the system disk) and rebuild it from scratch (reinstall Windows and your applications).
