Help deleting malware files

KurtS · February 19, 2014

I picked up malware from the CNET downloader (arghh).

Malwarebytes is having problems removing a folder and 2 files in it.

Folder is boost_interprocess and files are:

Nobu64AgentService

Nobu64TrayIcon

Looks like they did a really good job blocking me from getting to these files.

I get File Access Denied when I try and delete them.

It won't let me view the permissions of the files to change them.

It said I couldn't change the security permissions, but it actually did. But no effect. I have the full control both as admin and as user and I can't get past the Folder/File Access Denied.

I tried a file unlocker and it says the files are unlocked and it fails to delete them.

Any ideas? Using WIN8, btw.

Thanks!

I would not agree with that blanket statement. It wasn't the software that had malware, but the delivery vehicle.

That link doesn't help me with my specific problem.

Please post back the MBAM log file for review.

STEP 0
RKill is a program that was developed at BleepingComputer.com that attempts to terminate known malware processes
so that your normal security software can then run and clean your computer of infections.
When RKill runs it will kill malware processes and then removes incorrect executable associations and fixes policies
that stop us from using certain tools. When finished it will display a log file that shows the processes that were
terminated while the program was running.

As RKill only terminates a program's running process, and does not delete any files, after running it you should not reboot
your computer as any malware processes that are configured to start automatically will just be started again.
Instead, after running RKill you should immediately scan your computer using the requested scans I've included.

Please download Rkill by Grinler from one of the links below and save it to your desktop.

Link 1
Link 2

On Windows XP double-click on the Rkill desktop icon to run the tool.
On Windows Vista/Windows 7 or 8, right-click on the Rkill desktop icon and select Run As Administrator
A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
If not, delete the file, then download and use the one provided in Link 2.
If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
If the tool does not run from any of the links provided, please let me know.
Do not reboot the computer, you will need to run the application again.

STEP 01
Backup the Registry:
Modifying the Registry can create unforeseen problems, so it always wise to create a backup before doing so.

Please download ERUNT from one of the following links: Link1 | Link2 | Link3
ERUNT (Emergency Recovery Utility NT) is a free program that allows you to keep a complete backup of your registry and restore it when needed.
Double click on erunt-setup.exe to Install ERUNT by following the prompts.
NOTE: Do not choose to allow ERUNT to add an Entry to the Startup folder. Click NO.
Start ERUNT either by double clicking on the desktop icon or choosing to start the program at the end of the setup process.
Choose a location for the backup.
- Note: the default location is C:\Windows\ERDNT which is acceptable.
Make sure that at least the first two check boxes are selected.
Click on OK
Then click on YES to create the folder.
Note: if it is necessary to restore the registry, open the backup folder and start ERDNT.exe

STEP 02
Please download RogueKiller and save it to your desktop.

You can check here if you're not sure if your computer is 32-bit or 64-bit

RogueKiller 32-bit | RogueKiller 64-bit
Quit all running programs.
For Windows XP, double-click to start.
For Vista,Windows 7/8, Right-click on the program and select Run as Administrator to start and when prompted allow it to run.
Read and accept the EULA (End User Licene Agreement)
Click Scan to scan the system.
When the scan completes Close the program > Don't Fix anything!
Don't run any other options, they're not all bad!!
Post back the report which should be located on your desktop.

I have rebooted, rescanned, and that was the log that I posted. The first time thru it found 20 or so files. Just those 3 remain and they have the permissions screwed around such that I can't delete them, nor can MWB.

I'll update soon.

Thanks!
