Hijacked by Hotoffers

    My Win98 first edition machine has been hijacked by hotoffers. After reading the thread from marciow I'm now not surprised that 5 different Spyware programs (Yahoo toolbar, Spy Sweeper, Spybot 1.3, Ad-Aware, and Spyware Doctor) could not get rid of this thing.

    It appears the final fix by marciow was to download an uninstaller from hotoffers itself (http://www.hotoffers.info/uninstall/uninstall.exe) - should that be tried first or as a last resort? It seems a little risky.

    Your help is very much appreciated. This is a real pain in the backside.

    Thanks chaslang. I went thru the list of things major attitude suggested trying. I did everything up to before doing Hijack this. I would like to try to hotoffers uninstaller - the other alternate scans have little chance of success. I could not find the uninstaller at hotoffers - the link in your message could not be displayed Can you help locate this file?

    I have saved all key data and program files to CD in case this machine turns into a pumpkin.

    Thanks,

    Jim

    We have found that the people responsible for this junk have now removed the uninstaller. Probably because they found out that everyone in the world was using it.

    If you have completed all the steps in the READ ME, follow the steps below and lets see what we can do with this thing manually.

    - Download HijackThis 1.99.1

    - Unzip the hijackthis.exe file to a folder you create named C:\Program Files\HJT

    - Do NOT run Hijack This from the Desktop, a temp folder, or a sub-folder of C:\Documents and Settings, or choose to run it directly from the downloaded ZIP file.

    - Before running HijackThis: You must close each of the following:your web browser, e-mail client, instant messenger, and programs like notepad, wordpad, MS Word etc. And any other unnecessary running programs.

    - Run HijackThis and save your log file.

    - Post your log as an ATTACHMENT to your next message. (Do NOT copy/paste the log into your post).

    After we get your current problems fixed, you must go to Windows Update and get your updates. You are seriously out of date.

    I assume all the below Proxy settings are required by your ISP (is that AT&T):
    R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyServer = ftp=12.242.19.9:8000;gopher=12.242.19.9:8000;http=12.242.19.9:8000;https=12.242.19.9:8000
    R1 - HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings,ProxyOverride = 12.242.19.9


    I'm not sure what this msvcrtd.exe file is for. Can you get Properties info on the file?
    O4 - HKCU\..\Run: [MSVCRTD] C:\WINDOWS\SYSTEM\MSVCRTD.EXE

    If you are using WinXP or WinMe, make sure you have system restore disabled (per the tutorial).
    For all OS types, make sure viewing of hidden files is enabled (per the tutorial).


    Download Pocket Killbox from here: http://www.downloads.subratam.org/KillBox.zip
    Unzip the files to its own folder (like C:\killbox).

    Double-click on "Killbox.exe" to run it.
    Put a checkmark in "Replace on Reboot" and the "Use Dummy" box.
    Copy/Paste the below two files (one at a time) into the top "Full Path of File to Delete" box.

    Click the "Delete File" button which looks like a stop sign.
    Also checkmark the "Replace on Reboot".
    Click "NO" at the Pending Operations prompt to restart your computer.

    C:\WINDOWS\System32\systr.dll
    C:\WINDOWS\System32\param32.dll

    After pasting in both of the files named above, look on the killbox top bar and press "Tools" > "Delete Temp Files"

    Now exit Killbox!

    Run HijackThis and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:
    R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://www.hotoffers.info/ad0058/
    R3 - URLSearchHook: (no name) - {C7EDAB2E-D7F9-11D8-BA48-C79B0C409D70} - (no file)
    O2 - BHO: SideStep Browser Helper - {08351226-6472-43BD-8A40-D9221FF1C4CE} - C:\WINDOWS\DOWNLOADED PROGRAM FILES\SBCIE026.DLL
    O2 - BHO: (no name) - {5C8B2A36-3DB1-42A4-A3CB-D426709BBFEB} - (no file)
    O9 - Extra button: SideStep - {3E230861-5C87-11D3-A1C6-00105A1B41B8} - C:\WINDOWS\DOWNLOADED PROGRAM FILES\SBCIE026.DLL
    O16 - DPF: {0837121A-6472-43BD-8A40-D9221FF1C4CE} (SideStep IE Inst) - http://download.sidestep.com/get/k00719/sb01f.cab
    O16 - DPF: {1D0D9077-3798-49BB-9058-393499174D5D} - file://c:\counter.cab

    After clicking Fix, exit HJT.

