Downloader.misleadapp Virus - Can't remove...

My laptop (running Vista) has been infected with a downloader.misleadapp virus and nothing I've tried to remove it is working.  First, ran liveupdate and tried to scan, but Norton IS09 can't get past "initializing".  Ran update then tried a full scan in safe mode.  Norton scans maybe 1% of my total files then says its complete and finds nothing.  Tried running Malwarebyetes Anti-Malware but it won't load.

I certainly appreciate any and all help.  Thanks!

Hi zrelaxed,

Try renaming mbam.exe (Malwarebytes) to something else such as road.exe and see if it will run. If you can get Malwarebytes to run, please post the scan results log here.

If Malwrebytes does not solve your issue you may have to generate a HijackThis log and post the log here.

Here is a link to download the HijackThis utility and there is also a video tutorial on the page.

Please just generate the log and do not attempt any repairs until one of our knowledgeable members can review it.

Please also download and run GMER. Post the log over here.

I assume you mean re-naming and not renaming?  And re-naming it "mbam.exe" will not work as Attackers have started to Target Malwarebytes' Anti-Malware, which is why Phil suggest "road.exe".

Re: Downloader.misleadapp Virus - Can't remove...

We have found in some cases the name change has to occur as early as the download screen, where you have to change the download to "Save as" in order for it to be allowed onto the machine.  When it installs, go into the program and change that .exe to the same name or it might not be able to run.

Re: Downloader.misleadapp Virus - Can't remove...

First - Thank you Everyone!  I sincerely appreciate your help.  Renaming the mbam.exe file worked like a charm.

Below are the results from the Malwarebytes scan.  I'll run the gmer scan tonight.

Re: Downloader.misleadapp Virus - Can't remove...


We will definitely require the GMER.  Scan only, do nothing to resolve anything using GMER.  It can cause considerable issues if not used properly.  We only need it to identify all the files which are associated to your gxvxc rootkit.  The log can be posted in segments, try to keep them in order, and plug them all in for Quads to look at later.

Thanks Zrelaxed.  Nice work.  Quads will be along later.  We have time zone issues.  He will provide tools and instructions later in the day.

Sounds great.  Again, your help is much appreciated.  If there's anything else I can do in the interim, just let me know.

Now  (read carefully) If you have Spybot S&D uninstall it.

1. Download Avenger to your desktop,

Unzipped version http://homepages.slingshot.co.nz/~crutches/Avenger/

Creators website http://swandog46.geekstogo.com/avenger2/avenger2.html with zipped version to the unzip to desktop 

2. Click to run "Avenger.exe"  (right click "Run as Administrator" if using Vista)

3. In the "Input script here:" copy and paste the script between the lines

Drivers to disable:



Drivers to delete:



Files to delete:







Folders to delete:







Registry keys to delete:













Here is a screenshot (script updated since shot)

Make sure the "Automatically disable any rootkits found" is NOT selected

4. Click "Execute"

You will be asked to restart the PC click "Yes", when the PC restarts the load screen will takes slightly longer, then when it looks as though windows is loading the PC will restart again.

Then when Windows fully loads the Avenger log will be loaded, showing files it could or could not find.

5. This Rootkit can come with a DNS Changer

Restart the PC again, then see if you can install  Update and run Malwarebytes From http://www.malwarebytes.org/mbam.php  or http://www.filehippo.com/download_malwarebytes_anti_malware/

After Run a Full Scan, then if it finds anything remove them, then see if you can update Malwarebytes 



Re: Downloader.misleadapp Virus - Can't remove...

Thank you!  As far as I can tell, your solution worked perfectly.  Just updating NIS09 and running a full scan to confirm.  I sincerely appreciate everyone's help.

You will be able to see in the Avenger log what was removed by Avenger.
