Hi, I've had this problem for about a week now. Something seems to have gotten onto my computer. The main thing I notice is there is a program called brastk.exe that gets autorun on startup. There are also a number of startup entries in msconfig that reactivate even if I disable them. They are:
"rundll32" which runs a dll called drkly16j.dll
"dumprep 0 -u"
"brastk.exe"

If I delete brastk.exe or drkly16j.dll they just get recreated on the next boot. It appears that something besides a program is running at startup, possibly a service or a program running on shutdown. There is also something redirecting my google searches, and when I plug in my flash drive an autorun file gets created along with a file called system.exe.

EDIT: uh-oh, I just tried to run HJT and Spybot and neither will start! No error messages, just double clicking on the program and nothing happens.

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 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.

I did the scan while running my computer with all non-microsoft services and all startup programs disabled. Should I re-enable them and rescan?

Here's the log:

Thanks for the quick replies, but I think I have gotten rid of it. I used MBAM in safe mode to delete the files and disabled the startup entries. Everything including the google redirection seems to be working fine.

Uh oh, having problems again. After running MBAM and removing brastk.exe and all other infected files, some of the files needed a rebot to be deleted. So I did just that, and everything was going fine. I ran MBAM and it found two files it was detecting as rootkits. After multiple attempts to remove then with MBAM I gave up and let it be for a while. My computer then rebooted abruptly, and the brastk.exe and all the other files were there again. What should I do?
(I am sorry if this topic is dead, if required I will make another)

Here is a log from when the startup items are not disabled.
