    Hi, everyone. I have something Malwarebytes calls Trojan.BHO that I can't seem to get rid of. Malwarebytes apparently gets it but it always ends up reappearing after a couple of reboots.

    I think it first showed up on the 14th of February during a routine checkup. It wasn't until after I tried to get rid of it that I started having problems.

    For wathever reason it wouldn't allow me to launch either Firefox or Chrome - in fact, the folders where they were installed were off-limits to all users, regardless of their admistrator status. I could temporarily gain control of the folders by running Malwarebytes and have since uninstalled both.

    I can still run IE, but -

    1. Whenever I try to open a link on a new tab, it will ALSO open a new window. Yes, I checked the settings, and it's definitely the trojan since this behaviour goes away - temporarily - after I run Malwarebytes.

    2. The Trojan also shows up as a toolbar add-on for IE ("jscript proxy auto-configuration"). It claims to be by "(unverified) Microsfot Corporation" and the option to disable it is greyed-out. The only way to get rid of it is to run Malwarebytes but, again, it comes back after a couple of reboots.

    3. It doesn't do anything else that's noticeable. There's nothing on my toolbar, no pop-ups, no redirecting, etc.

    If it matters, I have tried running Malwarebytes under safe mode after disabling system restore (that was following someone else's advice before finding this forum), but no cigar.

    And that's pretty much it. I can't tell when exactly the infection took place and I also don't remember visiting any fishy websites.

    Thank you for the help!

    Hi and welcome. :)

    Re run Hitman Pro and have it delete everything it finds.

    Delete these:
    • C:\Program Files (x86)\GUM4751.tmp
    • C:\Program Files (x86)\GUT4752.tmp


    [​IMG] Please download Junkware Removal Tool to your desktop.
    • Shut down your protection software now to avoid potential conflicts.
    • Run the tool by double-clicking it. If you are using Windows Vista or Seven, right-mouse click it and select Run as Administrator.
    • The tool will open and start scanning your system.
    • Please be patient as this can take a while to complete depending on your system's specifications.
    • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
    • Attach JRT.txt to your next message.



    Re run Malware Bytes and attach the new log.

    Now explain how things are.

    Hi!

    Sorry for not replying sooner, I thought it would be best to give it a couple of days. Several reboots later and nothing's popped up so I guess I'm in the clear. Thanks for the help, it was really appreciated :)

    Excellent. :)



    If you are not having any other malware problems, it is time to do our final steps:
    1. We recommend you keep Malwarebytes Anti-Malware for scanning/removal of malware.
    2. Renable your Disk Emulation software with Defogger if you had disabled it in step 4 of the READ & RUN ME.
    3. Go to add/remove programs and uninstall HijackThis. If you don't see it or it will not uninstall, don't worry about it. Just move on to the next step.
    4. If running Vista, Win 7 or Win 8, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    5. Now goto the C:\MGtools folder and find the MGclean.bat file. Double click ( if running Vista, Win7, or Win 8 Right Click and Run As Administrator ) on this file to run this cleanup program that will remove files and folders related to MGtools and some other items from our cleaning procedures.
    6. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.

    7. After doing the above, you should work thru the below link:
