  1. I've just followed all the steps on 8-step Viruses/Spyware/Malware. Internet Explorer is initially starting up on startup and then closes itself. But according to comodo it runs in the background. I think it may be trying to contact an address and dl and install some malware. Any help is appreciated. Thanks

    These entries in the hijackthis log look suspicious:
    "6 - DPF: {6414512B-B978-451D-A0D8-FCFDF33E833C} (WUWebControl Class) -"...
    "O16 - DPF: {6E32070A-766D-4EE6-879C-DC1FA91D2FC3} (MUWebControl Class) -"...
    "O4 - HKUS\S-1-5-18\..\Run: [DWQueuedReporting] "C:\PROGRA~1\COMMON~1\MICROS~1\DW\dwtrig20.exe" -t (User 'SYSTEM')"...
    "O4 - HKUS\.DEFAULT\..\Run: [DWQueuedReporting] "C:\PROGRA~1\COMMON~1\MICROS~1\DW\dwtrig20.exe" -t (User 'Default user')"...

    Delete these entries

    O4 - HKLM\..\Run: [NetSoft] iexplore.exe

    I've removed the iexplore entry. But every time i use internet explorer, it starts up the way it did on startup. It comes on closes the window and runs in the background seemingly trying to contact an address without my knowledge. then when i try to startup iexplorer I've noticed 2 instances of it running: the one hiding in the background and the active window I've opened. The original entry that i deleted has also reappeared. i've decided to just block the active process using comodo in the meanwhile. Any other ideas?

    Ronalan, Welcome to TechSpot. I'll be glad to help you get rid fof the malware. I have seen a TroJan and a backdoor Trojan in your logs- neither being something you want. I advise you to change your passwords and monitor the online financial transactions.

    I can't find any malware association with the [NetSoft]iexplore.exe entry. Netsoft is a Technology Search firm. Now if it is running using Internet Explorer and you are not aware of having this on the system, then maybe we should look into it. Malware can use the name of almost any process.

    You have IEv7, so you shold only have 1 iexplore.exe entry in the Task Manager-unless- you are not using the tab but launching IE again everytime you want another site- but that is user caused, not malware caused.

    Tmasgic cannot interpret the entries. He has asked you to remove 3 legitimate and needed entries- none of them should be removed.. An entry isn't removed because 'it looks suspecious'. It needs to be identified and then determined if it is a bad entry.

    I cannot identify any parts of this entry, so please do this:
    Please visit Jotti Online Malware Scan (
    Copy the following line into the white text box:
    Click Submit.
    Please post the results of this scan to this thread.
    Note: If the server is busy at the above site, try this alternative site:

    Go to Virus Total-Upload A File. (
    Copy the following line into the white text box:

    Then, we'll start over. And I ask that you please PASTE the HijackThis log. There is a reason for that.

    Other logs can be attached.

    I apologize- the problem might be do to my leaving out one direction. After the deletion from HijackThis, you should reboot back into Normal Mode, then run Combofix.

    Please do this: Click on Start> Run> type in ComboFix /Uninstall> enter. NOTE: there is a space between the x in fix and the /. It must be in there.

    When you have uninstalled it, Please reinstall according to instructions in Reply #6, then run the scan.

    See if this online scan works better:

    Please run an on-line virus scan at Kaspersky OnLine Scan or if that doesn't work, you can use TrendMicro or BitDefender. (Please post the results of the scan(s) in your next reply)

    If you are unable to run the activeX Antivirus Scanners, lets try this Java based solution from Trend Micro.

    When finished, attach the Combofix report and the Kaspersky log.

    Follow with rescan with HijackThis and paste in new log.

    Ah! We were posting at the same time! I was pretty sure it was malware- didn't know it was Heur. Isn't that an interesting process to identify an unknown?

    I tried to see if there was anyway to salvage my install but i thought better of it after still having the internet explorer problem of trying to connect to an address out there somewhere. Thanks for everyone's help but after reading some more things about the Heur and Virut viruses which I had, i thought a clean install was the safest bet. And again thanks for the suggestions and patience.

    Check this for Virut:

    • Make sure to use Internet Explorer for this
    • Please go to FREE on-line scan service
    • Copy and paste the following file path into the "Suspicious files to scan" box on the top of the page:
      • c:\windows\system32\userinit.exe
    • Click on the Upload button
    • If a pop-up appears saying the file has been scanned already, please select the ReScan button.
    • Once the Scan is completed, click on the "Copy to Clipboard" button. This will copy the link of the report into the Clipboard.
    • Paste the contents of the Clipboard in your next reply.
    Also scan these,

    • MVPS Hosts files This replaces your current HOSTS file with one containing well know ad sites etc. Basically, this prevents your computer from connecting to those sites by redirecting them to which is your local computer.
    • Google Toolbar Get the free google toolbar to help stop pop up windows.
