    [​IMG] Download HijackThis 1.99.1

    [​IMG] Unzip the hijackthis.exe file to a folder you create named C:\Program Files\HJT

    [​IMG] 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 ZIP file as your backups will not be safely stored.

    [​IMG]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.

    First, temporarily disable Spybot S&D TeaTimer as this will cause problems with this fix.


    Please print out these instructions so that you can operate with All Browser Windows CLOSED.

    Please make sure System Restore is OFF and the Viewing of Hidden Files & Folders is Enabled as per the tutorial.


    Now, look in Task Manager (Ctrl-Alt-Del) for the following running process and, if you see it, try to END it:

    epbwosp.exe

    Now scan with HijackThis and Check the Boxes for the following:

    Make sure All Browser Windows are Closed when you Click FIX.

    R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = http://bestfind4u.com/sp.htm
    R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Page = http://bestfind4u.com/index.htm
    R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = http://bestfind4u.com/index.htm
    R0 - HKLM\Software\Microsoft\Internet Explorer\Search,SearchAssistant = http://bestfind4u.com/sp.htm
    R1 - HKCU\Software\Microsoft\Internet Explorer\SearchURL,(Default) = http://bestfind4u.com/index.htm

    O2 - BHO: (no name) - {AC1D8017-4FED-468E-B7F5-66F8C81A5923} - C:\WINNT\system32\hclm.dll (file missing)

    O4 - HKLM\..\Run: [NTSF MICROSOFT SYSTEM] rtnfs.exe
    O4 - HKLM\..\RunServices: [NTSF MICROSOFT SYSTEM] rtnfs.exe
    O4 - HKCU\..\Run: [internat.exe] internat.exe
    O4 - HKCU\..\Run: [bjbadha] c:\winnt\wcoeovj.exe
    O4 - Global Startup: 902465.exe

    O9 - Extra button: Related - {c95fe080-8f5d-11d2-a20b-00aa003c157a} - C:\WINNT\web\related.htm
    O9 - Extra 'Tools' menuitem: Show &Related Links - {c95fe080-8f5d-11d2-a20b-00aa003c157a} - C:\WINNT\web\related.htm

    Again, make sure All Browser Windows are Closed when you Click FIX.

    NOW:
    Please boot into Safe Mode with the Viewing of Hidden Files & Folders Enabled and navigate to and DELETE the following if they should remain:

    C:\WINNT\epbwosp.exe

    C:\WINNT\wcoeovj.exe

    C:\WINNT\web\related.htm

    902465.exe ←–– Search for this file and delete if found!

    rtnfs.exe ←–– Search for this file and delete if found!

    NEXT:
    Run CCleaner and Spybot S&D and have Spybot fix what it finds.
    Note: Dont forget to update Spybot S&D by selecting "Search For Updates"

    Then, as an added precaution, Go to Start > Run and type: cleanmgr and then click OK. Make sure the boxes for these are checked:
    Temporary Files
    Temporary Internet Files
    Recycle Bin


    And Click OK.


    Reboot to Normal Windows

    FINAL STEP

    Reset Web Settings & Default Security Settings:


    To Reset Web Settings:
    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.

    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


    To Default Security Settings:
    Right click on your desktop Internet Explorer icon and select Properties. Then click the Security Tab and click Default Level for Internet, Local Intranet, Trusted Sites, and Restricted Sites.


    After doing ALL of the above,
    Scan with HijackThis and attach the new log.
    Let me know of any problems you may have encountered with the above instructions and also let me know how things are running now.

    Good Luck!:)

    I followed your instructions. Thankyou bjgarrick, it was a complete success.

    One question: the malicious .exe file 'wcoeovj.exe' seems to generate a different name on every reboot, to another 7-letter name. Perhaps this is where the file epbwosp.exe originated from? When I rebooted to normal mode, another 7-letter .exe file tried to take the place of wcoeovj.exe (according to the hijackthis! log).
    My question is, the WINNT directory currently holds about 50 of the 7-letter .exe files, could any of these files be system files or would they all be differently named versions of the malicious .exe file? Basically, I am unsure whether I should delete all of these files.

    Thankyou very much for your help bjgarrick and majorgeeks!
