I bought a new laptop a few days ago and have been installing software the last couple of days. I think that my computer may have come infected at some point as I started to get some real problems - programs losing settings, some programs stopping working such as chrome. Then I couldn't start windows and tried to recover to a recovery point but that got stuck and didn't complete either. I tried various things (sfc /scannow, restoring from original media etc) and seemingly windows is now working ok.

However I am suspicious that something untoward still lurks.

Please could someone take a look at the attached dds logs? No gmer logs as I'm running win7 x64.

Thanks in advance for any help,

John

Hello and :welcome: to BleepingComputer!

COMBOFIX
---------------
Please download ComboFix from one of these locations:
Bleepingcomputer
ForoSpyware
  • Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. (Click on this link to see a list of programs that should be disabled. The list is not all inclusive.)
  • Double click on Combofix.exe and 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.
  • Follow the prompts to allow ComboFix to download and install the Microsoft Windows Recovery Console, and when prompted, agree to the End-User License Agreement to install the Microsoft Windows Recovery Console.
**Please note: If the Microsoft Windows Recovery Console is already installed, or if you are running Vista, ComboFix will continue it's malware removal procedures.

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

Posted Image


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.
Please download Farbar Service Scanner and run it on the computer with the issue.
  • Make sure the following options are checked:
    • Internet Services
    • Windows Firewall
    • System Restore
    • Security Center
    • Windows Update
  • 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.

regards, Elise

Have attached those 2 files. Comnbofix hung at the 'preparing report' stage but a report was still produced.

Between when I first posted and now I have additionally performed a windows repair install.

Thanks for the help,

John

I see no malware here. Can you describe exactly what problem you still experience at this point?

regards, Elise

I'm not experiencing any problems right now - computer seems to be running fine. I was just concerned that there may be something untoward lurking and I wanted to make sure that I had totally eradiacted it as my computer was in a bad way. Loads of programs stopped working (itunes, lightroom to name 2), Windows wouldn't start, system restore failed, repair install failed first time, I had a notification for unauthorised access attempt to my google account.

So if you say my computer appears clean I am inclined to agree! Many thanks for taking a look at the logs and helping me out. Appreciated.

John

In that case be sure to change you Google password, just in case...

P2P WARNING
-------------------
Going over your logs I noticed that you have uTorrent installed.
  • Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs.
  • They are a security risk which can make your computer susceptible to a wide variety of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites.
  • Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users.
  • The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications.
It is pretty much certain that if you continue to use P2P programs, you will get infected again.
I would recommend that you uninstall uTorrent, however that choice is up to you. If you choose to remove these programs, you can do so via Start > Control Panel > Add/Remove Programs.

If you wish to keep it, please do not use it until your computer is cleaned.


ESET ONLINE SCANNER
----------------------------
I'd like us to scan your machine with ESET OnlineScan
  • Hold down Control and click on this link to open ESET OnlineScan in a new window.
  • Click the Posted Image button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on esetsmartinstaller_enu.exe to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Posted Image
      icon on your desktop.
  • Check "YES, I accept the Terms of Use."
  • Click the Start button.
  • Accept any security warnings from your browser.
  • Under scan settings, check "Scan Archives" and "Remove found threats"
  • Click Advanced settings and select the following:
    • Scan potentially unwanted applications
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth technology
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, click List Threats
  • Click Export, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Click the Back button.
  • Click the Finish button.

regards, Elise

Yes, the very first thing that I did was to change my google, facebook and other passwords! I have 2-factor for google & facebook so am a little safer than your average user.

I ran ESET, here's the results:


D:\Users\John\Downloads\cdbxp_setup_4.4.0.2905.exe Win32/OpenCandy application deleted - quarantined
D:\Users\John\Downloads\KeyFinderInstaller.exe Win32/OpenCandy application deleted - quarantined

The cdbxp is CD Burner XP - CD/DVD burning software that I use. No idea what 'KeyFinderInstaller.exe' is, I definitely did not download that intentionally.

Thanks, John

Actually I do know what what 'KeyFinderInstaller.exe' is. It's the program that I used to find the serial number for my copy of Win 7 Home Premium that came installed on my laptop so that I could perform the repair install.

Good to hear you know both files. :)

ALL CLEAN
--------------
Your machine appears to be clean, please take the time to read below on how to secure the machine and take the necessary steps to keep it clean :)

Please do the following to remove the remaining programs from your PC:
  • Delete the tools used during the disinfection:
  • Click start > run and type combofix /uninstall, press enter. This will remove Combofix from your computer.
Please read these advices, in order to prevent reinfecting your PC:
  • Install and update the following programs regularly:
    • an outbound firewall. If you are connected to the internet through a router, you are already behind a hardware firewall and as such you do not need an extra software firewall.
      A comprehensive tutorial and a list of possible firewalls can be found here.
    • an AntiVirus Software
      It is imperative that you update your AntiVirus Software on regular basis.If you do not update your AntiVirus Software then it will not be able to catch the latest threats.
    • an Anti-Spyware program
      Malware Byte's Anti Malware is an excellent Anti-Spyware scanner. It's scan times are usually under ten minutes, and has excellent detection and removal rates.
      SUPERAntiSpyware is another good scanner with high detection and removal rates.
      Both programs are free for non commercial home use but provide a resident and do not nag if you purchase the paid versions.
    • Spyware Blaster
      A tutorial for Spywareblaster can be found here. If you wish, the commercial version provides automatic updating.
  • Keep Windows (and your other Microsoft software) up to date!
    I cannot stress how important this is enough. Often holes are found in Internet Explorer or Windows itself that require patching. Sometimes these holes will allow an attacker unrestricted access to your computer.
    Therefore, please, visit the Microsoft Update Website and follow the on screen instructions to setup Microsoft Update. Also follow the instructions to update your system. Please REBOOT and repeat this process until there are no more updates to install!!
  • Keep your other software up to date as well
    Software does not need to be made by Microsoft to be insecure. You can use the Secunia Online Software occasionally to help you check for out of date software on yourmachine.
  • Stay up to date!
    The MOST IMPORTANT part of any security setup is keeping the software up to date. Malware writers release new variants every single day. If your software updates don't keep up, then the malware will always be one step ahead. Not a good thing.
Some more links you might find of interest:
Please reply to this topic if you have read the above information. If your computer is working fine, this topic will be closed afterwards.

regards, Elise

It appears that this issue is resolved, therefore I am closing the topic. If that is not the case and you need or wish to continue with this topic, please send me or any Moderator a Personal Message (PM) that you would like this topic re-opened.
