Computer infected with malware

Viruses and worms
1

Hi,
My system has been behaving weirdly in the last few days and seems to have been infected with malware. Whenever I open a webpage in my browser(firefox),
it is being redirected to a different page in the first attempt. When I try opening the page the second time, it mostly goes to the right page. The system crashes and reboots while
running flash videos from time to time. Also, when I open a thumbnail image in the internet, it opens a different image. I hear pings in my system as if some process is executing in the background. When I checked taskmgr, I found some unfamiliar exes running. I tried to kill them, but they kept reappearing.

As advised in your forum, I ran MalwareBytes Anti-Malware, OTL and aswMBR.

MalwareBytes helped clean up some errors(I have attached the logs of it that came up when I ran it the first time).

I am unable to run OTL. The system crashes with a blue screen every time I try to run it. So I skipped running it.

I ran aswMBR and saved the logs. I have attached it here.

Can you please look in the logs and suggest ways to clean up the malware in my system? It would be great if you could.

Looking forward to hearing from you.

Thanks,
Swetha

Hi,

Are you able to run OTL in Safe Mode? If so do that and then attach the logs. :slight_smile:

Hi jeffc,
I ran OTL in safe mode and I have attached logs of the same. Please look in to it and let me know.

Thanks

I need to ask…is this a business/corporate computer?

5

This was a laptop that I purchased from my previous employer when I moved out of my company. It is my personal laptop now and is not a business/corporate laptop.

Ok…great!

I am at work right now but will return shortly. :slight_smile:

Sure. Thanks. :slight_smile:

Hi,

Please download and run ERUNT (Emergency Recovery Utility NT). This program allows you to keep a complete backup of your registry and restore it when needed. The standard registry backup options that come with Windows back up most of the registry but not all of it. ERUNT however creates a complete backup set, including the Security hive and user related sections. ERUNT is easy to use and since it creates a full backup, there are no options or choices other than to select the location of the backup files. The backup set includes a small executable that will launch the registry restore if needed. **Remember if you are using Windows Vista as your operating system right-click the executable and Run as Administrator.

Run OTL.exe

[*]Copy/paste the following text written inside of the code box into the Custom Scans/Fixes box located at the bottom of OTL

Hi jeffce,
Thanks for the prompt response. I ran ERUNT and OTL as you advised. I have attached the logs of OTL after running fix and doing a scan after reboot.

Hi jeffce,
I ran OTL and have attached the logs of the two runs. Thanks.

Hi,

How is your system running now? :slight_smile:

15

Hi jeffce,
Thanks for those steps. The system seems better, however, webpages are still getting re-directed and videos are freezing from time to time. :frowning:

Hi,

Ok lets dig further… :slight_smile:

* IMPORTANT !!! Save ComboFix.exe to your Desktop

[*]Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools.

[*]Double click on ComboFix.exe & follow the prompts.

[*]As part of it’s process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. With malware infections being as they are today, it’s strongly recommended to have this pre-installed on your machine before doing any malware removal. It will allow you to boot up into a special recovery/repair mode that will allow us to more easily help you should your computer have a problem after an attempted removal of malware.

Once the Microsoft Windows Recovery Console is installed using ComboFix, you should see the following message:

http://img.photobucket.com/albums/v706/ried7/RC2-1.png

Click on Yes, to continue scanning for malware.

When finished, it shall produce a log for you. Please include the C:\ComboFix.txt in your next reply.

Notes:

1.Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
2. ComboFix may reset a number of Internet Explorer’s settings, including making I-E the default browser.
3. CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run. If CF runs into difficulty and terminates prematurely, the connection can be manually restored by restarting your machine.

In your next reply please attach the logs made by TKSSKiller and ComboFix. :slight_smile:

Thanks jeffce. I ran the two software as per the instructions and attached the logs for you to look at.

Hi,

Looks like we found a nasty one…

Re-run TDSSKiller and this time remove the following entries and attach the new log.

\Device\Harddisk0\DR0 ( TDSS File System ) - skipped by user \Device\Harddisk0\DR0 ( TDSS File System ) - User select action: Skip
19

I removed that entry jeffce. Here is the log generated.

Good job! That was a nasty one.
