I have been checking others and it sounds like I have a similar UAC rootkit. Kind of confused on the steps and I dont want to do something out of step.

XP - sp3.
visited a site in ff3.5 and then a "windows security center" pops up wanting to install a trial version because it detected trojans/viruses. a
I checked the real security center and it said the service was disabled. I could not re-enable the service. It tried to uninstall avg 8.5 too.

I restarted, tried safe mode - blue screen
I restarted to restore under last best config - still got the face security window. AVg found a file under windows/system32/UACyypjijaioawohbxvu.dll

I grabbed all of them and avg has quarantined them.

Then I found this site with that uac...dll.

I have been able to disable the program from harassing me but avg still pops up finding the uac dlls every few minutes.

Thanks in advanced!

Please download RootRepeal Rootkit Detector and save it to your Desktop.

* Close all programs and temporarily disable your anti-virus, Firewall and any anti-malware real-time protection before performing a scan.
* Click this link to see a list of such programs and how to disable them.
* Create a new folder on your hard drive called RootRepeal (C:\RootRepeal) and extract (unzip) RootRepeal.zip. (click here if you're not sure how to do this. Vista users refer to this link.)
* Open the folder and double-click on RootRepeal.exe to launch it. If using Vista, right-click and Run as Administrator...
* Click on the Files tab, then click the Scan button.
* In the Select Drives, dialog Please select drives to scan: select all drives showing, then click OK.
* When the scan has completed, a list of files will be generated in the RootRepeal window.
* Click on the Save Report button and save it as rootrepeal.txt to your desktop or the same location where you ran the tool from.
* Open rootrepeal.txt in Notepad and copy/paste its contents in your next reply.
* Exit RootRepeal and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.

Note: If RootRepeal cannot complete a scan and results in a crash report, try repeating the scan in "Safe Mode".

Please download Malwarebytes Anti-Malware 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.

When I try and run in safe mode, it sticks on sptd.sys and then blue screens still.

I am running these steps in admin, will that work?

I'm not sure why it would blue screen.

By "Admin" I assume you mean the Admin account but in Normal Mode.

Post the log when it's finished.

I think blue screen is from a previous issue with my system.

And yes, admin, but in normal mode is what I am running this in.

I have to go to bed so I will let you know about the logs in the morning.

Just so you know, I have never found such an amazing resource as this place! I will be praising your names forever, thanks for helping on this.

If you’re clean, you should create a new Restore Point to prevent possible re-infection from an old one.

Go 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 Restore Point a name and then click Create. Then use Disk Cleanup to remove all but the most recently created Restore Point. Go Start > Run and type: "Cleanmgr" (without the quotes). Click Ok > More Options tab > Clean Up in the System Restore section to remove all previous restore points except the newly created one.

Also, go Start > Control Panel and double-click Add or Remove Programs. Post back and report any Java entries that you have.
