Computer under attack - please help


Recommended Posts

Have the dreaded dllhost.exe *32 issue (COM Surrogate) listed in the task manager.  Even if I try and kill them, they come back.  Computer is running very slow and every once in awhile the screen just goes dark and I have to rebot.

 

I tried to download the malwarebytes program but it will not run.  Tried the chameleon and it also would not run (get some kind of internet explorer script error and ActiveX). 

 

After awhile I start getting program errors as well - will not let me view folders, run programs, etc. as it states you do not have permission. 

 

I have read a few of the forums in here, but do not want to start any process until someone with 'expert' knowledge would be willing to help.

 

Many Thanks!

Update:

 

tried to run Malwarebytes anti-malware program and still will not run.

 

Downloaded the farber recovery scan tool. when I select run I get the following error message:

"Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."

 

Any idea on how I can get the Farber scan tool to work so I can get the .txt files to see what is going on?

Next,

 

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into.

NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

 

Run FRST and press the Fix button just once and wait.

The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

 

Next,

 

Boot back to normal mode and run the following:

 

Download RKill from here: http://www.bleepingcomputer.com/download/rkill/

 

There are three buttons to choose from with different names on, select the first one and save it to your desktop.

 


Double-click on the Rkill desktop icon to run the tool.
If using Vista or Windows 7/8, right-click on it and Run As Administrator.
A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
A log pops up at the end of the run. This log file is located at C:\rkill.log. Please post this in your next reply.
If you do not see the black box flash on the screen delete the icon from the desktop and go back to the link for the download, select the next button and try to run the tool again, continue to repeat this process using the remaining buttons until the tool runs. You will find further links if you scroll down the page with other names, try them one at a time.
If the tool does not run from any of the links provided, please let me know.

 

Next,

 

Read the following link before we continue and run Combofix:

ComboFix usage, Questions, Help? - Look here

Next,

Delete any versions of Combofix that you may have on your Desktop, download a fresh copy from either of the following links :-

http://download.bleepingcomputer.com/sUBs/ComboFix.exe

http://www.infospyware.net/antimalware/combofix/

  • Ensure that Combofix is saved directly to the Desktop <--- Very important
  • Disable all security programs as they will have a negative effect on Combofix, instructions available here  http://www.bleepingcomputer.com/forums/topic114351.html if required. Be aware the list may not have all programs listed, if you need more help please ask.
  • Close any open browsers and any other programs you might have running
  • Double click the combofix.gif icon to run the tool (Vista or Windows 7 users right click and select "Run as Administrator)
  • Instructions for running Combofix available here http://www.bleepingcomputer.com/combofix/how-to-use-combofix if required.
  • 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. Once the recovery console is installed Combofix will then offer to scan for malware. Select continue or yes.
  • 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  http://thespykiller.co.uk/index.php?page=20 why  disabling autoruns is recommended.

*EXTRA NOTES*


  •    
  • If Combofix detects any Rootkit/Bootkit activity on your system it will give a warning and prompt for a reboot, you must allow it to do so.
       
  • If Combofix reboot's due to a rootkit, the screen may stay black for several minutes on reboot, this is normal
       
  • If after running Combofix you receive any type of warning message about registry key's being listed for deletion when trying to open certain items, reboot the system and this will fix the issue (Those items will not be deleted)



Post the log in next reply please...

Thanks for the logs, continue as follows please:

 

1. Close any open browsers.

2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

3. Open notepad and copy/paste the text in the Codebox below into it:

ClearJavaCache::Registry::[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run]"UpdReg"=-File::c:\windows\UpdReg.EXE

Save this as CFScript.txt, and as Type: All Files (*.*) in the same location as ComboFix.exe

CF3.jpg

CFScriptB-4.gif

Refering to the picture above, drag CFScript into ComboFix.exe

When finished, it shall produce a log for you at C:\ComboFix.txt which I will require in your next reply.

 

Next,

 

We still need to run an online AV scan to ensure there are no remnants of any infection left on your system that may have been missed. This scan is very thorough and well worth running, it can take several hours please be patient and let it complete:

 

Run Eset Online Scanner

 

**Note** You will need to use Internet explorer for this scan - Vista and Windows 7/8 right click on IE shortcut and run as admin.

 

(To run ESET Online Scanner in a browser other than Internet Explorer, you'll need to download ESET SMART  Installer during the process)

 

Go to Eset web page http://www.eset.com/us/online-scanner/ to run an online scan from ESET.

