  1. I followed the entire tutorial to the 'T' http://www.techspot.com/vb/topic50981.html

    I after rebooting in normal mode to do the full virus scan, my AV found about 6 problems. Now when I reboot and scan my AV always comes back with Adware.PurityScan under the entry of C:\Program Files\1~ICROSOFT\lsass.exe

    I also get occasional popups while running Internet Explorer, but so far it has always been a blank popup ad right in the middle of the screen with the address of ad.oinadserver followed by AAAAAAAOOOOOOOOOOOOOOOOOOOOOO or something to that effect. Even though I use firefox, I would prefer not having malware that effects anything on my PC, whether it is a program I use or not. If anyone can help me out i'd appreciate it.

    Posted are my Ewido and HJT log files.

    Hello and welcome to Techspot.

    Download the pocket Killbox programme from HERE. Extract it but don`t run it yet.

    You might want to copy and paste these instructions into a notepad file. Then you can have the file open in safe mode, so you can follow the instructions easier.

    Boot into safe mode, under your normal user name. See how here.> http://www.bleepingcomputer.com/forums/tutorial61.html

    Turn off system restore.(XP/ME only) See how here.> http://www.bleepingcomputer.com/forums/tutorial56.html

    In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how here.> http://www.bleepingcomputer.com/forums/tutorial62.html

    Go to add remove programmes in your control panel and uninstall anything to do with(if there).

    BOONTY

    Click start/run and type services.msc into the run box and press the enter key.

    When the window appears, maximise it. Double click on the following services(if there) and select stop if they are running. Set the startup type to disabled. Click apply/ok for each service you disable.

    BOONTY or Boonty games.

    Close the services window.

    Open your task manager, by holding down the ctrl and alt keys and pressing the delete key.

    Click on the processes tab and end process for(if there).

    Boonty.exe

    Close task manager.

    Run HJT with no other programmes open(except notepad).Click the scan button. Have HJT fix the following, by placing a tick in the little box next to(if there).

    R3 - URLSearchHook: (no name) - _{CFBFAE00-17A6-11D0-99CB-00C04FD64497} - (no file)

    O4 - HKCU\..\Run: [Pydgcdxt] C:\WINDOWS\S?mantec\rundll32.exe

    O20 - AppInit_DLLs: C:\WINDOWS\system32\wuaclt.dll

    O20 - Winlogon Notify: winxtx32 - winxtx32.dll (file missing)

    O23 - Service: Boonty Games - BOONTY - C:\Program Files\Common Files\BOONTY Shared\Service\Boonty.exe

    Click on the fix checked button.

    Close HJT.

    Locate and delete the following bold files and/or directories(if there).

    C:\Program Files\Common Files\BOONTY Shared\Service\Boonty.exe
    C:\WINDOWS\S?mantec\rundll32.exe


    Run the killbox.exe file. When it loads type the full path to the file you would like to delete in the field and check the delete file on reboot button. press the Delete File button (looks like a red circle with a white X). It will prompt you to reboot, select no until you have finished inputting the files you want to delete, only then allow it to reboot and hopefully your files will now be deleted.

    This is the filepath you need to enter into killbox.

    C:\WINDOWS\system32\wuaclt.dll

    Once you system has rebooted, turn system restore back on and post a fresh HJT log.

    Regards Howard :wave: :wave:

    Thanks Howard. I followed your instructions and got rid of the threats you picked from my first log file. My AV still finds the Adware.Purityscan caused by lsass.exe whenever I reboot. Here is my most recent log file.

    It appears that did the trick. Seems like all the problems have been taken care of. If anything else comes up I will just post in this same thread. I appreciate the help, thanks again.

    Howdy, i'm back. My AV still continues to find problems with lsass.exe, and relates it to Adware.Purityscan (more about it in the link)

    http://www.symantec.com/security_response/writeup.jsp?docid=2003-090516-2325-99&tabid=1

    Automatically the file is quarantined (or so it says), and then I attempt to delete it, which always turns out successful (or so it says). Everytime I reboot, my AV notifies me of this problem. I haven't noticed any strange activity going on in the background, popups, slowdowns, or anything abnormal. I'm not sure if the file itself is an infected system file, or if it is an actual duplicate of the original system file (lsass.exe).

    Any experience with this? Suggestions?

    Try the following.

    You might want to copy and paste these instructions into a notepad file. Then you can have the file open in safe mode, so you can follow the instructions easier.

    Boot into safe mode, under your normal user name(NOT THE ADMINISTRATOR ACCOUNT). See how here.> http://www.bleepingcomputer.com/forums/tutorial61.html

    Turn off system restore.(XP/ME only) See how here.> http://www.bleepingcomputer.com/forums/tutorial56.html

    In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how here.> http://www.bleepingcomputer.com/forums/tutorial62.html

    Run a full system scan with your antivirus programme and delete whatever it finds.

    Reboot into normal mode and turn system restore back on.

    Post a fresh HJT log.

    Regards Howard :)
