things that i have done:

full scan with: AVG antivirus, spybot S&D, malwarebytes anti-malware, hijackthis (found infected files in sys startup, and i deleted them while sys restore is turned off). tried combofix, but it didnt worked and i always got table that i'm infected with Virut. Managed to download rmvirut.exe from AVG website. 3 times reinstalled windows.

with ubuntu linux live cd destroyed 2 partitions of my hdd and made them into one, then installed windows. this step was last. and now i'm in windows safe mode + network because in normal mode i get BSOD with info that zterbxaghi5.dll has made...........

i dunno what else i can do.

and some info what is happening now:

msconfig shows that in statrtup thereis files:
C:\windows\system32\reader_c.exe
C:\windows\system32\ms18_word.exe
C:\users\pamisheliz\reader_s.exe

and hosts file looks this way:

Hello Pamisheliz

I'm afraid I have very bad news.

Virut is a polymorphic file infector with IRCBot functionality which infects .exe, .scr files, downloads more malicious files to your system, and opens a back door that compromises your computer. 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). Virux is an even more complex file infector which can embed an iframe into the body of web-related files and infect script files (.php, .asp, and .html). 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 infection 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/VirutThis kind of infection is often contracted and spread 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.

If your computer was used for online banking, has credit card information or other sensitive data on it, you should disconnect from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. You should change each password using a clean computer and not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:There is no guarantee this infection can be completely removed. In some instances it may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, 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:Edit: I just noted that you alread received a similar reply in your other thread here. Please do not start new threads or duplicate topics as this causes confusion and makes it more difficult to get the help you need to resolve your issues. I have closed that thread.

Thanks for your cooperation.

i have one last solution to get rid of this virus. i will look in my CD library Hiren's Boot CD, which has bunch of usefull programs. and will use program to format master boot record. i think that Virut "lives" there.

btw.... the funny part of this situation is: of nothing else to do (i was bored, dont want to browse internet, no play game.... anything) in my head "born an idea", to download a virus.
now i REALLY have what to do O_0

i pray if any moderator will see the renew of this new post in this thread :thumbsup:

after yesterday i did following things with my system:
first some "facts", my pc uses 2 HDD one is 120GB(2 partitions: 20gb for windows, whats left for any data) and the second hdd is 320gb for any data and its allinone (no partitions).
so, what i did. from under UBUNTU os i deleted all partitions of 120gb disk, deleted MBR, and after restart inserted winxp dvd, the result in win instalation was 120gb disk is unalocated. after install, i instaled drivers, and at the moment of installing some software from 320gb i got warning from my AVG that i'm infected with virut o.O......
next steps was >>> RESET > insert ubuntu ultimate > insall,configure,etc. and from here i opened kaspersky online scanner. and now i have the LOG what kaspersky did. i will not post or attach it now. i will await of someones response. and will follow orders.

and i think maybe it's better to do everything from under ubuntu. but if you say i will login to windows.
i configured to run properly program WINE, which emulates windows files (fat, ntfs...)

thanks...

If AVG indicates you are still infected with virut, then you probably did something wrong in the process. You need to do a reformat and clean install of the OS.

If you're not sure how to reformat or need help with reformatting, please review:These links include step-by-step instructions with screenshots:Vista users can refer to these instructions:Don't forget you will have to go to Microsoft Update and apply all Windows security patches after reformatting.

Note: If you're using an IBM, Sony, HP, Compaq or Dell machine, you may not have an original XP CD Disk. By policy Microsoft no longer allows OEM manufactures to include the original Windows XP CD-ROM on computers sold with Windows preinstalled. Instead, most computers manufactured and sold by OEM vendors come with a vendor-specific Recovery Disk or Recovery Partition for performing a clean "factory restore" that will reformat your hard drive, remove all data and restore the computer to the state it was in when you first purchased it. See Technology Advisory Recovery Media. If the recovery partition has become infected, you will need to contact the manufacturer, explain what happened and ask them to send full recovery disks to use instead..

If you need additional assistance with reformatting or partitioning, you can start a new topic in the Windows XP Home and Professional forum.

i was maybe not very correct with describing a problem. hdd with windows is clean. but second disk is with viruses. and after win reinstall everything is fine until i open that second hdd. virus is there but not active until i open any exe. pls tell me how to get rid of it while i haven't accessed the disk. and formatting is not an option, because of ~200gb+ of photos. and acctually burning those photos is very long job.
1dvd disk = 4.35GB, 200gb = 46DVD disks, 1dvd burns 15minutes, 46dvd * 15 = 690min = 11h 30 mins, i use pc ~5hours a day, that means it will take half week to save all data.

...after win reinstall everything is fine until i open that second hdd. virus is there

Then that drive needs to be reformatted too or you are only going to infect the primary again.

If you insist on trying to fix this infection instead of following our advice to reformat all hard drives and reinstall your operating system, there are various rescue disks available from major anti-virus vendors which you can try. Keep in mind, even the vendors like Kaspersky say there is no quarantee that some files will not get corrupted during the disinfection process.

Bleeping Computer DOES NOT assume any responsibility for your attempt to repair this infection using any of the following tools. You do this at your own risk and against our advice.

These are links to Anti-virus vendors that offer free LiveCD or Rescue CD utilities that are used to boot from for repair of unbootable and damaged systems, rescue data, scan the system for virus infections. Burn it as an image to a disk to get a bootable CD. All (except Avira) are in the ISO Image file format. Avira uses an EXE that has built-in CD burning capability.If you are not sure how to burn an image, please read How to write a CD/DVD image or ISO. If you need a FREE utility to burn the ISO image, download and use ImgBurn.

Note: In order to use a rescue disk, the boot order must be set to start from the CD-ROM drive. If the CD is not first in the boot order, the computer will attempt to start normally by booting from the hard drive. The boot order is a setting found in the computer’s BIOS which runs when it is first powered on. This setting controls the order that the BIOS uses to look for a boot device from which to load the operating system. The default will normally be A:, C:, CD-ROM. Different computers have different ways to enter the BIOS. If you're not sure how to do this, refer to:If you are considering backing up data, keep in mind, with a Virut infection, there is always a chance of backed up data reinfecting your system. If the data is that important to you, then you can try to salvage some of it but there is no guarantee so be forewarned that you may have to start over again afterwards if reinfected by attempting to recover your data. Only back up your important documents, personal data files, photos to a CD or DVD drive, not a flash drive or external hard drive as they may become compromised in the process. The safest practice is not to backup any executable files (*.exe), screensavers (*.scr), autorun (.ini) or script files (.php, .asp, and .html) files because they may be infected by malware. Avoid backing up compressed files (.zip, .cab, .rar) that have executable files inside them as some types of malware can penetrate and infect .exe files within compressed files too. Other types of malware may even disguise itself by adding and hiding its extension to the existing extension of file(s) so be sure you look closely at the full file name. After reformatting, scan the backed up data with your anti-virus prior to to copying it back to your hard drive.
