ishost and ismon found - please help me remove

By Mystech

  1. Hi guys, well I did something stupid, clicked a random exe file that flooded my system with trojans. My firewall his holding them at bay and AVG managed to get rid of most of them, but I find myself left with these ishost and ismon processes (and files in my windows/system 32 folder) that just won't go away.

    I did a little reading and found that downloading Hijack This and posting a scan log for more knowledgeable users to examine is the thing to do, so here's my long. Please tell me what I've got to do next, or what else you need to know.

    -- Verbose HJT removed --

    Edit: I have now read and understood the rules - relevant files are attached in a post below.

    Please read the instructions at the top of the forum entitled "Read: Follow these instructions BEFORE posting your HJT log." and post a fresh HJT log as a .TXT attachement.

    Let's have another go of it

    Oops, I'm very sorry about that, I didn't mean to break the rules, and should have been more observant. I looked over the thread linked too (and the threads it links to) and run through the steps as they are enumerated therein.

    Enclosed are the logs from my HJT scan and my ewido scan*.

    Note also that since last writing I have identified not only ishost.exe and ismon.exe but also issearch.exe and isnotify.exe running in my processes tab.


    *please note that my ewido scan exceeded 100KB (it came in at about 109.5 KB) and so I was forced to zip it before uploading. If this is not acceptable then I'd be happy to upload it in two separate text files as well.

    Hello and welcome to Techspot.

    Download and run these four tools. Follow the instructions for using each tool.

    Tool1 Tool2 Tool3 Tool4

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

    Regards Howard :wave: :wave:

    Alright, sorry about the delay, I wound up going to bed before this was posted. I want you to know I'm still following the thread, though. I'll preform these steps as you have instructed and get back to you as soon as I have finished.

    Thank You!

    Thanks a ton for your help so far, you're a real life saver. ishost.exe ismon.exe issearch.exe and isnotify.exe all seem to be off of my system now, and I'm no longer getting random advertisement pop-ups at regular intervals.

    I've run all four of those programs, as you instructed, and have attached a fresh HJT log for you to examine.

    Once again, I'm very grateful that you have taken the time to help me with this problem. Your generosity will not be forgotten.

    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.> http://www.bleepingcomputer.com/forums/tutorial61.html

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

    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).

    Fix all 015-trusted zone entries. Never trust anyone.

    O20 - Winlogon Notify: winnbl32 - winnbl32.dll (file missing)

    Click on the fix checked button.

    Close HJT

    Reboot into normal mode and turn system restore back on.

    Post a fresh HJT log.

    I went into safe mode and "Fixed" those entries, as instructed. Here's my new HJT log.

    Just have HJT fix this none required entry in normal mode.

    O4 - HKLM\..\Run: [UserFaultCheck] %systemroot%\system32\dumprep 0 -u

    Other than that, your HJT log is clean.

    If you have any further virus/spyware problems, please post in this thread.
