I have a Dell Inspiron 531S computer. The OS is Vista 32-bit. Processor is AMD Athlon 64 X2 Dual Core 5000+ 2.6 GHz, 3.0 GB of RAM.

This computer was infected about a month ago. After the anti-virus software I had installed couldn't get rid of it I did visit another forum for help. They guy helping me decided that Windows and IE were corrupted and it wouldn't let me download, install, or run any of the programs he suggested. He gave me a link to a program with vague instructions to burn it to a disc and reboot the computer from the CD-ROM drive.

To do this I used my wife's laptop, which is a fairly old and outdated IBM ThinkPad. It has Windows XP Professional version 2002, 1.73 GHz processor, and 2.0 GB of RAM. After several tries I couldn't get the other computer to boot from the CD-ROM. The person helping me in that forum stopped responding, so I gave up and put that computer aside.

Yesterday I decided to just try and reboot it using the Dell disc that came with it, but before I did that I wanted to save the documents, pictures, and videos I have saved on that hard drive. I saved them to several DVD-R discs and everything seemed to be going fine. But when I placed one of the discs in the laptop to make sure it saved right, it acted like a blank disc. I put the disc back in the Dell computer to see if the files showed up there, and again I got the window that popped up treating it as if it were a blank disc, asking if I wanted to format it to save files.

So if possible, I would like to try and save the files from the infected Dell before I try to remove the virus or just throw the computer in the trash. Thanks

Welcome to the forum.


Caution: If you are considering backing up data and reformatting, 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, .htm, .html, .xml ) files because they may be infected by malware. Avoid backing up compressed files

(.zip, .cab, .rar) that have executables inside them as some types of malware can penetrate compressed files and infect the .exe files within them. Other types of malware may

even disguise itself by hiding a file extension or adding to the existing extension as shown

here (click Figure 1 to enlarge) so be sure you look closely at the full file name. If

you cannot see the file extension, you may need to reconfigure Windows to show file name extensions

. Then make sure you scan the backed up data with your anti-virus prior to to copying it back to your hard drive.

If your CD/DVD drive is unusable, another word of caution if you are considering backing up to an external usb hard drive as your only alternative. External drives are

more susceptible to infection
and can become compromised in the process of backing up data
. I'm not saying you should not try using such devices but I want to make you

aware of all your options and associated risks so you can make an informed decision if its worth that risk.Again, do not back up any files with the following file extensions: exe, .scr, .ini, .htm, .html, .php, .asp, .xml, .zip, .rar, .cab as they may be infected.

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

Operating Systems Subforums forum
.

Thank you. Is there a way you can tell me how bad my Dell is infected, and IF it is possible to get rid of the infection without reformatting?

Thanks. I have internet ut I took the infected computer offline. It was redirecting every page I tried to open and wouldn't let me download anything anyway and I wanted to make sure it didn't infect my router. I'll try to burn the CD from my laptop and see if that works. The CD-ROM drive in the infected computer does work. I was able to burn videos to a DVD using the Windows DVD Maker. When I tried to write files to a blank DVD as data files, I couldn't read them on my laptop. I'm not sure if the prolem was caused by the infected computer not writing them correctly or the laptop not reading them correctly. As I said earlier, I was given a link to a program on another forum to burn to a CD and instructions how to burn the image to the CD and boot the infected computer from the CD-ROM drive. It didn't work, and I wasn't sure if it was because my laptop didn't burn the image correctly or if the virus is not allowing the other computer to be booted from the CD-ROM drive. Apparently the guy that was helping me on that forum didn't know either because he just stopped responding to the thread. That was a month ago. I got frustrated and left the computer alone, but I'm willing to try anything because there's a lot of info I need off the infected computer - if it's possile to retrieve it. If I can get it up and running again - even better.

You can also try to Reboot into Safe Mode with Networking,this may bypass the malware.
How to start Windows 7 in Safe Mode

<<><<><><><><><><><><><><><><><><><><><><><>
Reboot into Safe Mode with Networking
How to enter safe mode(XP/Vista)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode with Networking using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.


Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1 <<<== Use this one first.

Download Link 2MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

I downloaded the Avira Rescue Program and burned it to a CD. I booted the infected computer with the CD. All that has happened so far is a black screen with the cursor flashing in the top left corner. Is that what should be happening? It's been that way for 10 minutes so far.

I let it go for almost an hour, and tried restarting it a couple times. All it does is go to the blank screen with the cursor flashing. I noticed in the tutorial there's supposed to e a menu that comes up. I tried safe mode when I was messing with it a month ago. When I tried to do certain things I'd get a window popping up telling me I don't have access or permission to perform that action. When I tried to run scans from Windows the scan would start and shut down immediately. That's why the last guy told me I needed to run a scan from a CD boot.
