I have read that several people also have trojan horse agent.AABY and trojan horse agent.AACL like I do. Is there a straight forward solution?

There is AVG 8.0 free, SpyBot Search and Destroy, and Mawarebytes on my computer up to date and are getting run many times a day. I have searched hidden files and run all programs in safe mode as well. It keeps coming back!

Please help, this is driving me crazy.

They are finding nothing? Have you tried scans from Safe mode woth the AVG and SpyBot? MBAM is stronger in normal mode. Do you have SpyBot's Teatimer function enabled ometimes that will interfere witha scan.

Here's another tool to run...


Please download and scan with 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.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and 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".

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.

No WindowsXP

I have turned on:
- Show hidden files and folders
I have turned off:
- Hide extentions for known file types
- Hide protected operating system files

and am unable to locate any files that look obviously wrong but I do not know what I am looking for.

I probably have some MAC based programs?

Hello again, after some research I find that Threat Expert considers this not a threat.

Across all ThreatExpert reports, the file "mbsmacosxplugin1635.dll" has never been identified as a threat.

http://www.threatexpert.com/files/mbsmacos...in1635.dll.html

I feel the next course of action would be to get another opinion on this file.
Please upload the file to Jotti's malware scan and/or Virustotal . Please post what they send you in your next reply.

Yes, I have read that it is not a big threat. It is driving me nuts not being able to get rid of it. My computer shut itself down unexpectedly yesterday and it completely freaked me out. Why can't I get rid of this thing?

The infected files are now stored in my AVG Virus Vault on my computer. AVG will not let me copy the file from the Virus Vault I can only give the path, does this work?

I appreciate your help very much.

Thanx I will give it a try.

Do you have any clue why I can't get rid of this Trojan? Everyone seems to say that all you should need is AVG 8.0, Spybot Search & Destroy, Malwarebytes Anti-Malware, and SUPERAntivirus free editions. If this is all you need why are we getting these invections we can't seem to cure?

It is possible that this one is being protected by a service running or a driver. We'll see. If we can not get here the HJT Team will..
