Bube.d (aka Win32.Beavis) Removal

Bube.d aka Win32.Beavis is a new infection. The only program I have found so far that removes it properly is KAV Personal 5.0 (you can get a free 30 day trial, fully functional that will remove it for you). We have found a number of AVs detect and claim to cure it but instead, they quarantine and/or delete the infected explorer.exe leaving you with no desktop.

This infection can download over 100 different malwares, but some typical entries you might see in a log look like this (and after cleaning offline, they come right back as soon as you connect to the internet)

The file infecting AdWare saga continues
Roel February 10, 2005 | 15:28 MSK

comment
We are currently seeing an increase in cases which involve file infecting AdWare.

These new viruses are more sophisticated than the one we previously reported and append malicious code to Windows' explorer.exe. The viruses belong to the Virus.Win32.Bube family.

For example, Virus.Win32.Bube.d downloads AdWare and Trojans, including: AdWare.ISearch.d, Trojan-Clicker.Win32.Agent.bn, Trojan.Win32.LowZones.ai and PornWare.Dialer.Salc.

Disinfection in this case is tricky, as explorer.exe is an important Windows process. Additionally, the malware tries to prevent removal by disabling system restore, infecting the explorer.exe residing in %sysdir%\dllcache and lowering overall system security.

Things can get extra complicated as an AV can block access to the infected explorer.exe.

We are finding that some users are blocked from the KAV site due to changes in the HOSTS file. If you cannot get to the download link provided or are having trouble updating KAV, please try the following:

Download the Hoster from here: http://www.funkytoad.com/download/hoster.zip
Press 'Restore Original Hosts' and press 'OK'
Exit Program.
Note: if you were using a custom Hosts file you will need to replace any of those entries yourself
You must get the updates before scanning. Detailed instructions for updating are below.

Go here to download the free KAV Personal 5.0 Trial (good for 30 days)
http://www.kaspersky.com/index.html

Click on *downloads* on the left menu

Then scroll down and click on *trial versions*

Then choose *Kaspersky Anti-Virus Personal 5.0*

You will then have a list of the trial downloads to choose from (choose a location closest to you)

Choose *save* and it should create and save to a KAV folder on your hard drive

Navigate to the KAV folder and doubleclick on kav5.0trial_personalen.exe to install it.

You will see this screen showing the default folder it will install into. Click on *next*

If KAV detects another AV running on your PC it will advise you to uninstall it.
You can do that or you can disable the existing AV program and then press *yes* to continue.
The way to disable resident protection differs for different anti-virus programs. You might try right clicking on the icon for your AV program in the Windows System tray (on the lower right hand part of the screen) and looking at the different options.
Alternatively, you may disable your AV from starting with Windows using msconfig (Start > Run and type msconfig and OK. Click on the Startup Tab, uncheck all the startups relating to your AntiVirus and reboot).
The important thing is to set your current AV *not* to scan as your files are accessed, so that KAV can do its job

In my case, I just disabled the resident protection on EZ AV and that worked just fine without uninstalling it.

Next you will see the Kaspersky Anti-Virus Personal 5.0 Setup Wizard. It will advise you to close all other applications before starting setup. Do that and then press *Next* to continue.

You will then be presented with the License Agreement. Read that and when done you can agree to continue.

Next is the Customer Information screen. Just fill that in as you prefer and click on *next* to continue

You will be presented with some important KAV notes. I copied these and saved in Wordpad to refer back to if needed.

Please remove the green checkmark the box that says *Operate according to Recommended settings* This is so we can do a custom install.

Press *next* to continue after you have read those and unchecked the box for recommended settings

On the next screen, please uncheck the box for *use real-time protection against network attacks*
This has been known to cause problems on PCs running certain firewalls, you can try enabling it later after the initial install and scan.

You may leave the *iStreams technology* box checked if you like (I did) but it is generally recommended not to checkmark that box if you are going to uninstall KAV again after the infection has been removed.

Now it will choose the Destination folder (mine was fine as pre-selected by KAV). Click *next* to continue

Now you will get the *finish* screen

KAV will now open. If you are running a firewall, allow KAV to connect to get the updates it needs. Wait while the updates are downloaded and installed

Now get the *extended database* of updates as well, to remove the AdWare that Virus.Win32.Bube. may have downloaded. Look under *Settings*, and then *Configure Updater* Choose Extended Database. Click *OK* and then Check for Updates and you will get another smaller update which will install.

Now click on *Settings* and choose *Configure On-demand scan settings* and select *Perform recommended action* and click *OK*. You might prefer to set the scan level to maximum, just to be sure that nothing is hiding in an email database.

