Ok, I'll try to be brief but informative
I am not that computer savvy, but can usually muddle my way through things

I was recently away for vacation and a younger family member (my niece) was house sitting
After returning I noted problems with IE7 - slow initially, and then images would not load
Thunderbird worked fine
FF worked ok for the start up screen but then would go to windowsclick if I clicked a link

I assumed I had a virus/problem
I had Norton 360 running but not with the most recent update (~2 wks ago the subscription had run out and I was contemplating an alternate program)

Then all hell broke loose, An NT Authority screen would splash up and closed my computer, I could not access or run Norton and the browser difficulty made correcting the problem impossible
I was able to download AVG free but could not install it due to "a running Antivirus" program which I presume was a component of Norton 360 still active however I could not seem to access Norton 360 at all.
On researching windowsclick I ran across this site and utilizing the info provided on some threads proceeded to download and run Combofix

Please note I needed my laptop to download the program and needed to change the name to fixcombo to run the program once transferred by usb key to the "infected" computer as almost no programs seemed to function

I then had problems due to the installed Norton 360 when running Combofix but I could not delete Norton 360 either
I basically decided to run the program anyways
It did find a number of files with problems and I have the log available if required

Once combofix was run once I was able to remove Norton 360

I then reran Combofix (log is available on request also) but I'm not sure if further files are of concern

I did install AVG free and run a scan which found a rfsxf . exe trojan which is now vaulted (I believe)

What more do I need to do?
Is there a way to know whether any sensitive information on the computer is compromised?

Any info is greatly appreciated!!!
Also I'm sorry I used Combofix without discussing issue first (as some posts suggest that is inadviseable, but I read that part later)

Hi and welcome to BleepingComputer :thumbsup:

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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.
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.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

Thank you for the quick response
I had run the AVG a second time and picked up a trojan

Then ran the suggested program:

Malwarebytes' Anti-Malware 1.34
Database version: 1825
Windows 5.1.2600 Service Pack 3

I then ran the suggested program a second time with no evidence of infection

Am I safe?
Should I change all my passwords/contact banks etc?

If you cannot boot into safe mode, then perform the above instructions in normal mode.

IMPORTANT NOTE: One or more of the identified infections was related to a nasty variant of the TDSSSERV rootkit component. Rootkits, backdoor Trojans, Botnets, and IRCBots are very dangerous because they compromise system integrity by making changes that allow it to by used by the attacker for malicious purposes. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. Remote attackers use backdoors as a means of accessing and taking control of a computer that bypasses security mechanisms. This type of exploit allows them to steal sensitive information like passwords, personal and financial data which is send back to the hacker. To learn more about these types of infections, you can refer to:If your computer was used for online banking, has credit card information or other sensitive data on it, 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. They should be changed 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 again. and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:Although the rootkit was identified and removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume that because this malware has been removed the computer is now secure. In some instances an infection 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. Please read:

Anything further?
And I see what you are commenting about the safety of my computer/reformat but will I also need to do my storage drive?
Are photos/movies etc safe there or do they need transfer to a disc etc or are they potentially a risk?
I'm assuming not but would greatly appreciate your opinion

Your decision as to what action to take should be made by reading and asking yourself the questions presented in the "When should I re-format?" and What Do I Do? links I previously provided. As I already said, in some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. Wiping your drive, reformatting, and performing a clean install of the OS or doing a factory restore with a vendor-specific Recovery Disk or Recovery Partition removes everything and is the safest action but I cannot make that decision for you.

Reformatting a hard disk deletes all data. Should you decide to reformat, you can back up all your important documents, personal data files and photos. 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. Some 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, as a precaution, make sure you scan these files with your anti-virus prior to copying them back to your hard drive.

If you're not sure how to reformat or need help with reformattng, please review:These links include step-by-step instructions with screenshots:Don't forget you will have to go to Microsoft Update and apply all Windows security patches after reformatting.
Also see How to keep your Windows XP activation after clean install.

Note: If you'rer 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 you're not going to reformat and if there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.
