    Hi olle4k!

    Please cross-check with at least one other scanner, for example
    Trendmicro Housecall:

    http://housecall.trendmicro.com/

    You need Internet Explorer for this one to work..
    It will download engine and pattern file automatically and then
    you can scan your system...

    Another one would be the RAV online scanner:

    http://www.ravantivirus.com/scan/

    Considering the "trojan" classification of AFCore, I found, when browsing the web it also might be a good idea to download a trial version of TDS-3 (an excellent trojan scanner) and the latest radius database and do a memory, process memory and file scan with it

    http://www.diamondcs.com.au/tds

    Good luck!

    I wish you a happy new year!

    Storm

    I recommend that you run Windows in safe mode, then run a full system scan with nod. Oncen nod detect the infected file, you can repair, remove, etc those infected files, but files infected by a trojan in most cases aren't repairable.

    Hi olle4k,

    That´s the one.

    Click "Start" > "Run" > type or copy&paste rundll32 C:\WINDOWS\System32:dpasxib.dll,Uninstall > "OK"

    Then
    Check the following items in HijackThis.
    Close all windows except HijackThis and click Fix checked:
    O4 - HKLM\..\Run: [sys] regedit -s sys.reg

    O4 - HKLM\..\Run: [dpasxib] rundll32 C:\WINDOWS\System32:dpasxib.dll,Init 1

    O4 - HKLM\..\RunOnce: [*dpasxib] rundll32 C:\WINDOWS\System32:dpasxib.dll,Init 1

    Then reboot and delete:
    sys.reg

    Regards,

    Pieter

    Thanks alot Pieter for your time. Before i red your last reply i did fix those two dpasxib.dll and uninstalled them but the system still restarted by it self, can this be becuase of i didnt fix the sys.reg? Anyway, i fixed it now so i hope it will not restart the system for now on, well i hope its gone forever now ;). You said i had to delete sys.reg to, be gentle with me im quite newbie on this :-* but how do i delete what do you mean? I searched for sys.reg but couldnt find nothing.

    Hi olle4k,

    It could already have been removed before. I certainly did not see any indication that it was still present.
    Most likely the startup entry was orphaned, meaning that is was pointing at something that no longer exists.

    Regards,

    Pieter

    I have red other topics about the afcore trojan and people say that their computer reboots by it self becuase of the trojan, and so did mine, and still does? I cant find anything know but it still keep on restarting again and again, maybe this has something to do with some Hardware? But i dont think so becuase it was not like this before

    Here is my new hijack log.
