i believe im infected


Recommended Posts

i tried to use the hijack program to check/clean unwanted stuff on my computer and i got a message saying,

 

"for some reason your system denied write access to the Hosts File. If any hijacked domains are in this file, Hijack This may NOT be able to fix this. 

If that happens, you need to edit the file yourself. To do this, Click Start, Run and type:

 

notepad C:\Windows\System32\drivers\etc\hosts

 

and press enter. Find the line(s) Hijack This reports and delete them. Save the file as 'host.' (with quotes), and reboot."

 

i followed that but there was no Hijack files there.

 

i just found out from somebody here that Hijack is obsolete, but im thinking im infected somehow or by someone. 

 

any help to figure out and if so clean my system of such threats would be greatly appreciated.

 

attached are the dds logs that were requested

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 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 run a Quick Scan with Malwarebytes
Open up Malwarebytes > Settings Tab > Scanner Settings > Under action for PUP > Select: Show in Results List and Check for removal.
Please Update and run a Quick Scan with Malwarebytes Anti-Malware, post back the report.
Make sure that everything is checked, and click Remove Selected if anything is found.
 
 
STEP 03

  • 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!!

At this time there are no more signs of an infection on your system.
However if you are still seeing any signs of an infection please let me know.

Let's go ahead and remove the tools and logs we've used during this process.Please read the posted information as it will give you methods to help prevent future infections.

Most of the tools used are potentially dangerous to use unsupervised or if ran at the wrong time.
They are often updated daily so if you went to use them again in the future they would be outdated anyways.

The following procedures will implement some cleanup procedures to remove these tools.
It will also reset your System Restore by flushing out previous restore points and create a new restore point.
It will also remove all the backups our tools may have created.

Uninstall ComboFix (if used):

  • Turn off all active protection software including your antivirus.
  • Push the "Windows key" + "R" (between the "Ctrl" button and "Alt" Button)
  • Please copy and past the following into the box ComboFix /Uninstall and click OK.
  • Note the space between the X and the /Uninstall, it needs to be there.

CF-Uninstall.png

 
Remove the rest of the tools used:
 
Please download
OTCleanIt
and save it to your Desktop. This tool will remove all the tools we used to clean your pc.

  • Double-click OTCleanIt.exe.
  • Click the CleanUp! button.
  • Select Yes when the "Begin cleanup Process?" prompt appears.
  • If you are prompted to Reboot during the cleanup, select Yes.
  • The tool will delete itself once it finishes, if not go ahead and delete it by yourself.
  • If asked to restart the computer, please do so

OTCleanIt
attempting to contact the internet, please allow it to do so.

As Java seems to get exploited on a regular basis I advise not using Java if possible but to at least disable java in your web browsers
How do I disable Java in my web browser? - Disable Java

A lot of reading here but if you take the time to read a bit of it you'll see why/how infections and general damage are so easily inflicted on the computer. There is also advice on how to prevent it and keep the system working well. Don't forget about good, solid backups of your data to an external drive that is not connected except when backing up your data. If you leave a backup drive connected and you do get infected it can easily damage, encrypt, delete, or corrupt your backups as well and then you'd lose all data.
Nothing is 100% bulletproof but with a little bit of education you can certainly swing things in your favor.


If you're not currently using Malwarebytes PRO then you may want to consider purchasing the product which can also help greatly reduce the risk of a future infection.

Please download the following scanner from Kaspersky and save it to your computer: TDSSkiller

The startup you describe sounds normal to me.
 
Please uninstall ALL versions of Java from the Control Panel, Add/Remove.
Then run the following

Please download JavaRa-1.16 and save it to your computer.

  • Double click to open the zip file and then select all and choose Copy.
  • Create a new folder on your Desktop named RemoveJava and paste the files into this new folder.
  • Quit all browsers and other running applications.
  • Right-click on JavaRa.exe in RemoveJava folder and choose Run as administrator to start the program.
  • From the drop-down menu, choose English and click on Select.
  • JavaRa will open; click on Remove Older Versions to remove the older versions of Java installed on your computer.
  • Click Yes when prompted. When JavaRa is done, a notice will appear that a logfile has been produced. Click OK.
  • A logfile will pop up. Please save it to a convenient location and post it in your next reply.

Then you should have the MBAR Anti-Rootkit installer there on your system.  Go inside the folder and you'll find a folder called PLUGIN and in there a file named FIXDAMAGE.EXE please right click over that file and choose 'Run as administrator" and then restart the computer.
 
Next, Please download aswMBR ( 4.5MB ) to your desktop.

  • Double click the aswMBR.exe icon, and click Run.
  • There will be a short delay before the next dialog box comes up. Please just wait a minute or two.
  • When asked if you'd like to "download the latest Avast! virus definitions", click Yes.
  • Typically this is about a 100MB download so depending on your connection speed it can take a short while to download and become ready.
  • Click the Scan button to start the scan once the update has finished downloading
  • On completion of the scan, click the save log button, save it to your desktop, then copy and paste it in your next reply.

Note: There will also be a file on your desktop named MBR.dat do not delete this for now. It is an actual backup of the MBR (master boot record).
