Ishost.exe Problems

[umne]

Hello, i have come here in search of aid. I am not very skilled on the computer, and i was trying to download a file when i came across Ishost.exe and a Ismini.exe. Is there any way to solve this problem and get rid of them, if so where should I begin to get a proper help page set up for it.

Hello and welcome to Techspot.

Go HERE and follow the instructions exactly. There are tools within the instructions, that will get rid of Ishost.exe/ismini.exe.

Post a fresh HJT log as an attachment, only after doing the above.

I Managed to Remove those two, but i am still experiencing some problems since then. When the two were in my task manager, my firewall went down and now they are not here my firewall is still down. but here is my HJT log.

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.

Turn off system restore.(XP/ME only) See how here.> http://www.bleepingcomputer.com/forums/tutorial56.html

Boot into safe mode, under your normal user name(NOT THE ADMINISTRATOR ACCOUNT). See how here.> http://www.bleepingcomputer.com/forums/tutorial61.html

In Windows Explorer, turn on "Show all files and folders, including hidden and system". See how here.> http://www.bleepingcomputer.com/forums/tutorial62.html

Click start/run and type services.msc into the run box and press the enter key.

When the window appears, maximise it. Double click on the following services(if there) and select stop if they are running. Set the startup type to disabled. Click apply/ok for each service you disable.

Close the services window.

Open your task manager, by holding down the ctrl and alt keys and pressing the delete key.

Click on the processes tab and end process for(if there).

Click on the fix checked button.

Close HJT.

Locate and delete the following bold files and/or directories(if there).

C:\WINDOWS\system32\NvVid.exe

lockx.exe Search your system for this file and delete all instances of it.

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.

This is the filepath you need to enter into killbox.

C:\WINDOWS\SYSTEM32\winwim32.dll

Once your system has rebooted, turn system restore back on and rehide your protected OS files.

Reinstall your firewall software.

Post a fresh HJT log and let me know how your system is running.

something happened during this process, i am currently on another computer. AS i followed those instructions to the best i could have, to the end i lunch killbox and rebooted. Now as i try to go back onto windows i keep getting a bloow screen quickly flash with some text, then the compter reboots again, and the cycle continues. I had to enter again into Safe mode, any idea on what could have gone wrong and the solution.

 

[howard_hopkinso]

Have you tried last known good config?

If that doesn`t work, boot into safe mode and go to c:\windows\minidumps attach the latest 5 or 6(if you have that many) minidumps into this thread and I`ll take a look at them.

Regards Howard

 

[umne]

How can i tell which are the 5 or 6?

 

[howard_hopkinso]

If you hovver you mouse pointer over the files, it will give you date and time info.

I take it you`ve got lots of them?

Regards Howard

 

[umne]

yes i have many, but i will get the most recent ones for you

 

[umne]

here are my most recent ones, i hope they help

 

[howard_hopkinso]

4 of your minidumps crash at your video card drivers. They have bugchecks of 50 and 8E.

1 minidump crashes at ntoskrnl.exe. This is the Windows bootup kernel file. It has a bugcheck of DI

Boot into safe mode and uninstall your videocard drivers. See if that allows you to boot normally.

Please let me know.

Regards Howard

Unfortunately it still was not able to work, i am quite concerned, and am wondering if reformatting the computer using the recovery disks would solve it.

 

[howard_hopkinso]

Oh dear.

I take it you don`t have a Windows XP disk?

First thing to try is a recovery. Sounds like the ntoskrnl.exe file has become corrupt for some reason.

On the other hand, it could be caused by a hardware problem, but let`s hope not.

Regards Howard

 

[umne]

Not that i can recall, i am using a sony vaio, and i don't think it came with a windos XP disk, just a system and application recovery set of disks is all.

how would i try a recovery?

 

[howard_hopkinso]

Try the recovery and see if that helps. If not, a reformat is probably the way to go.

I`m sorry you`re having so many problems.

I doub`t very much, whether your problems are caused by the Viruses/spyware you were trying to get rid of, unless you`ve accidently deleted something critical by mistake.

Regards Howard

 

[umne]

yes thank you for all your help though, i just want to know how i would go about doing a recovery.

 

[howard_hopkinso]

The instructions should be on the recovery disks themselves. I can`t give you exact instructions as I`ve always had a proper Windows XP disk.

Your Laptop manual may also have instructions.