 


Turn off the real time scanner of any existing antivirus program while performing the online scan
click on the Run ESET Online Scanner button
Tick the box next to YES, I accept the Terms of Use.
Click Start
When asked, allow the add/on to be installed
Click Start
Make sure that the option "Remove found threats"  is UNticked
Click on Advanced Settings, ensure the following options are checked:
 
Scan for potentially unsafe applications
Enable Anti-Stealth Technology
 
Click Scan
wait for the virus definitions to be downloaded
Wait for the scan to finish

 

When the scan is complete

 


If no threats were found
put a checkmark in "Uninstall application on close"
close program
report to me that nothing was found

 

If threats were found

 


click on "list of threats found"
click on "export to text file" and save it as ESET SCAN and save to the desktop
Click on back
put a checkmark in "Uninstall application on close"
click on finish

 

close program

 

Copy and paste the report in next reply.

 

Next,

 

Download Security Check by screen317 from either of the following:

http://screen317.spywareinfoforum.org/SecurityCheck.exe or http://screen317.changelog.fr/SecurityCheck.exe

Save it to your Desktop. (If your security alerts either accept the alert, or turn the security off while Secuirity Check runs)
Double click SecurityCheck.exe (Vista or Windows 7/8 users right click and select "Run as Administrator") and follow the onscreen instructions inside of the black box. Press any key when asked.
A Notepad document should open automatically called checkup.txt; please post the contents of that document.

If Security Check will not run or you get an alert saying it is not supported, Re-boot your PC then try again...

 

Let me see those logs, also give an update on any remaining issues or concerns...

 

Thanks,

 

Kevin...

Kevin,

 

Here are the latest files.

 

Computer/internet is running much faster and the multiple dll *32 files in task manager are no longer present.  A few issues I still appear to be having:

 

1. I am getting no sound when I run any videos on line (youtube,etc), but sound works fine if I jut play a music file from computer. Not sure if related or if I just need to reload my sound drivers?

2. Malwarebytes program still does run.  Maybe I need to remove and reload?

3. No other issues that I am aware of at this time.

 

Thanks.

I do not see an Anti-virus program installed, is that correct?

 

Next,

 

Please run a Threat Scan with MBAM.  If you're unable to run or complete the scan as shown below please see the following:

MBAM Clean Removal Process 2x

Follow the relevant steps and ensure to run mbam-clean tool after UNinstalling Malwarebytes.

 

When reinstalling the program please try the latest version from here:

http://www.malwarebytes.org/mwb-download/

Right click and choose "Run as administrator" to open Malwarebytes Anti-Malware and from the Dashboard please Check for Updates by clicking the Update Now... link

Open up Malwarebytes > Settings > Detection and Protection > Enable Scan for rootkit and Under Non Malware Protection set both PUP and PUM to Treat detections as malware.

Click on the SCAN button and run a Threat Scan with Malwarebytes Anti-Malware by clicking the Scan Now>> button.

Once completed please click on the History > Application Logs and find your scan log and open it and then click on the "copy to clipboard" button and post back the results on your next reply.

I do not think so - for the antivirus and MBAM, do I go ahead and delete/quarantine files as directed going forward?  I have not done anything without your feedback up to this point, so just want to be sure.  If you say it looks ok from latest files, think we are good to go as I am not noticing anything outside the norm.

 

many thanks for your help and for supporting such a great forum that users can come and ask for sound advice.

Yes the logs look good, I just need confirmation as to how your system responds. If all ok we can cleaan up:

 

Download and run this:

http://download.bleepingcomputer.com/sUBs/CF_UNINST.EXE

That will remove Combofix and associated folders...
 

Next,

 

Download "Delfix by Xplode" and save it to your desktop.

 

Or use the following if first link is down:

 

"Delfix link mirror"

 

Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator

 

Make Sure the following items are checked:

 


    Activate UAC
    Remove disinfection tools
    Create registry backup
    Purge System Restore
    Reset system settings

 

Now click on "Run" and wait patiently until the tool has completed.

 

The tool will create a log when it has completed. We don't need you to post this.

 

Part of the routine will be to create a registry back up with ERUNT,  the back up will be created here:

 

C:\Windows\ERUNT

 

When all is known to be well with your system you can delete that back up folder if you consider it as not needed...

 

Any remnant files/logs from tools we have used can be deleted…

 

Next,

 

Read the following link to fully understand PC security and best practices, you may find it useful....

 

http://www.bleepingcomputer.com/forums/t/407147/answers-to-common-security-questions-best-practices/#entry2316629

 

Let me know if we are ok to close out..

 

Thank you,

 

Kevin