After clearing the HOSTS file with Hoster, if you still cannot connect to the internet to get the updates on an infected PC, follow the steps below. Otherwise please proceed to the Scanning Section

MANUALLY UPDATING

You will need access to another computer. If you don't have one, perhaps a friend can help, ask your boss if you can use a work computer, go to a Kinkos or the public library.

Go here http://www.kaspersky.com/avupdates

Download the complete update... a 4.9MB zip. Choose *Complete update* (cumul.zip)

Then, on the next page under *complete update*, choose the server closest to you for the download.

After downloading, burn it to a CD and copy the zip from the CD

Save it to C:\Documents and Settings\All Users\Documents\Kaspersky Anti-Virus Personal Updates unzip it

Go to C:\Documents and Settings\All Users\Application Data\Kaspersky Anti-Virus Personal\5.0\bases "delete everything there" you won't be able to delete one of the files don't worry it will get overwritten*

Open the Kaspersky Program ,open the settings tab,then open configure updater,go to update type and select from a local folder click browse (the ... button, see example in image) and find the folder where you unzipped the files select it and exit.

Go back into kaspersky and click Update Now you should see the files load in really fast and it will update.

A simpler method which worked for me...(EDIT: I did this with KAV running. It might be safer to exit KAV while manually updating with this method so none of the files are in use when you overwrite.)

save the zip to your desktop. I unzipped to the default Winzip location c\unzipped. Navigate to that folder and open the file. Click edit/select all. On the left hand side click Copy or move selected items. Copy or move the items here: C:\Documents and Settings\All Users\Application Data\Kaspersky Anti-Virus Personal\5.0\bases and copy or move the new database. You will get a window that says a file already exists. Do you wish to overwrite? Click yes to all and you have the latest definitions.:)

On reboot you may or may not get an error message saying your database is corrupt and to reinstall the program. Ignore it. You are good and when you are able to auto-update, it will correct itself.

SCANNING INSTRUCTIONS

Close KAV and any open programs you have running.

It is recommended you run the scan in SAFE MODE
Initiate your scan. (see instructions below on scanning first!)

* Boot into safe mode.
How to start the computer in Safe mode (here are instructions if you need them)
http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001052409420406?OpenDocument&src=sec_doc_nam
Once you have booted into safe mode as XP can still allow an internet connection in safe mode

Physically Disconnect from the Internet

* Open KAV but do not start the scan yet

* now and this is very important :

* Press Ctrl + ALT+DEL and bring up task manager, go to processes tab and right click on explorer.exe and then select stop process

Now your desktop will go blank and you will have no taskbar or menu etc you will still have taskmanager and KAV open on desktop so do not close them

* Now Start a full system scan. Click on the protection tab and Choose *Scan My Computer
* It will take some time probably 2 or 3 hours and will delete any infected files it finds
* KAV will disinfect all files detected as Virus.Win32.Bube and many related malware it has downloaded.
* when it has finished then on the Taskmanger press file/newtask and type explorer to regain the desktop etc.
* Close KAV &Taskmanager
* Reboot back into normal mode.

Additional cleanup may be needed. Please be sure to post in the forum if you have any questions.

IMPORTANT NOTE! This virus changes security settings your trusted zone and in the Windows Security Center. Please be sure to check all of your security settings After disinfecting.
................................
If you are asked to post a KAV log from your scan. Here's how:

Click on *View Reports*

When you go to View reports, you will see a list. You rightclick on the report *Full Scan* and a menu opens: choose *export detailed report to file* which allows you to save it

It defaults as a .csv file, but I found I could save as .txt. Give it a name and click *save* to save the log.

Then you can attach your report to a reply for review.

New Development {25 Mar 2005}!

KAV does clean most of the infection but does not fix the registry settings that were changed by the Bube trojan (and it's accompanying multiple spyware infections) that lower many security settings on the victim's PC.

I asked Microsoft to look into the Bube infections and the security settings particularly. They have been studying the different variants and the settings that are changed. I got an email this morning from them.

I have been notified by the Microsoft Services and Field Security Support Team that the current signatures for the Microsoft Antispyware software will remove all variants thru Bube.E currently and put the WU and IE Zone settings back to default. They are working on further variants, so updating the definitions is critical.

Microsoft Antispyware Beta1 is free and available for Microsoft Windows 2000, Windows XP, or Windows Server™ 2003

You can get the download here:
http://www.microsoft.com/athome/security/spyware/software/default.mspx

Be SURE to get the latest updates for the program (just open the program and Click on the *Spyware Definitions* to update the program before scanning)
