    In the future please do not post HJT logs unless they are requested. You have multiple problems that need to be fixed. This will take a few iterations.

    First you must disable Spybot's Teatimer because it can get in the way of our cleanup process.

    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!

    Please download: HSFix.zip
    Extract the files from the ZIP File to a folder that you can find (preferably in its own folder - like c:\HSFix). Now boot to Safe Mode open the HSFix Tool folder and doubleClick hsfix.bat and let it run. It will produce a log here - C:\hslog.txt

    Now reboot in normal mode and post that hslog.txt file here as an attachment.
    After doing the above move on to the next message.

    Do you know what this next line is?
    O21 - SSODL: Audio Conversion Wizard_is1 - {DF793238-1D40-716D-346A-485428B1C2E2} - c:\program files\covert to mp3 towav\audio conversion wizard\wxrlonk9.dll

    Continue with the cleanup below!

    Click on Start, then Run ... type services.msc into the box that opens up, and press 'OK'.
    On the page that opens, scroll down to svchost.exe (or if not found, look for moto) ... right click the entry, select 'Properties' and press 'Stop Service'. When it shows that it is stopped, next please set the 'Start-up Type' to 'Disabled'. Press 'OK' until you get back to Windows.

    Next, open up HJT, but instead of scanning, click on the "None of the above, just start the program" button at the bottom of the choices. At the lower right, click on the 'Config" button, and then the Misc tools' button ... select 'Delete an NT Service" ... copy/paste the following into the box that opens, and press "OK":

    svchost.exe

    If that does not work, try using: moto

    Now exit HJT. You may be told you have to reboot to complete the process. Do not reboot yet. We will be restarting HJT in a few lines to fix some other items first.

    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).

    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:

    O23 - Service: svchost.exe (moto) - Unknown owner - C:\WINDOWS\svchost.exe (file missing)

    After clicking Fix, exit HJT.
    Boot into safe mode and use Windows Explorer to delete:
    C:\WINDOWS\System32\symcsvc.exe
    C:\WINDOWS\SYSTEM32\drct16.dll

    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 we need 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.

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

    Hi Chaslang,

    as requested attached is the HSlog file.

    while completing suggestions in the second post i found that

    "After clicking Fix, exit HJT.
    Boot into safe mode and use Windows Explorer to delete:
    C:\WINDOWS\System32\symcsvc.exe
    C:\WINDOWS\SYSTEM32\drct16.dll"

    C:\WINDOWS\System32\symcsvc.exe
    did not exist, this is a good thing right?

    Then while I was reseting web settings, as soon as i clicked control panel the comp froze. SO I rebooted again and carried out the instructions again.

    also attached is the HJT log.
    I think everything is working fine now. How does my logs look?

    and I had to uninstall Norton AV and internet security do you think I should reinstall them or go with some other programs?

    Kind regards

    SN :confused:

    That's because you now have some new problems. This is probably happening because you OS and IE versions are way out of date and need to be updated. But let's wait until we fix your current problems first.

    You did not answer my question about what the below is:

    O21 - SSODL: Audio Conversion Wizard_is1 - {DF793238-1D40-716D-346A-485428B1C2E2} - c:\program files\covert to mp3 towav\audio conversion wizard\wxrlonk9.dll

    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).

    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:
    O3 - Toolbar: (no name) - {42CDD1BF-3FFB-4238-8AD1-7859DF00B1D6} - (no file)
    O4 - HKLM\..\Run: [SysMemory manager] c:\windows\system32\mdms.exe
    O4 - HKLM\..\Run: [hclean32.exe] C:\WINDOWS\System32\hclean32.exe
    O4 - HKLM\..\Run: [dmzun.exe] C:\WINDOWS\System32\dmzun.exe
    O16 - DPF: {33564D57-0000-0010-8000-00AA00389B71} -

    After clicking Fix, exit HJT.
    Boot into safe mode and use Windows Explorer to delete:
    c:\windows\system32\mdms.exe
    C:\WINDOWS\System32\hclean32.exe
    C:\WINDOWS\System32\dmzun.exe

    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.

