Title: JS:Banker-IC help
Post by: dallasa on June 23, 2012, 05:45:13 AM
Hi,

Recently Avast has been giving me warnings that it has blocked a "JS:Banker-IC" trojan. This happens when opening any program (or even trying to do things such as update Avast or Firefox) or download any file. I don't remember opening anything or visiting any website that could have given me this, and Avast and Malwarebytes scans come up with nothing. I have no idea what to do or how dangerous this is to my online passwords. Help please?

Here are my Malwarebytes log, OTL log, and aswMBR log:

Is Avast still warning about this ?  If so what file does it reference
Title: Re: JS:Banker-IC help
Post by: dallasa on June 23, 2012, 08:17:43 PM
Yes it is. It references whatever file I'm running or trying to run at the time. Everything from the Avast updater to Firefox to Skype, etc. Sometimes it references a "wpad.dat".

Do you use a proxy to get online ?

run farbar service scanner (http://download.bleepingcomputer.com/farbar/FSS.exe)

(http://i1224.photobucket.com/albums/ee362/Essexboy3/Farbar/FSS-1.jpg)

Tick "All" options.
Press "Scan".
It will create a log (FSS.txt) in the same directory the tool is run.

Please copy and paste the log to your reply.

OK lets now delve really deep

Scanning with GMER

Before scanning, make sure all other running programs are closed and no other actions like a scheduled antivirus scan will occur while the scan is being performed. Do not use your computer for anything else during the scan.

(http://img.photobucket.com/albums/v666/sUBs/gmer_zip.gif)
Download GMER Rootkit Scanner from here (http://www.gmer.net/gmer.zip) or here (http://www.majorgeeks.com/download.php?det=5198).

Notes:
**Caution**
Rootkit scans often produce false positives. Do NOT take any action on any "<--- ROOKIT" entries 

-- If you encounter any problems, try running GMER in safe mode (http://www.computerhope.com/issues/chsafe.htm).
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

Here you go. Only hit is a videogame that I've had installed for months with no problem, so I'm assuming it's a false positive. Although Gmer would only let me scan for Services, Registry, and Files... all other boxes were untickable.

Post by: gpearson on June 23, 2012, 11:40:00 PM
Hello,

I too suddenly have this exact same problem. I have done a boot-time scan... Avast detects the virus but for some reason, it does not get deleted. When I start my PC Avast throws up the message...

A script started by c:\...\AvastUI.exe
JS:Banker-IC[Trj]
Process: c:\Program Files\...\AvastUI.exe

Sometimes when opening a browser the process is "AvastUI.exe".

I am fastidious about security & have no idea where this came from. My OS is Windows 7 & I use IE 8

Any insight would be sincerely appreciated.

Geoff Pearson

Post by: dallasa on June 24, 2012, 01:49:57 AM
If you've been fastidious too, perhaps it is a problem with Avast? I've certainly had no luck getting anywhere so far, although I will report back in once the Kaspersky scan is done (which will be a while, estimating 16 hours now).
Title: Re: JS:Banker-IC help

That has crossed my mind too. I might give Kaspersky a go overnight.

I am also suffering with the same JS:Banker-IC issue. I receive the warning message from Avast when I open IE(9), Skype and Avast.

Have run Avast virus scan and the boot time scan, which both claim to have deleted the virus, but it reappears.

I have also run MBAM and even installed Microsoft Security Essentials, both returned 0 infection results.

Please help as I am pulling my hair out here!

I am wondering whether this is a false positive, could you manually update the virus definitions and see if it still occurs
Title: Re: JS:Banker-IC help
Post by: dallasa on June 24, 2012, 09:02:35 PM
Kaspersky came up with nothing. All of my virus definitions are up to date so I can't manually update... I'll try uninstalling and reinstalling Avast in a bit and see what happens.
Title: Re: JS:Banker-IC help

Title: Re: JS:Banker-IC help
Post by: essexboy on June 24, 2012, 09:27:26 PM
I do not believe it to be a false positive now as I am getting no indication of this on either XP or 7

Is it on any specific page or any specific browser
Title: Re: JS:Banker-IC help
Post by: dallasa on June 24, 2012, 10:48:53 PM
Still getting the warnings after reinstalling. It isn't on any specific browser, both Firefox and Chrome bring up the warnings. The objects I've seen that bring up the warning are anything that requires a connection to the net (Firefox, Chrome, Skype, wpad.dat, avast.setup, etc.)

