Hi everyone,

For the past week I've been dealing with several viruses and Trojan horses that I got from an infected DOK. I used to have Windows xp Home edition (sp3) but during the crash I reinstalled the SP1 edition. my problems are as followed:

Every time I delete the files (using various software), it keeps coming back while connecting to the web, the files are mostly these:

ndisio.sys
reader_s.exe
services.exe (windows directory(

When I'm trying to reinstall the services pack, I get an error claming that ndis.sys is in use and the installation can't go on.

My main problem is that I don't want to format the disk as I have valuable files that weren't backup. When trying to use Nero and some other media apps such as QuickTime and windows media player the program crashes (I think it has to do with a corrupted direct x).

I would love to provide you with further details as I'm rally frustrated with the whole situation.

Also while browsing in Google. I keep getting redirected into porn sites.

Thanks in advance,

Oren.

Hello first I am moving this from the XP to Am I Infected forum to remove malware. you will eventually neeed to get SP2 and even 3 later to protect from exploits.

So let's sart with these.
Go into Control Panel>Add Remove Programs. Be sure the 'Show Updates' box is checked. Go down the list and tell me what Java applications are installed and their version. (Highlight the program to see this).

Next run ATF:
Please download ATF Cleaner by Atribune & save it to your desktop.
  • Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".


Next run MBAM:
Please download Malwarebytes Anti-Malware (v1.32) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • 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 updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
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 and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM 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 after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

Hi, thanks for the reply.

Well I managed to install sp3 (without sp2), the computer is more stable now, however the virus appears when connecting to net, it's not working/spreading when the internet is disconnected.

Thanks.

Well here is the thing,

While disconnected it showed nothing (after a cleanup),

following a connection is basically loads up some *.tmp files (bn1.tmp for example).

afterward it download/spreads reader_s.exe and services.exe (while using cmd and netsh commands to disable to firewall), it also add up files as ccevtsvc.exe

I'm really frustrated as I've been dealing with this for almost 2 weeks and I need this computer in order to work (I'm a videogames journalist).

Thanks.
