HI

AVG 8.5 has informed me of trojan infection 'trojan horse agent.4.ak' on my PC. AVG says that it has been successfully remove but the trojan reappears after a restart and rescan.

Kaspersky online scan informs me of trojan infection 'trojan.win32.small.aarn'

Both Trojans are located in the same Folder/File C:\windows\slci.arm.

I'm also running PC Tools Spyware Doctor which when scanned does not find these 2 infections.

Symptoms of infections: AVG won't auto update (updated manually ok), web sites I've not requested, Internet connection interference, & occasional very slow performance.

I've not attached a DSS report as although downloaded to my desktop, when run the DSS information screen pops up blank and then immediately disappears.

Thanks in advance for any help and advice.

Some types of malware will disable MBAM 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..
  • Another work around is by not using the mouse to install it, Just use the arrow keys, tab, and enter keys.

Please download Malwarebytes Anti-Malware and save it to your desktop.
  • 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 updates, manually download them from here or 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 and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

Please include the following in your reply:

I've just noticed that on the MBAM log I previously posted the database version was 1945 even thought I updated it to version 2060.

So I did a reboot and here's the new MBAM log with correct database version.

Please download DrWeb-CureIt and save it to your desktop. DO NOT perform a scan 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 Dr.Web CureIt as follows:
  • Double-click on drweb-cureit.exe to start the program.
  • Cancel any prompts to download the latest CureIt version and click Start.
  • At the prompt to "Start scan now", click Ok. Allow the setup.exe/driver to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
  • When complete, click Select All, then choose Cure > Move incurable.
    (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • Now put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
  • Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)