I'm thinking the same thing, see http://forum.avast.com/index.php?topic=100088.msg799230#msg799230 (http://forum.avast.com/index.php?topic=100088.msg799230#msg799230), my reply to a new topic started by pevans8180 in response to request by Pondus.

I have submitted it to avast for analysis.
Title: Re: JS:Banker-IC help
Post by: gpearson on June 25, 2012, 01:06:07 AM
I recall that that this started happening right after Avast did an automatic virus definition update. I don't have anything else does auto updates on my PC & I hadn't been doing anything out of the ordinary so... I wonder, could this be Avast itself that is corrupted?
Title: Re: JS:Banker-IC help
Post by: DavidR on June 25, 2012, 01:19:51 AM
Not corrupt as such, but a virus definitions update could have modified a signature that now detects a file as infected by JS:Banker-IC.

However, yours is slightly different different to this and the other topic as this was on a website file but same JS:Banker-IC signature, an update of this could have implications across many files.

Yours however, refers to a script
Quote from: gpearson
A script started by c:\...\AvastUI.exe
JS:Banker-IC[Trj]
Process: c:\Program Files\...\AvastUI.exe

Normally I would say that you should submit the file detected to avast for further analysis, but I don't see how you can send a script as there is no reference to the script, just the file starting it.

I should have been more clear earlier, but the same thing (getting a warning for a script) is also what's happening to me most of the time, with the .exe's (of Firefox, Avast, etc.) being the objects that start the script. The only warnings that aren't associated with a script seem to be for wpad.dat.

Hello,

I think Avast have fixed this issue, maybe in their latest virus definition updates. Problem was, if you already had the virus or whatever it was, the definitions couldn't update automatically because Avast itself was blocking the update when it detected the JS:Banker virus (falsely or otherwise). I basically just uninstalled Avast then downloaded the latest version & reinstalled. Everything appears to be normal again... at least so far!!

Title: Re: JS:Banker-IC help
Post by: DavidR on June 26, 2012, 01:36:57 PM
Personally I would stick with the analysis process, given that the avast labs have confirmed the detection is good.

Switching AV may well see a cessation of the alert, but that is no guarantee that it wasn't good and may leave you vulnerable.
Title: Re: JS:Banker-IC help
Post by: essexboy on June 26, 2012, 05:17:51 PM
That is correct, I am currently doing some research to find out where this could be running from

Switching to another AV will remove the alerts no problem... But then you are wide open to a dns changer malware

Post by: Mephitidae on July 01, 2012, 10:44:53 PM
the 'JS' of 'JS:Banker-IC' made me think that it was just that... a bit of javascript somewhere.... and i was right... a file named wpad.dat thats been sitting in IEs cache for over a year now containing nothing but a line of javascript....

so many applications claim to be 'running' it due to so many apps using the trident html rendering engine for their UI (such as avastui.exe and others) ... and of course it triggers when starting IE itself...

i just opened my computer > documents and settings > right clicked my user folder and clicked scan... it found the offending file... odd that the 'script shield' didnt know where it was.... seems avast needs to be a bit more... integrated...  ::)


so yeah... scan your user folder then send the offending one line file to the chest...


i archived it in a password protected rar... so if one of the higher ups here wants to see the offending code i still have it...

something funny going on here.... ....remove all those infected files and yet the script shield still goes off...

..first one is just wpad.dat ... then the hydra of the bunch is wpad[1].dat .... all clean.. right? nope...

more tempting to just disable the script shield than to wait who knows how long for all 1.4TB of hdd space in this machine to be fully scanned... esp since avast doesnt play well in 256mb of ram (its just a file server)...  >:(

if anyone with this script bug does a full scan and finds anything else dont hesitate to post...   :-\

Post by: gpearson on July 02, 2012, 12:55:55 AM
I'll second that comment about knowing where to start!