    Hello again,

    First before I forget

    O21 - SSODL: Audio Conversion Wizard_is1 - {DF793238-1D40-716D-346A-485428B1C2E2} - c:\program files\covert to mp3 towav\audio conversion wizard\wxrlonk9.dll

    refers to Audio conversion wizard, a freeware program which helps to convert files to mp3 format, if you think that this program is/will cause problems I can uninstall (please advise)

    Second I double checked and System Restore is off and viewing of all hidden types is enabled

    Next:
    I couldnt find

    C:\WINDOWS\System32\dmzun.exe

    to delete it. I did a search and the file actually existed 5 times in

    C:\Recycler\S-1-5-21-1409082233-764733703-854245398-1003
    C:\Recycler\S-1-5-21-1409082233-764733703-854245398-1004
    C:\Recycler\S-1-5-21-1409082233-764733703-854245398-1005
    C:\Recycler\S-1-5-21-1409082233-764733703-854245398-1006
    C:\Recycler\S-1-5-21-1409082233-764733703-854245398-1007

    After running ccleaner the file was no longer found.

    Attached is my new HJT log.

    While in safe mode my comp was reponding painfully slowly, until the following message showed

    WINDOWS - VIRTUAL MEMORY MINIMUM TOO LOW

    Your system is low on virtual memory. Windows is increasing the size of your virtual memory paging file. During this process, memory requests for some applications may be denied.

    Now that i am in normal mode, it doesnt seem to be too slow.

    any suggestions?

    Regards

    SN

    PS. thank you for your help so far!

    Do not worry about the O21 line. I just wanted to make sure that it was something you knew about.

    The reason you could not find the C:\WINDOWS\System32\dmzun.exe file is because this nasty piece of malware is renaming itself each time you power down your PC. Now the problem line is:

    O4 - HKLM\..\Run: [dmrdh.exe] C:\WINDOWS\System32\dmrdh.exe

    You need to fix that line and delete the file in safe mode. But if you rebooted since posting your log, it may already have renamed itself. Take a look now and verify for yourself what the file name is and fix the O4 line and delete the file. You should be able to tell which line does not belong there.

    If you still have a problem after trying to fix this again, post a new HJT log and do not reboot or power down afterwards.

    hi

    i have managed to delete the file and line concerned.

    but (there is always a but!)

    I have noticed that mdms.exe keeps coming back.

    At first i cant delete it and it wont show up on task manager either (and its not protected)

    so i tried renaming and then deleting. I get the same error, but this time mdms.exe shows up in task manager and i am able to kill it. and deletion is sucessful. however as soon as i get out of the folder C:\windows\systems32 the file comes back and i have to do the whole thing again. it shows up even if i just navigate to c:\windows

    why is this happening! and more importantly how can i fix it?
    I have attached my latest hjt log and havent rebooted ( i am using my laptop to post this message)

    Also I keep getting the Virtual memory error message and then cant do anything. The comp isnt froxen it just wont open any applications including windows explorer ( i can even click on the start menu, but nothing else happens) Hmmmm... have to reboot!

    ok... so attached is the new log, after I have done all of the above again also please note that HJT found mdsm.exe as well, i was able fix it and then delete it using windows explorer and it hasnt come back as yet.

    Cheers

    Safe mode HJT logs are of know use to us in 99.9% of all cases. Your safe mode log shows nothing. I would need a log from normal boot mode that shows the problems being present (i.e., do not fix anything or I will not see it).

    I think that you will need to goto the below thread and complete the step number 3 and 7 for now (do not run other steps yet). Without a firewall, your problems will just keep coming back.

    How to Protect yourself from malware!

    You will have to ask about your Virtual Memory Problem in the Sotware Forum. I do not thing it is a malware problem.

    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).

    Please run HijackThis and click on the "Open the Misc Tools Section" button on the open page. Then select "Open process manager" on the left-hand side. Look for the following process (or processes) and one at a time kill them by selecting it and then click "Kill process". Then click yes.
    C:\windows\system32\mdms.exe

    After killing all the above processes, click "Back".
    Then please click "Scan" 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:

    O4 - HKLM\..\Run: [SysMemory manager] c:\windows\system32\mdms.exe


    After clicking Fix, exit HJT.

    Boot into safe mode and use Windows Explorer to delete:
    C:\windows\system32\mdms.exe


    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.

    If you get a message from your firewall about mdms.exe trying to access your network or the internet, deny it access and tell it to always do that.

    If the above works correctly and removes the final problem, you would then need to go to bacto the How to Protect yourself from malware! thread and complete all the other steps. Especially step 1.

    If you still need help, leave a message here indicating your problems. I will not be around for about 10 days but one of the other helpers here will assist you.
