    I have posted again with HJT as a txt file.

    Hello, I have recently run AVG and come up with a trojan horse in my msconfig file. I let AVG fix/delete the file with system restore turned off. When I reboot it is fine but later that day, it is back.

    Thank you in advance for your help!

    Hello and welcome to Techspot.

    Very Important: Before deciding whether you should clean or reformat your system, go and read this thread HERE and decide what it is you want to do.

    If after reading the above, you wish to clean your system, do the following.

    Go and read the Viruses/Spyware/Malware, preliminary removal instructions. Follow all the instructions exactly.

    Post fresh HJT, AVG Antispyware and Combofix logs as attachments into this thread, only after doing the above.

    Also, let me know the results of the AVG Antirootkit scan.

    Regards Howard :wave: :wave:

    H_H, Thanks for the reply.

    I have run through the list of items to complete and I have attached the log files here.

    One thing that I am starting to get now is "UsrRsltMd5AddApp: you have too many application already registered!" from the program files\kerio\personal firewall\persfw.exe and when I close the window, it comes up over and over on the screen.

    Thanks again for the help!

    You`re running an outdated version of HijackThis. Uninstall your current version and install the new version as per the instructions in this thread HERE.

    You`re also running a completely unpatched version of Windows. This is a huge security risk. Go HERE and download and install Windows sp1a.

    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(NOT THE ADMINISTRATOR ACCOUNT). See how HERE.

    In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how HERE.

    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).

    Click on the fix checked button.

    Close HJT.

    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. If your computer doesn`t automatically restart, restart it manually.

    This is the filepath you need to enter into killbox.

    C:\windows\system32\msvcrt62.dll

    Once your system has rebooted, rehide your protected OS files.

    Post a fresh HJT log and let me know the results of the AVG Antirootkit scan.

    Regards Howard :)

    Howard, thanks for all the help here. Attached is my HJT log. I ran the antirootkit and it didnt find anything.

    I am still getting the error "UsrRsltMd5AddApp: you have too many application already registered!" from the program files\kerio\personal firewall\persfw.exe and when I went to delete the program to reinstall it, I get a rundll error loading it in the remove programs screen saying the specific module cannot be found. Any thoughts?

    Also, I was not able to run the sp1a with the copy of windows that I have. Seems that it wasnt a full true copy that I was given... the copywright error came up.

    Your HJT log is clean.

    I suggest you redownload and install Kerio. See if that helps.

    Regards Howard :)