    Boot into safe mode and use Windows Explorer to delete:
    c:\counter.cab

    double check for these too and delete if found:
    C:\WINDOWS\System32\systr.dll
    C:\WINDOWS\System32\param32.dll

    Additional step to delete SBCIE026.DLL:
    - Click Start, Run, and enter command in the box and click OK. This opens a command prompt window.
    - Enter the following command lines each followed by the enter key
    cd "C:\WINDOWS\Downloaded Program Files"
    attrib -r -h -s SBCIE026.DLL
    del SBCIE026.DLL
    exit


    If you get an error when deleting a file. Right click on the file and check to see if the read only attribute is checked. If it is, uncheck it and try again. Other wise open Task Manager and kill the process if running then delete the file.

    Now run Ccleaner (installed while running the READ ME FIRST). Now if running Win XP goto c:\windows\Prefetch and delete all files in this folder.

    Now reboot in normal mode and post a new HJT log. And tell us how things are working.

    Thanks for all the things to try but still have the hijacker.

    I've just learned about Windows Update so updated my new desktop to XP Home SP2. What can be updated for a first generation WIN98 machine?

    The R1 proxy settings - I don't have AT&T anymore - I now have Comcast cable internet. Should these be deleted as well?

    File C:\windows\system\msvcrtd.exe is no longer on my C drive. The Norton internet security program deleted it last week since it thought it contained a trojan. There is still a msvcrtd.dll file on my machine - should it be deleted as well?

    I ran pocket killbox on systr.dll and param32.dll. Systr went away and param32 did not.

    When I went to run HJT the hijacker opened dozens of IE sessions and I had to reboot the machine.

    Ran HJT and deleted these item. Restarted in safe mode. Did not find any file C:\counter.cab. There is a file c:\counter.zip which contains counter.exe and counter.inf. Should these be deleted?

    Systr.dll and SBCIE026.dll were deleted and not found by explorer. Param32.dll was still there and I could not delete from explorer since "windows was using that file". I tried to delete from the dos prompt and was told "access denied". That file was dated 4/18/05 - around the time this hijacker showed up and also I installed Norton Internet security around that time (that directory also has a popup blocker dll with the same date/time so I'm suspecting Norton here). Ran Ccleaner and rebooted in normal mode. Hijacker is still here. Attached is the latest HJT log file.

    Thanks,

    Jim

    Windows update works for Win98 too! Perhaps you should do that right now because your really need the security fixes and updates to IE. Click the below link and do step # 1.

    How to Protect yourself from malware!

    Yes!

    No!

    We must get rid of param32.dll. We will use a boot to DOS mode later.

    Yes!

    Please disable C:\PROGRAM FILES\SPYBOT - SEARCH & DESTROY\TEATIMER.EXE
    To disable TeaTimer, run Spybot and click Mode and select Advanced Mode. Then click Tools and select Resident. Now in the right window pane, uncheck TeaTimer.
    Also while this is open, in the left column now select IE Tweaks and then in the right pane make sure all the Miscellaneous locks are unchecked.
    Now quit Spybot!

    I'm not sure where the param32.dll files was on your PC. So if I have the wrong folder info below substitute the correct info.

    Now we are going to reboot your PC to an MSDOS prompt.
    Click Start and select Shutdown and in the Window that comes up choose the one that says Restart the computer in MD-DOS mode.

    When it boots you will be at the command prompt (full screen) enter the below commands each followed by the enter key. Let me know if you have any problems or get any error messages during these steps (tell me the exact error message).

    Now in command prompt window do the following:

    cd c:\windows\system32
    attrib -s -h -r param32.dll
    del param32.dll
    win

    Now your PC will boot normal Windows

    Come back and tell me the results. Fix the hotoffers line in your HJT log now if possible.

    I deleted the R1 proxy settings and counter.cab. TeaTimer in Spybot is disabled. I did manage to delete param32.dll using DOS mode - it turns out it was part of Norton Internet security since it said it was disable in the system tray on normal reboot. No big deal - it was a trial subscription anyway.

    I tried to delele the RO line with hotoffers in it with HJT but it would not go away. Hotoffers is still here. Attached is my latest HJT logfile.