I have quite recently moved to Win 7 & I'm not a power user... I tried to follow the instructions but I don't see "Documents & Settings" on the Windows Start menu. I recall it was a standard feature on XP but unless I'm missing something, Win 7 is different.

In any case, I scanned the Windows folder on my "c" drive & sure enough, it picked up one infected file "wpad.dat". I did as instructed & moved it to the chest but... I still have the problem. I then cleared my IE8 cache but that didn't fix it. I then re-scanned the Windows folder with Avast & it reported zero infected files but... I'm still getting the Avast popup with "wpad.dat" as the culprit.

Seems that maybe I looked in the wrong place... any ideas?

ive found it, complete with url from which its downloaded, in the registry... dunno if deleting those keys would be a good idea or not tho...
Hi Mephitidae,

Perhaps a better idea would be to post the registry lines here so essexboy can have a look for it.  We are all numpties when something new like this comes along... best to wait on these registry references....

...Once you have 20 or more posts here, then you can pm....

well... thats just it... i had a mindset of 'im just going to reinstall anyway so what the heck' when i did what i did so i didnt care if i broke things... fortunately i didnt and fixed it instead... i didnt keep a record of the registry lines... but they may be in the backup data... ...registry tricks arent what solved it tho and thats where the slide in sideways part comes in...

Having gone this far it would best followed through, that way it would have helped you, but importantly give essexboy information to help others in this position.

I think he feels like I do a reformat and reinstall (nuclear option) is one of last resort.

Post by: Mephitidae on July 02, 2012, 04:32:54 PM
false alarm.... didnt get rid of it.... only blocked it for a single reboot and then it came back.... even tho there is nothing in the registry that references the url its downloaded from....

-- edit

i cant change the homepage IE is set to either... so something is most likely hidden in gpedit.msc .... yay...

--edit again

something is rewriting it ... its being stored in HKU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections among other places...  ... mentions a malformed url http://wpad/wpad.dat ...

I believe that I have found the common denominator now... Took some reading but fingers crossed

Warning This fix is only relevant for this system and no other, using on another computer may cause problems

Be advised that when the fix commences it will shut down all running processes and you may lose the desktop and icons, they will return on reboot

Run OTL
Title: Re: JS:Banker-IC help
Post by: Mephitidae on July 02, 2012, 07:52:21 PM
that caused a hard freeze when it wanted to reboot but i reset the machine and it continued...

heres the log file....


oddest part about this log is that opera java and flash were uninstalled quite some time ago..

--edit

didnt clean the virus out either... it still re-downloaded
Title: Re: JS:Banker-IC help
Post by: essexboy on July 02, 2012, 07:55:37 PM
Have the alerts ceased ?   Also could you run a quick scan so that I can check the TCPIP
Title: Re: JS:Banker-IC help
Post by: essexboy on July 02, 2012, 07:57:07 PM
OK just seen that could you run this MSFixit prior to the OTL scan please http://support.microsoft.com/kb/299357

OK next question, are any other computers using the same router as you ?  If so do they get the same alerts
Title: Re: JS:Banker-IC help
Post by: boyboy88 on July 02, 2012, 08:50:08 PM
Just want to share my experience, I've this problem for a week and I had used the Malwarewbytes and Kaspersky to scan my computer, no virus or malware could be found.
But when I bypass my router(running TomatoVPN), ie. direct connect my computer to the ISP, no JS:Banker-IC alert appears from Avast.   However, once I connect back the router, the alert comes back.

Cheers.
Title: Re: JS:Banker-IC help
Post by: essexboy on July 02, 2012, 08:52:28 PM
So a router infection is your experience ?
Title: Re: JS:Banker-IC help
Post by: boyboy88 on July 02, 2012, 08:55:57 PM
Other computers on the same router have the same alert with Avast but not on the computer just with Microsoft Security Essential.
Title: Re: JS:Banker-IC help
Post by: essexboy on July 02, 2012, 08:56:36 PM
Have you reset the router and changed the password ?
Title: Re: JS:Banker-IC help
Post by: Mephitidae on July 02, 2012, 08:58:49 PM
quick scan is what gets stuck... i dont have enough ram on that system...


as for other computers on the same router the other (windows) machine doesnt have any alerts and does have avast so its not spread over the lan on mine...
Title: Re: JS:Banker-IC help
Post by: dallasa on July 02, 2012, 09:02:34 PM
The other computer using the router isn't receiving any alerts, however it is a Mac. I will test a couple other Windows machines later today.

Go to Control Panel > Network Connections
Right click the current network and selecect properties
Select IPV4 and select properties
On the general tab are the settings the same as mine

Everything's still clear after rebooting. Fingers crossed that it stays that way, and if so that seems like a simple solution after all that trouble  :D
Title: Re: JS:Banker-IC help
Post by: essexboy on July 02, 2012, 11:21:06 PM
It actually appears that a two pronged approach is needed

First to remove the TCPIP domain and then clear the DCHP

I will now go and try that with the rest  ;D

Post by: essexboy on July 02, 2012, 11:53:47 PM
This is not really anything to do with a local area networks, it relates to how the dns server is set up on each individual computer when it connects to the net and whether it uses a dynamic or static address
Title: Re: JS:Banker-IC help
Post by: Mephitidae on July 03, 2012, 12:01:33 AM
so on a machine with a static manually assigned ip/dns this virus does nothing? even if still present?

Post by: DavidR on July 03, 2012, 12:04:13 AM
DCHP is enabled by default on Vista and 7 but I am not overly sure about XP ...  Need to check that out

The DHCP service  is started Automatically on my XP Pro SP3, certainly don't recall ever setting it to Automatic, I'm usually the revers in either disabling or setting services I don't need (blackviper) to manual just in case.

I don't have a local network setup, though I have two computers they aren't networked, my second connects by WiFi to my router.
Title: Re: JS:Banker-IC help

Very recent XP install shows the service as automatic so I would say it is set that way by default.

Nope I will just remove all the tools that you have downloaded  ;D

Subject to no further problems   :)

I will remove my tools now and give some recommendations, but, I would like you to run for 24 hours or so and come back if you have any problems 

Now the best part of the day ----- Your log now appears clean  :thumbsup:

A good workman always cleans up after himself so..The following will implement some cleanup procedures as well as reset  System Restore points:

Run OTLRemove ComboFix

Run OTL and hit the cleanup button.  It will remove all the programmes we have used plus itself. 

We will now confirm that your hidden files are set to that, as some of the tools I use will change that

Hello All,

I tried this fix but, I still have this problem on my Win 7 Professional PC. I am not an OS or Internet wizard & I'm confused but. Can anyone tell me...

1) Is this actually a virus?

2) If affirmative, what exactly is the perceived threat?

3) How come only Avast is affected? ie. is it an Avast problem?

4) How come none of the other AV scans pick it up?

5) Would it be a safe assumption that if I change my AV program to say... Norton, I would be just as well protected as any other Norton user?

Any insight appreciated.

Hi gpearson,

As this infection was new to essexboy and others,it did take a little more time to get a successful repair and fix here.

As for point #5, at the time this thread was started, only Avast! was able to detect this infection.  You can, of course, remove Avast!, and thus not get alerts anymore, but the infection will still remain on your system.  I would choose to get the infection cleared first, and then go and get another a/v if that is what I thought was best.

If you wish to get help here for this, please start your own topic in this section by going to "New Topic" button upper right.  Please see and read http://forum.avast.com/index.php?topic=53253.0 (http://forum.avast.com/index.php?topic=53253.0) and attach all logs produced by Malwarebytes, OTL, and aswMBR in your new topic.

As malware is changed, in some cases almost hourly, this infection may not be exactly the same as the one essexboy dealt with here, and thus the repair may/may not work for you.  Fixes made by essexboy and others are always custom-made only for the system affected; attempting to repair using the custom fix can damage your system.

Once the logs are posted, please do not make any changes to your system other than those requested by the malware expert assisting you.  This will make cleaning and repairing your system much easier, and at far lower risk of system damage than otherwise.
