Yesterday I upgraded to the latest version of SpySweeper 5.0.5 The SpySweeper sweep says I have the Winlogonhook trojan. Removing it with SpySweeper does not get rid of it. I have gone to safe mode, deleted the WINDOWS/Prefetch folder, all temp folders, and temperory Internet files. The trojan is still there. Here is my Hijack This log run in safe mode.

Thanks for sending your information. We are sorry for the delay in responding. The volunteers here are swamped and unfortunately not all logs get answered as quickly as we'd like.

Please advise where SpySweeper says Winlogonhook trojan is located.

If you still need help with your problem, please run Hijack This again. Scan and copy the log, then post it here, in this topic . We do need to see a current logfile.

Please provide a description of the problem.

Please do not edit your Hijack This log. We need to see the entire logfile, with no revisions. If anything is disabled using MSCONFIG, please enable all, before scanning with Hijack This.

Please use the [external image: Posted Image] button to reply.

Thank you for your kind assistance. Because you were busy, after several days I went to the Lavasoft site and they were able to get the trojan off my system using HijackThis, Killbox, VUndofix, and DrWebCureIt. It took all four of those to do it. It appears that my system is now clean.

I'm glad you were able to find a solution to your problem.
Below, find some suggestions that I know will help. All these Programs are free.

One of the best features of Windows XP is the System Restore option, however if Malware infects a computer with this operating system the Malware can be backed up in the System Restore folder. Therefore, clearing the restore points is necessary after a virus removal.

To reset your restore points, please note that you will need to log into your computer with an account which has full administrator access. You will know if the account has administrator access because you will be able to see the System Restore tab. If the tab is missing, you are logged in under a limited account.

(winXP)

1. Turn off System Restore.
On the Desktop, right-click My Computer.
Click Properties.
Click the System Restore tab.
Check Turn off System Restore.
Click Apply, and then click OK.

2. Reboot.

3. Turn ON System Restore.
On the Desktop, right-click My Computer.
Click Properties.
Click the System Restore tab.
UN-Check *Turn off System Restore*.
Click Apply, and then click OK.

Here are some tips, to reduce the potential for spyware infection in the future, I strongly recommend installing the following applications:
  • Spywareblaster <= SpywareBlaster will prevent spyware from being installed.
  • Spywareguard <= SpywareGuard offers realtime protection from spyware installation attempts.

    Download the new Ad-Aware SE version, and follow the instructions on how to do a full scan: http://forums.spywareinfo.com/index.php?showtopic=11150
    -reboot after using Ad-Aware SE. Also while there get the VX2 plugin and follow the instructions to run it also.
  • How to use Spybot to remove Spyware <= If you suspect that you have spyware installed on your computer, here are instructions on how to download, install and then use Spybot. Similar to Ad-Aware, I strongly recommend both to catch most spyware.
To protect yourself further:
    MVPS Hosts file <= The MVPS Hosts file 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 127.0.0.1 which is your local computer
    Google Toolbar <= Get the free google toolbar to help stop pop up windows.

    * Clean your Cache and Cookies in IE:
    Close all instances of Outlook Express and Internet Explorer
    Go to Control Panel > Internet Options > General tab
    Click the "Delete Cookies" button
    Next to it, Click the "Delete Files" button
    When prompted, place a check in: "Delete all offline content", click OK

    * Clean your Cache and Cookies in Firefox (In case you also have Firefox installed):

    Go to Tools > Options.
    Click Privacy in the menu on the left side of the Options window.
    Click the Clear button located to the right of each option (History, Cookies, Cache).
    Click OK to close the Options window
    Alternatively, you can clear all information stored while browsing by clicking Clear All.
    A confirmation dialog box will be shown before clearing the information.
    * Clean other Temporary files + Recycle bin

    Go to start > run and type: cleanmgr and click ok.
    Let it scan your system for files to remove.
    Make sure Temporary Files, Temporary Internet Files, and Recycle Bin are the only things checked.
    Press OK to remove them.

    If you are not using an alternate browser to Internet Explorer, I suggest trying the Firefox browser. It is much safer than IE. Be sure to have a look at the Extensions available for it and get those you need, or want.
    Please use the following link to download the Firefox browser.
    http://www.mozilla.org/

    And also see TonyKlein's good advice
    http://castlecops.com/postlite7736-.html
    So how did I get infected in the first place?

    Safe surfing. :wavey:
