Working on a customers machine yesterday Sept 20, 2007 running Hijack this I spotted a Appinit.dll which is __C00B1C12.dat

It can not be deleted. It is in the windows\system32 area.

It also is in the registry as well.

TrendMicro online scanner picked it as malware..

AdAware did not
Avast did not
Mcafee did not

Everything I tried from the normal standpoint.. Vundofix.. McAfee Stinger.. have not touched it.

Right mouse clicking on the dat file shows that it was created Sept, 10th. 2007

I suspect the customer got it via myspace or limewire.

I have not found a thing on line referring to this specific file.

I do not have a log to post as I will not be at that machine until sometime next week again.

I believe it is the reason broadcaster.com pop ups are happening in IE and in Firefox browsers

Any assistance if some one has encountered this.. would be tremendous

Thanks

Jim

Go to jotti's virusscan or virustotal.com. In the "File to upload & scan" box, browse to the location of the suspicious file and submit (upload) it for scanning/analysis.
Post back with the results of the file analysis.

I am hoping to have access to that computer again on Tuesday Sept 25, 2007.. If I can upload the file I will. Beacuse as soon as one opens a browser.. continous browsers popup one after the other after the other.

It makes it a bit hard to work that way. but I will give it a whirl

thanks

Jim

ATTENTION: VirusTotal is a free service offered by Hispasec Sistemas. There are no guarantees about the availability and continuity of this service. Although the detection rate afforded by the use of multiple antivirus engines is far superior to that offered by just one product, these results DO NOT guarantee the harmlessness of a file. Currently, there is not any solution that offers a 100% effectiveness rate for detecting viruses and malware.

As you can see some of the Anti-virus scanners did not pick this up. They have McAfee and I put on Avast.. After this report I put on AVG and that deleted the file.

Thanks for the tip. It also seems to of stopped all the broadcaster.com popups.. I kind of thought that file had something to do with them.

Thanks again,
Jim

Definitely not a good file. But where there is one, there usually is more. Even though the pop ups have stopped, lets check a bit further.

Please download ATF Cleaner by Atribune & save it to your desktop. DO NOT use yet.

Please download and install SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.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 and unzip into the program's folder.)
  • Under "General and Startup", make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Under "Configuration and Preferences", 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 and exit the program.
  • Do not run a scan just yet.
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".

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 browser click Firefox 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.
  • If you use Opera browser click Opera 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.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and 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 and click "Next".
  • 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" 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. 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.
