About 3 weeks ago the computer was infiltrated by Antivirus Pro 2010. First I ran Norton 360 2.5 to remove and then also followed the manual removal instructions on the Symantec website. The computer continued to direct all web search links to fake virus removal sites. I then downloaded Norton 360 3.0 and installed. Attempts to clean would remove Backdoor.Tidserv (never any of the trails indicated in the Symantec website) and Packed.Generic.233 no matter how many times I would scan, even back-to-back. I contacted Symantec who was happy to have me pay them to clean the computer that their product was incapable of preventing and removing. I was ready to wipe clean and start fresh but kept plugging away and ran across this site and combofix.

I completely remove Norton because combofix indicated it was still running even when I had followed the Symantec instructions for deactivation. This yielded the "blue screen". Running combofix in safe mode wiped Antivirus 2010 and some other malware and also repaired whatever was causing the "blue screen". I reinstalled Norton 360 and it found malware (even after combofix). Initial scans were for ~130,000 files, which is pretty much what a Windows Explore Properties count shows. Norton even found malware during normal operations and popped up a window saying so. I thought all was good. Recent scans though are for ~400,000 files (Explore continues to show only 130,000). This seems odd. Scans continue to show virus activity (today was Backdoor.Tidserv!gen). Norton 360 background detections and scans in the last week or so show multiple entries for antifishing definitions, firewall rules updates (that I haven't asked for), a couple of unauthorized access blocked (send terminate message to window) comments, Packed.Generic.233(twice),Trojan.Dropper, "Trojan Horse", Backdoor.Tidserv!gen, there is always exactly 1 tracking cookie, and various temp files are fixed each scan.

I also find it odd that Norton 360 indicates that the virus definitions updates are always no older than 30 minutes or so. This seems odd. I wasn't aware that Norton auto updated continuously. I thought I had to run LiveUpdate.

Anyway, it appears something is buried somewhere. I would greatly appreciate some help with the current situation and then a recommendation on Antivirus protection seeing as how Norton 360 seems pretty worthless.

Thanks.

Hello jgmccc

Backdoor.Tidserv - TDSServ.sys is a nasty rootkit
Rootkits and backdoor Trojans are very dangerous because they use advanced techniques (backdoors) as a means of accessing a computer system that bypasses security mechanisms and steal sensitive information which they send back to the hacker. 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 backdoor Trojans and rootkits as part of an exploit to gain unauthorized access to a computer and take control of it without your knowledge.
please try this http://www.malwarebytes.org/
Some types of malware will disable MBAM (MalwareBytes) and other security tools. If MBAM will not install, try renaming it.

Before saving any of your security programs, rename them first. For example, before you save Malwarebytes', rename it to something like MBblah.exe and then click on Save and save it to your desktop. Same thing after you install it. Before running it, rename the main executable file first
***
Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run..
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:
o Update Malwarebytes' Anti-Malware
o 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.
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. then please post the log back here so we can see what's going on .

Hello D_N_M,

The instructions were very easy to understand and execute. Thank you. Two items were found. I closed the computer and re-scanned to verify nothing came back. I will probably do this daily or something as I have concerns about the permanence of removal with any of these programs. Anyway, here is the log.

Hello these are not tooo serious but we should still run these next.
Next run ATF and SAS:
Note.. SAS doesn't open the registry hives for other user accounts on the system, so scans should be done from each user account.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
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 and exit the program. DO NOT run yet.

Now reboot into Safe Mode: 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 using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

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 or Opera browser click that browser 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
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

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.

Hello Boopme,

I ran the full scan using Malwarebytes first. It found dome other stuff and then I followed your instructions for ATF and SAS (still need to do other accounts with SAS). Full Mawarebytes log and SAS log follow. Is the QOOBOX folder where combofix dumps stuff and if so, can I delete it?

Hello, Yes those are the ComboFix files. Better to remove Combofix now that we're done with it.
Click on your Start Menu, then Run....
Now type combofix /u in the runbox and click OK. Notice the space between the "x" and "/".


When shown the disclaimer, Select "2"
This will remove files/folders assoicated with combofix and uninstall it.

Rerun MBAM to see if it no longer shows TDDS
Rerun MBAM (MalwareBytes) like this:

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

Boopme,

Run, combofix /u yielded the message that Windows can't find it. I may have used Add/Remove programs previously to remove the program, which obviously didn't remove the Qoobox stuff. I am interested in your suggestion on the next step with this.

MBAM was clean.

Ok then it ois gone. You look good here. If there are no other issues here...
Now 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 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.
