Dear bleeping computer.com,

My partners laptop seems to have a very nasty infection, I've tried every anti-virus, malware removal tool I can think of but can't seem to get them to work.

Hello kadzo, what is your ooperating system?

Let's see how this does,
Reboot into Safe Mode with Networking
How to enter safe mode(XP)
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
.


>>>> Download this file and doubleclick on it to run it. Allow the information to be merged

with the registry.

RKill....

Download and Run RKill
  • Please download RKill by Grinler from one of the 4 links

    below and save it to your desktop.

    Link 1
    Link 2
    Link 3
    Link 4

  • Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as

    malicious. Please refer to this page if you are not sure how.
  • Double-click on Rkill on your desktop to run it. (If you are using Windows Vista, please right-click on it and select Run As

    Administrator)

  • A black screen will appear and then disappear. Please do not worry, that is normal. This means that the tool has been successfully executed.
  • If nothing happens or if the tool does not run, please let me know in your next reply

Do not reboot your computer after running rkill as the malware programs will start again. Or if rebooting is required run it again.


If you continue having problems running rkill.com, you can download iExplore.exe or

eXplorer.exe, which are renamed copies of rkill.com, and try them instead.



Next run Superantisypware (SAS):

Download and scan with SUPERAntiSpyware Free for Home Users
  • Double-click

    SUPERAntiSpyware.exe
    and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If

    you encounter any problems while downloading the updates, manually download them from here.

    Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.


    )
  • In the Main Menu, click the Preferences... button.
  • Click the Scanning Control tab.
  • Under Scanner Options make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen.
  • Back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan.
  • Click "Next" to start the scan. Please be patient while it scans your computer.
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes".
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.

    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the

SUPERAntiSpyware Portable Scanner
instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then

double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.

Hello boopme, Thanks for your quick response.

My partners HP laptop is running Windows Vista home basic 32-bit SP2 Intel Celeron M CPU 530 @1.73GHZ 1.0GB RAM.

I rebooted into safe mode with networking, I then downloaded the file and allowed that to merge (which I think it did), but could not get Rkill to work trying everything you suggested. The only thing it did was open a box for less than a second then it disappeared even with renamed copies. I then moved onto (SAS) again it blocked it from starting with all the things you suggested until I tried the portable scanner....which worked, well to a degree, my first scan (after updating) was a full scan. that went great guns, then stopped and disappeared! but it did find some nasties, which I'd noted down .....Adware.hotbar/shopper reports(low risk) 20 of them and Adware.zango/shopping reports 15 of them.

I then tried a custom scan, checking only startup locations, cookies and selected folders, which it performed fine. It completed the scan and found.... Trojan.agent /GEN-TDSS. 1 of them, Adware.tracking cookie. 35 of them. I don't know if I did right but I clicked to remove them which it said it would do on reboot (I haven't rebooted yet will wait for you to tell me). I then tried a third scan only checking the registry box, I let it scan until it had found Hotbar and Zango then I paused the scan, clicking next, clicked to remove which again it said it would on reboot.

I'm using my own laptop at the moment to post this, so I'll go back to the infested laptop and copy the scan log into my next post (hopefully).

Ok. you did well. We need to run these now and review the logs. Let me know how it's running. I look badck later somewhere.

Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.4.0.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.
  • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If TDSSKiller does not run, try renaming it.
  • To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  • Click the Start Scan button.
  • Do not use the computer during the scan
  • If the scan completes with nothing found, click Close to exit.
  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  • Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  • A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  • Copy and paste the contents of that file in your next reply.



Run this File cleaner,TFC by OT
Please download TFC by Old Timer and save it to your desktop.
alternate download link

Save any unsaved work. TFC will close ALL open programs including your browser!
Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.

Finally Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
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.

Thanks, Ok, I was successful with tdss Rootkit, it downloaded fine and the scan showed no infections. I closed that down and downloaded TFC that also downloaded Ok, and after that finished I rebooted only I wasn't sure if I had to reboot in safe mode or not? So I let it start as normal.
After the desktop loaded I got this message.....Windows found a critical problem, you have one minute to save your work. Or something like that! It then it rebooted, so I took it back into safe mode and downloaded MBAM, which again loaded fine, after updating I clicked quick scan. Again after only a few seconds it closed, I tried again but got the old message, Windows cannot access etc. I did a normal reboot in case that was the problem but to no avail! pesky critter :angry:

This laptop belongs to my partner but her 15 year old son has access to it, and it looks like he's filled it with programs like Ares and Limewire (the worst of all MSN!) to name but a few. They all compete with each other to load up!!
As he is getting his own laptop for Christmas (halaula!) She's ask me to get rid of all the unnecessary programs (she mainly uses it to go on the internet or to print something off). So could you help me with that as well as I know some programs aren't always that easy to completely eradicate! (Norton being one of them lol).

Once again thanks for your quick reply kadzo

Hello, this may be a serious rootkit problem...

Windows found a critical problem, you have one minute to save your work. Or something like that! It then it rebooted, so I took it back into safe mode and downloaded MBAM, which again loaded fine, after updating I clicked quick scan. Again after only a few seconds it closed, I tried again but got the old message, Windows cannot access etc.


We should move you to the Malware removal forum and be certain. after it is cleaned there then we can fix those other issues as it could be impossible if the malware wants to coruupt changes. You can also ask to do those there after they've cleared it/

Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

Please ask any needed questions,post logs and Let us know how the PC is running now.

Hi,
I tried MBam again the way you said but as soon as it starts to scan it goes, I'm not sure what that means when you said "we should move you to malware removal forum" , are you passing me over to someone else to help me (Sorry if I'm being a bit dim lol).
The pc is difficult to access at the moment with all the rubbish programs fighting each other, it usually takes anywhere from ten to fifteen minutes just to boot up. The only way I could tell there was malware on the PC was that AVG wouldn't work, I tried installing Avast but that crashed as well. It does fell slightly quicker when FireFox loads though. At the moment there is no Antivirus program working at all, windows firewall is on though! oh and the windows up date has reappeared after on the last reboot I updated. K

There's definitely something wrong with windows update! I've updated 3 times now and it's reappeared again for the forth time.

Oh and on my post it says moved, I was wondering where to and what's the easiest way to check my thread? K

Hi, yes we are going to need stronger tools and some different assistance. We will need a DDS log to be analyzed by another member of our staff. They will determine how to remove what is hidden that we cannot see.

BTW ,I do not see any "Moved " marking.

We need a deeper look. Please go here....
Preparation Guide .

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If Gmer won't run,skip it and move on.
Let me know if that went well.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic363071.html you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :cherry:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
