hi, it has been some time since anythng got me foxed but i could really use some assistance with this one please.

basically i have a persistent problem. i use windows onecare and each time i start the PC it picks up several attempts to drop trojans. one care can clean them but does not seem to locate the sorce file which is instructing the drop. i havetaken several steps to fix the problem none of which have suceeded.
my steps were.

inspection if hijack this logs - couldnt see anything obviously wrong
cleaning registry and start up entries, i was uncertain about a couple of them but nothing stood out.
checking running processes - again i can't see anything obvious.
manual search of win32 fils for anomalies, - this yielded several rogue .exe files and a couple of bitmaps, but i have to assume these were droped and not the source file.
running onecare virus scan - finds nothing
running malwarebytes scan - initially found a raft of infections and removed them but further scans yield nothing and the problem persists.

clearly it seems i have a hidden file somewhere which is causing this to happen, i really do think there must be something in the start up .exe's as the problem always occurs on restart.

help please, i am somewhat reluctant to simply wipe and start again from scratch as i have a whole heap of music editing software which will take several days to reinstall

here is my hijack this log, all halep and assistance gratefully received, many thnks in advance. now that i look at it again i can se a couple of suspicious looking things but i will wait for help before doing anything further. thanks.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on Download_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 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 and you may be prompted to restart your computer. (see Note below)
  • 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 will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.