    Boot into safe mode (or to the command prompt) and see if you can locate and delete any of the below files:
    systr.dll <-- I know we deleted it earlier. I'm double checking
    popup_bl.dll
    INTLMAIN.DLL
     
  12. jimmtman

    jimmtman Private E-2

    The only file that was there was popup_bl.dll (which is a Norton Internet Security file) and it has been deleted.

    Jim
     
  13. chaslang

    chaslang MajorGeeks Admin - Master Malware Expert Staff Member

    Hmmm! So you are saying that both param32.dll and popup_bl.dll belong to Norton?
     
  14. jimmtman

    jimmtman Private E-2

    I believe so -the reason I say that is both these files had the same creation time and when I deleted param32.dll Norton Internet Security said it was disabled.

    Hotoffers is still there but not as aggressive as before. It comes up less frequently - looks like we are making progress.

    A friend of mine suggested looking at the registry and deleting things that look out of place. What do you think of that? Does HJT do this already?

    HijackThis is showing you some registry entries that are frequently used by malware.

    Looking at the registry for things that are "out of place" will take you a couple of months. The registry is huge and there are thousands of places to look and you need to know what you are looking for too.

    We need to find a file that is actually the cause of this problem. That's the difficult part.

    I don't think either of those files had anything to do with Norton. Please search your PC for the below files and let me know if you find them anywhere. You have to configure search to look for hidden files first (see further down on how to do that):

    param32.dll
    guninst.exe
    popup_bl.dll

    How to use windows XP search mechanism to look for hidden files:

    Click Search and the Select "All files and folders"
    Enter the filename in the "All or part of the file name:" box
    Now select "More advanced options"
    Make sure the following check boxes are checked:
    - Search system folders
    - Search hidden files and folders
    - Search subfolders
    Then click the Search button.

    I found guninst.exe and deleted it. Param32.dll and popup_bl.dll were not there.

    The computer is running much better. Once inside EI the hijacker does not change locations. It used to change sites every 5-15 minutes - nothing has happened in 40 minutes. Also there used to be a Windows system message that would pop up saying your computer was infected with spyware and to click a button to fix it (I suspect this was part of the spyware). That window doesn't come up anymore either. Given that the improvement happened yesterday I'm suspecting it was most likely due to deleting Paras32.dll or popup_bl.dll. Both of these files (and guninst.exe) were in C:\windows\system32.

    The first time IE opens it still goes to hotoffers - so it appears to have been set as my default website. What is the best way to change to another website on startup?

    Thanks,

    Jim

    How to Reset Web Settings:
    1) If you have an Internet Explorer icon on your Desktop, goto step 2. If not, skip to step 3.
    2) Now right click on your desktop Internet Explorer icon and select Properties. Then click the Programs tab and then click "Reset Web Settings". Now go back to the General tab and set your home page address to something useful like www.majorgeeks.com. Click Apply. Click Delete Cookies, Click Delete Files and select Delete all Offline content too, Click OK. When it finishes Click OK. Then skip step 3.
    3) If you do not have an Internet Explorer icon on your Desktop, click Start, Control Panel (for some systems it may be Start, Settings, Control Panel), Internet Options, Programs tab and then click "Reset Web Settings". Now go back to the General tab and set your home page address to something useful like www.majorgeeks.com. Click Apply. Click Delete Cookies, Click Delete Files and select Delete all Offline content too, Click OK. When it finishes Click OK.

    After doing the above reboot and make sure that hotoffers no longer comes back.

    Hotoffers is gone!!

    Thanks very much for all your help. Hotoffers is gone entirely. I need to do a bunch of updating/protecting for my system. I've made a list of a few things - your advice on what else to do is much appreciated.

    Windows Update
    Change to Sun Java
    IE Update?

    Anti-Virus software - I've heard free ones like AVG work well or it is worth the money to get Norton or McAfee?

    Firewall - I've heard that Zone Alarm is free and works well. Is it worth it to pay for one from Norton or McAfee? They are often bundled in something called Internet Security.

    Do I need to reset any anything for the spyware tools I've downloaded (Spybot TeaTimer for instance) now that the system is clean?

    Thanks again,

    Jim

    Personally I consider McAfee and Norton to be too much of a resource hog. The free programs work very well.

    I use Spybot but do not enable the Teatimer function. I have other active blocking from MS Antispyware (on some PCs) and SpySweeper on other PCs.
