Virus/malware issue

Hi, this is my cousin's computer. I don't know what symptoms it's showing except that when you turn it on, it throws error messages such as:

The application or DLL C:\ windows/system32/sehaniju.dll is not a valid Windows image. Please check this against your installation diskette.

These pop-up error messages don't go away and continue to interrupt any activity. The computer will not open anything from the desktop such as IE or AVG. It WILL boot into safe mode and the messages go away. The only other thing I can add is that I can tell from the desktop that she's running an outdated verison of AVG (7.5). Thank you in advance for any help you can provide.

Welcome to Safer Networking, I wish to be sure you have viewed and understand this information.

All advice given is taken at your own risk.
Please make sure you have read this information so we are on the same page.

Pinned (sticky) to the top of this forum, and posted above are the directions, make sure you have read and followed them.

C:\ windows/system32/sehaniju.dll <<< see the Google:
http://www.google.com/search?hl=en&q=sehaniju.dll+&btnG=Search

The computer is infected and the junk can be hard to remove. If you want to give it a try, read the "Before you Post" directions so you will know what is expected of you. Let's see if we can get a HijackThis for a first look, using a self-installer.

Let's wait until the junk is gone to update the antivirus program.

Download Trend Micro Hijack This™ to your Desktop
http://download.bleepingcomputer.com/hijackthis/HJTInstall.exe
Doubleclick the HJTInstall.exe to start it.
By default it will install HijackThis in the Program Files\Trendmicro folder and create a desktop shortcut.
HijackThis will open after install. Press the Scan button below.
This will start the scan and open a log.
Copy and paste the contents of the log in your next reply.

Post also an uninstall list if possible: Open Hijackthis.
Click the "Open the Misc Tools" section Button.
Click the "Open Uninstall Manager" Button.
Click the "Save list..." Button.
Save it to your desktop. Copy and paste the contents into your reply.

Hi, and thanks in advance for the effort to help. I read the Before You Post thread, but the problem is that I cannot access the internet from this computer. Attempts to open IE or Firefox (she has both on her desktop, I'm not sure which she uses) are unsuccessful. Should I attempt to download open and download HJT from safe mode?

From "Before you Post"

Note: If you have lost your Internet connection on the infected computer, or otherwise cannot post from that machine; you can download HJT to a clean PC if one is available. You can also try this if malware is blocking your access to security forums and tools.

Oh I'm sorry, I must've missed that, my apologies. How would I go about doing this? Forgive my ignorance, but how would I transfer HJT from one PC to another?

I apologize, when you indicated you were trying to help the cousin, I assumed you had computer knowledge. Doing remote repairs are tough enough without the computer being unable to access the online tools we use, bringing a third computer into the mix makes it that much harder. You may want to first consider if this is something you want to do and if you have the knowledge to do this.

HijackThis is just the first diagnostic tool we will need, if you can not download them on the infected computer, then you would need to download them to a Flash drive, USB device or CD on a computer not infected and bring them to the infected computer.

http://www.ehow.com/how_2019960_transfer-files-flashdrive.html
http://www.everythingusb.com/hardware/Storage/USB_Flash_Drives.htm

If both computers have a floopy drive, it can be used, but floppy disk space is limited to around 1.4 MB's and combofix which we will likely need, is 2.92 MB's.

If you have the ability to burn the information to a CD, you can bring the download to the infected computer in that way.

Hope that helps

I do have some computer knowledge, but for some reason was drawing a blank on how to transfer a program from one computer to another. I'll download it to a CD and load it that way, then report back. Thank you again.

Well.. this machine is in bad shape. I downloaded HJT onto a disk from a clean computer and attempted to load it onto the infected one. I was able to open the disk drive and drag HJT onto the desktop, but was unable to actually open the program. Double-clicking and right click open do not open the program. The hourglass temporarily comes up, but the program never opens and it's as if I never tried to do it. I tried to open/run it in safe mode, but here I can't even get the disk drive to open. Thanks in advance for any help...

Possible the malware is blocking common tools? Try renaming HJT before you download it to something like: Morgan18.exe
For instance, click the link: choose "Save this file now" then click OK.
Make sure you save it where you wish but change the name to Morgan18.exe, then save it. Now bring that to the infected computer and see if it will run.

Have you considered a reformat?

With badly infected computer like this, it can be the right decision.

Thanks

OK, I renamed it and was able to open it in safe mode. Here is the log from the scan as well as the uninstall list (which turned up a version of Limewire, surprise surprise):

Sorry to have to be the bearer of bad news, this is a very infected computer. This is the bad one, which is a file infector called Win32/Virut.

This machine needs to be formatted.

This system is infected with a polymorphic file infector called Virut. Virut is capable of infecting all the machine's executable files (.exe) and screensaver files (.scr). However, the problem is that the virus has a number of bugs in its code, and as a result, it may misinfect a proportion of executable files and therefore, the files are corrupted beyond repair. As of now, security experts suggest that a format and clean install, or destructive recovery if you have an OEM recovery partition, is the best way to clean the infection and it is the best and safest way to return the machine to its normal working state.

Backup all your documents and important items (personal data, work documents, etc) only. DO NOT backup any executable files (softwares) and screensavers (*.scr). It attempts to infect any accessed .exe or .scr files by appending itself to the executable.

Also, avoid backing up compressed files (zip/cab/rar) files that have .exe or .scr files inside them. Virut can penetrate and infect .exe files inside compressed files too.

Recent variants also modify htm, html, asp and php files.

Do not back up to another machine, as it may become compromised. Burn to DVD/CD, or to an external drive which has nothing else on it, and which you can format should it happen to become infected from the backups.

Alright, thank you for the help and advice. I ended up using a 4GB USB drive that I use to back up important files on my own computer, to transfer stuff back and forth. I deleted everything from it and it's now empty, but is it infected with anything after being in contact with the infected machine?

My advice would be to format it also to be safe, you don't want Virut on the uninfected computer.

Great, thanks. I just reformatted the USB. Now I have to call my cousin to break the news and see if she has all the disks that came with her computer. Thank you very much for the help, I was referred to this forum for this problem and I was not dissapointed, thanks again.

One more thing... as I'm scanning through this computer, it looks like the only thing's shes going to want are her music, pictures, and homework related stuff (she's 15). There's no way a music or picture file could be infected, right? That stuff is all safe to backup and reload after the computer is fresh again?
