Hello I have a recurring problem in TROJAN HORSE PSW.AGENT.ABEP. AVG locates and removes it but it keeps recurrring along with a series of other EXE's bacon.exe or bacon(1).exe, 384.exe 949.exe, 764.exe. etc etc It started with the appearance of a hoax (Advanced Virus Remover) infecting my system .
Im running

The advanced virus remover seems to be gone now.

I use AVG which I update daily and adaware anniversary usually. Since the infection Ive run trend Micro, malwarebytes anti malware , superantisypware Ive also scanned with Spyware doctor and prevx. Ive also tried various manual attempts to locate and remove the problem with out sucess .. I get clean scans but it seems to regenerate if I go online. Im not sure what its doing as my system doesnt seem badly affected but Im sure it would be better if I could remove this.

I have Hijackthis installed

Thks for any assistance.

Hello and welcome .. First I have to tell you this may be aserious malware.. Let's get another log please. So we can be certain.

Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

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.

I am also showing this virus. I have run AVG, malwarebytes, hijackthis etc and show multiple instances of run32.dll starting up, causing all manner of processes to randomly die. I acnnot post full logs as I am on a second machine, as this virus has caused all of my intenet browsers to break (even in safe mode).

MalwareBytes picks up the following:
Trojan.Agent - File - C:\Windows\System32\MSIVXcount and the logfile shows it as the only file affected..

Files Infected:
C:\Windows\System32\MSIVXcount (Trojan.Agent) -> Delete on reboot.

However, after several restarts and scans in both normal and safemode this file still pops up.

AVG Antivir shows the result of it's full scan as bacon[1].exe, under detection group TR/PSW/Firefox.EL. Attempts to remove it in safemode etc have been unsuccessful.

As far as I can tell, the HijackThis log doesn't show anything untoward, but again I can't post the log as I'm on a different machine. I've also tried running ComboFix, RootRepeal, CCleaner and Avenger to rid this problem, following the relevant forum instructions. This seems to be a really persistent little blighter, and keeps creating variants of the MSIVXxxxx.xx file in my System32\ folder...

Still, will try other things and report back.

TO RubenRybnik do this but psot it into a new topic..

OK I think we need to run ROOTREPEAL now .. If ypu have log problems i need at least these Stealth Objects
Hidden Services

Next Please install RootRepeal
Note: Vista users ,, right click on desktop icon and select "Run as Administrator."

Go HERE, and download RootRepeal.zip to your Desktop.
Tutorial with images ,if needed >> L@@K.
Unzip that,(7-zip tool if needed) and then click RootRepeal.exe to open the scanner.
Next click on the Report tab, now click on Scan. A Window will open asking what to include in the scan. Check all of the below and then click OK.

Drivers
Files
Processes
SSDT
Stealth Objects
Hidden Services


Now you'll be asked which drive to scan. Check C: and click OK again and the scan will start. Please be patient as the scan runs. When the scan has finished, click on Save Report.
Name the log RootRepeal.txt and save it to your Documents folder (it should automatically save it there).
Please copy and paste that into your next reply.

hello again

here is the scan result requested

SUPERAntiSpyware Scan Log
http://www.superantispyware.com

Generated 07/13/2009 at 06:13 PM

Application Version : 4.26.1006

Core Rules Database Version : 3989
Trace Rules Database Version: 1929

Scan type : Complete Scan
Total Scan Time : 02:19:36

Memory items scanned : 248
Memory threats detected : 0
Registry items scanned : 4569
Registry threats detected : 0
File items scanned : 96360
File threats detected : 0

as you can see it is clean. I have to say that after I did the Anti-Malware scan once Id installed it the way you suggested, I havent had another AVG virus notification since. Ive logged on and off the internet at least 10 times using both using IE and not & whereas before that scan and the removal of the Trojan.DelfInject infection I was getting at least 2 AVG alerts per internet session....

As for my system Im not sure how the infections were affecting it... It didnt seem to be acting up in any particular way. All that was happening after I got rid of the Advance virus remover problems was the constant AVG notifications once Id logged onto the net .

I may be jumping the gun but it seems your advice has done the trick...... Thanks very much.

Hi lenzman,yes I believe we got it. I like to be sure tho there were no others as sometimes these infections bear unwanted gifts.. This looks good so ..
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.
