I'm paranoid that I may be infected

My bank contacted me late last week stating that someone had tried to establish a wire transfer in my account (twice!). I've had to close my account. The bank's fraud department suggested that I may have some type of keylogger on my PC. For more than a year, I have been running Spybot S&D resident, BitDefender, Crapcleaner, and Window Washer, as well as Microsoft's Firewall protection. I've only had one instance of a Trojan infection about a month ago, and BitDefender cleaned it up. I'm paranoid that there is something still lurking in the system. I've been having trouble with Bitdefender crashing numerous times per day. They offered no support or ideas. So, after the bank incident last week, I uninstalled Bitdefender and went with PCSecurityShield's - Shield Deluxe 2010 (which looks surprisingly exactly like Bitdefender!). I've gone into Safe Mode and run Spybot, Shield Deluxe, and Crap Cleaner. Nothing comes up that indicates an infection. But, I would like a second opinion before I start changing all of my passwords and re-setting up all my online banking, etc. I don't want something or someone grabbing all of my new passwords, etc.

I am now so gun-shy of using any free-ware or online 'free' scanners. Can you suggest any additional checks I can/should make to ensure that my system is "clean"?

Thanks very much.

Please download Malwarebytes Anti-Malware (v1.41) and save it to your desktop.
alternate download link 1
alternate download link 2

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. 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.
  • 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.

Dear Quietman7,

Wow! I can't tell you how upset I am... :thumbsup: .

MBAM picked up 7 'nasties'. Is it that Spybot, BitDefender & PC Sheild are lousy products and can't catch these things? I really worry about the infection that says "stolen data". Ugh! Thanks and let me know what to do next, if you would. I so appreciate your help.

Here's the log from MBAM for your review: Thanks again.... Tom

Is it that Spybot, BitDefender & PC Sheild are lousy products and can't catch these things?

No single product is 100% foolproof and can detect and remove all threats at any given time. The security community is in a constant state of change as new infections appear. Each vendor has its own definition of what constitutes malware and scanning your computer using different criteria will yield different results. The fact that each program has its own definition files means that some malware may be picked up by one that could be missed by another. Thus, a multi-layered defense using several anti-spyware products (including an effective firewall) to supplement your anti-virus combined with common sense and safe surfing habits provides the most complete protection.

NOTE: It is not uncommon for subsequent scanning after updates of a particular security product has been released to result in detection of items which had previously gone undetected by prior scans.

Now rescan again with Malwarebytes Anti-Malware, but this time perform a Full Scan in normal mode and check all items found for removal. Don't forgot to check for database definition updates through the program's interface (preferable method) before scanning and to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

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.
Please download Dr.Web CureIt and save it to your desktop. DO NOT perform a scan yet.
alternate download link
Note: The file will be randomly named (i.e. 5mkuvc4z.exe).

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on the randomly named file to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to download the Full version Free Trial, just ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All. (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • After the Express Scan is finished, put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and uncheck "Heuristic analysis" under the "Scanning" tab, then click Apply, Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • Please be patient as this scan could take a long time to complete.
  • When the scan has finished, a message will be displayed at the bottom indicating if any viruses were found.
  • Click Select All, then choose Cure > Move incurable.
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)
If you cannot boot into safe mode or complete a scan, then try doing it in normal mode. Be aware, this scan could take a long time to complete..

Well, I've followed your instructions.

1. I rescanned with MBAM and it looked clean. The logfile is below.
2. I ran TFC without any problems, and it rebooted fine.
3. I downloaded Dr.Web CureIt. Rebooted and entered Safe Mode. I followed your instructions and it started scanning fine... until about 8 minutes into the scan, then the PC rebooted on its own. So, I rebooted into Safe Mode again and started following the process again. This time a dialog box came up entitled:
twa 33xp with the message: [Virus database]C:\DOCUME~1\Tom\LOCALS~1\Temp\dc57210914\efb06e99 - failed. I repeated this process 2 more times. Per your last comment, I am now going to perform the scan under normal boot mode. I'll let you know what happened.

Thanks again and here's the log from the latest MBAM:

I decided to do a fresh download of Dr.Web and try it in Safe Mode one more time. It worked this time. It couldn't find any viruses. The log file was very large, so I omitted about 430+ pages of stuff and have copied the beginning and the end/statistics of the log below.

Should I be feeling pretty confident now that my system is "clean"?

Thanks again. Tom

How is your computer running now? Are there any more reports/alerts, signs of infection or issues with your browser?

I've not received any further alerts or messages indicating there might be a virus. The PC seems slow, but I'm not positive on that. I'm not sure about the browsers yet. They seem to be acting strange sometimes, but that could be my fault. I had turned off all cookies and used the highest levels of their inherent security settings. That was a bit too restrictive. I am, however, getting the following dialogue box when I open IE. I've been using Firefox because of it. Any thoughts?

The first box shows:

A program on your computer has corrupted your default search provider setting for Internet Explorer.
Internet Explorer has reset this setting to your original search provider, Google (www.google.com).
Internet Explorer will now open Search Settings, where you can change this setting or install more search providers.


Thanks so much for your help on all this stuff. My biggest concern was that someone was stealing my important and private data, and I wouldn't know until the damage had been done.

Hopefully, the system is clean now.

Thanks again.

Tom

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 backed up, renamed and 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 Posted Image > 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 in Vista and Disk Cleanup in Vista.


If you do a search on the net for A program on your computer has corrupted your default search provider setting or Internet Explorer has reset the setting to your original search provider, you will find thousands of similar reports with various causes and possible solutions. What works for one person may not work for another.

These are a few example solutions I found but you may have to search some more if they do not work for you.CAUTION: Some of these steps involve making changes in the registry. Always back up your registry before making any changes. If you are not familiar with working in the registry, then you should NOT attempt to make any changes on your own. Improper changes to the registry could adversely affect your computer and render it inoperable. ERUNT is an excellent free tool that allows you to to take a snapshot (backup) of your registry before making changes and restore it when needed.

Thank you very, very much! Your advice and explanations have been invaluable. And, I've gone out to a number of the tutorials over the last few days and learned a hell of a lot about things that I was unfamiliar with or wrong about (i.e. the Registry tutorial is great).

I am so glad to have found this site, and that you were kind enough to help me out.

Sincerely,

Tom :thumbsup:
