Heur AVG and a strange .exe in prefetch.

[Threatened]

Hi there, new here and hoping for some assistance.

I recently had a heur virus show up in my AVG Scans...after a few scans it dissapeared to the virus vault, but at the same time I noticed a new process running under BA0F49.EXE

I can't find any reference info on the nature of this file online, so dont know if I should be suspicious of it.

The only searchable reference to it is in the windows prefetch folder with file name...BA0F49.EXE-0585C7DD.pf

I think this is where it is being loaded from?? When it is busy the file seems to eat roughly 7k worth of resources, but no idea what its up to.

Any advice appreciated.

Thanks

Update: Ran a hjt scan with the result below. Is BA0F49.EXE a problem?

Delete any existing version of ComboFix you have sitting on your desktop

Please read and follow all these instructions very carefully

Download ComboFix from Here to your Desktop.

**Note:  It is important that it is saved directly to your desktop  and run from the desktop and not any other folder on your computer**
--------------------------------------------------------------------
1. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

• Very Important! Temporarily disable your anti-virus and  anti-malware real-time protection and any script blocking components of them or your firewall before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results" or stop combofix running at all
• Click on THIS LINK to see instructions on how to temporarily disable many security programs while running combofix. The list does not cover every program. If yours is not listed and you don't know how to disable it, please ask.
  
• Remember to re enable the protection again after combofix has finished
  

--------------------------------------------------------------------
2. Close any open browsers and any other programs you might have running

Double click on combofix.exe & follow the prompts.

If you are using windows XP It might display a pop up saying that "Recovery console is not installed, do you want to install?"
Please select yes & let it download the files it needs to do this
When finished, it will produce a report for you. 
Please post the "C:\ComboFix.txt" for further review


****Note: Do not mouseclick combofix's window while it's running. That may cause it to stall or freeze ****

Note: ComboFix may reset a number of Internet Explorer's settings, including making it the default browser.
Note: Combofix prevents autorun of ALL CDs, floppies and USB devices to assist with malware removal & increase security. If this is an issue or makes it difficult for you -- please tell us when you reply. Read HERE why we disable autoruns

Please do not install any new programs or update anything unless told to do so while we are fixing your problem.

Hi Derek

Thanks for having a look at this for me.

I have run combo fix twice, with both logs attached.

1st was run with out recovery console.
comfix2 was run with recovery console.

I have tried and tried but AVG version 9.0.709 (free) will not allow me to disable it. I got a couple of warnings from combo fix but proceeded anyway.

Please let me know what next, I noted that I did not see any mention of the BA0F49.EXE file in the file.

Thanks again.

Download the attached CFScript.txt  and save it to your  desktop ( click on the link underneath this post & if you are using internet explorer when the "File download" pop up comes press SAVE and choose desktop  in the list of selections in that window & press save)

Disable any antivirus/antimalware/firewall realtime protection or script blocking in the same way you did previously before running combofix & remember to re-enable it when it has finished

Close any open browsers
Then drag the CFScript.txt into the ComboFix.exe as shown in the screenshot below.

 



 

This will start ComboFix again.  It may ask to reboot.  Post the contents of Combofix.txt in your next reply .

Hi Derek,

Result log attached, a couple of notes...

1) combofix wanted to update latest update...would this have affted the running of it via the cfscript?
2) on restart file catchme.cfxe came up with a warning that it was not closing properly.

Thanks again for your help!

This will create a zip file inside C:\QooBox\quarantine named something like  [38]-Submit_2008-01-17@17.50.zip 

at the end it will pop up an alert  & open your browser and  ask you to send the zip file

please follow those instructions. We need to see the zip file before we can carry on with the fix

If there is no pop up alert or open browser then

please go to  http://www.thespykiller.co.uk/index.php?board=1.0 and upload these files so I can examine them and if needed distribute them to antivirus companies.
Just press new topic, fill in the needed details and just give a link to your post here & then press the browse button and then navigate to & select the files on your computer, If there is more than 1 file then press the more attachments button for each extra file and browse and select etc and then when all the files are listed in the windows press send to  upload the files ( do not post HJT logs there as they will not get dealt with)

Files to submit:
the zip file  inside C:\QooBox\quarantine created by combofix named something like  [38]-Submit_2008-01-17@17.50.zip 

or to

Hi Derek,

It looks like the upload was successful. See attached log.

Thanks also for the insight..

[Derek]

looks like we got it all

how are things now

* Run Kaspersky online virus scan  Kaspersky Online Scanner.

After the updates have downloaded, click on the "Scan Settings" button.
select the (b)"Spyware, Adware, Dialers and other potentially dangerous programs" for the scan.
Under "Please select a target to scan", click "My Computer".
When the scan is finished, Save the results from the scan!

Note: Kavscan is a scanner only & won't fix anything but will normally find the most infected files so it's report gives us a good place to work from

If that won't run then
Run an online antivirus check from one of the following sites
http://security.symantec.com/default.asp?
http://housecall.trendmicro.com/
http://www.pandasoftware.com/activescan/
http://www.bitdefender.com/scan8/ie.html

Hi Derek.

I have run Kasp scan twice now, initially against thecritical areas, and today against my computer.

I have attached the log, it is identifying only one infected file, which happens to be ComboFix.exe

Sorry its taken me a while to get back, was a busy weekend.

Regards

[Derek]

should be fine now then

*Follow these steps to uninstall Combofix and the other tools it downloaded to remove the malware*
*  Click START then RUN
*  Now type Combofix /Uninstall in the runbox  and click OK.  Note the space between the X and the /U, it needs to be there.


This will also purge the restore folder and clear any malware that has been put in there. Now Empty Recycle bin on desktop Then reboot.

go here http://www.thespykiller.co.uk/index.php?page=3 for info on how to tighten your security settings and how to help prevent future attacks.

and scan here http://secunia.com/software_inspector/ for out of date & vulnerable common applications on your computer and update whatever it suggests

Then pay an urgent visit to windows update & make sure you are fully updated,  that will help to plug the security holes that let these pests on in the first place

Modern Malware has become so involved and difficult to fix that it takes a very long time and a lot of hard work to read all the logs posted here and research and prepare the fixes for you.
