Hi, I require assistance in fixing a problem with malware on my computer.

I was working on my computer and everything was fine and dandy, when I made the foolish mistake of downloading malicious files onto my computer. Things got messed up, and two things started happening to my computer:

1) Whenever I tried running a program on my computer, it would then ask me which program I want to use to open the program! For example, if I tried opening firefox.exe, it would ask which program I would use to open it. It was a bit redundant, but I was able to open some, but not all programs this way.

2) My internet doesn't work anymore, due to apparently reconfigured proxy settings (undoubtedly due to the malware). When I tried opening up Firefox, it gives me a message saying, "The proxy server is refusing connections. Firefox is configured to use a proxy server that is refusing connections." It sometimes worked in Safe Mode, but now it doesn't even work there.

After running Ad-Aware and Super Anti Spyware multiple times, I was able to fix the first problem - at least, it hasn't re-emerged. However, the second issue remains, and I suspect that the malware I picked up re-configured something on my computer. When I first started scanning for the malware, two, high-priority threats were picked up, which were counted as registry items. Ad-Aware didn't seem capable of getting rid of them, although SAS was.

What should I do? I'm currently in Safe Mode running SAS and more malicious files are being found, but if that doesn't fix the problem, I'm in a mess. Any help would be greatly appreciated.

Hi cryptodan,

I think you're asking for logs created by DDS, which I am unable to do, since my internet - or rather, my browser - doesn't work, and I haven't already downloaded the program (I'm using a laptop with no means of transferring files between it and the computer with problems). If this isn't what you're referring to, or if there is another way to provide logs, please tell me how.

Update: The two browsers that I have (Firefox and Internet Explorer) are unable to access the internet due to the "proxy" problem, so I can't use browsers on my computer However, I can still access the internet in other ways, such as updating AVG and playing online games. Even pinging websites using the cmd command seems to run smoothly. I've removed all the files detected by SAS, but the proxy problem persists.

Ahh OK, sorry for misunderstanding. I scanned the computer multiple times. The last one is when I let the scan finish fully. Here are the logs, in order:

(The format might be a bit off, since I'm typing out the exact logs onto my laptop from the desktop screen, but the overall details should still be here.)

Hello,

And welcome to BleepingComputer.com, before we can assist you with your question of: Am I infected? You will need to perform the following tasks and post the logs of each if you can.

Malwarebytes Anti-Malware

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Full Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.


Now GMER

GMER does not work in 64bit Mode!!!!!!

Please download GMER from one of the following locations and save it to your desktop:

  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic Full Scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning
.

Sorry for the late-ish reply, I've had a long day. Anyway, I did as you asked, and the problem persists. When using Malwarebites, I was prompted to restart my computer, and did NOT reboot into safe mode. I'm not sure if that's what you asked of me or not.

Here are the logs of both processes.

Hello,

Now for the hard and frustrating part: waiting.

Now that you have posted a log, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :cherry:
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.
