Hi,

What software do you use to see if you are infected by RAT.

My computer is running extremely slow at the moment and I believe I got infected by a RAT.

Can anyone assist?

Thank you in advance.

Hello and welcome to Bleeping Computer!

I am HelpBot: an automated program designed to help the Bleeping Computer Staff better assist you! This message contains very important information, so please read through all of it before doing anything.

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

To help Bleeping Computer better assist you please perform the following steps:

***************************************************

Posted Image In order to continue receiving help at BleepingComputer.com, YOU MUST tell me if you still need help or if your issue has already been resolved on your own or through another resource! To tell me this, please click on the following link and follow the instructions there.

CLICK THIS LINK >>> http://www.bleepingcomputer.com/logreply/459977 <<< CLICK THIS LINK



If you no longer need help, then all you needed to do was the previous instructions of telling me so. You can skip the rest of this post. If you do need help please continue with Step 2 below.

***************************************************

Posted Image If you still need help, I would like you to post a Reply to this topic (click the "Add Reply" button in the lower right hand of this page). In that reply, please include the following information:

  • If you have not done so already, include a clear description of the problems you're having, along with any steps you may have performed so far.
  • A new DDS and GMER log. For your convenience, you will find the instructions for generating these logs repeated at the bottom of this post.
    • Please do this even if you have previously posted logs for us.
    • If you were unable to produce the logs originally please try once more.
    • If you are unable to create a log please provide detailed information about your installed Windows Operating System including the Version, Edition and if it is a 32bit or a 64bit system.
    • If you are unsure about any of these characteristics just post what you can and we will guide you.
  • Please tell us if you have your original Windows CD/DVD available.
  • Upon completing the above steps and posting a reply, another staff member will review your topic and do their best to resolve your issues.

Thank you for your patience, and again sorry for the delay.

***************************************************

We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE


We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows, you should not bother creating a GMER log.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice


Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log


As I am just a silly little program running on the BleepingComputer.com servers, please do not send me private messages as I do not know how to read and reply to them! Thanks!

Please run MBAM and SAS first of all. RATs exist but they are not very common so we may find nothing

Please download Posted Image Malwarebytes Anti-Malware and save it to your desktop.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application or, if you are using Vista, right-click and select Run As Administrator on mbam-setup.exe to install the application.
  • 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 MBAM won't update then download and update MBAM on a clean computer then save the rules.ref folder to a memory stick. This file is found here: 'C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware' then transfer it across to the infected computer.
  • 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 and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.


And

Download Superantispyware
  • Load Superantispyware and click the check for updates button.
  • Once the update is finished click the scan your computer button.
  • Check Perform Complete Scan and then next.
  • Superantispyware will now scan your computer and when its finished it will list all the infections it has found.
  • Make sure that they all have a check next to them and press next.
  • Click finish and you will be taken back to the main interface.
  • Click Preferences and then click the statistics/logs tab. Click the dated log and press view log and a text file will appear.
  • Copy and paste the log onto the forum.

Some trojan activity in your recycle bin, not sure why they are there but if your antivirus has been bleating it's probably picking up the files here.

Please run an online scan with ESET - This can take some time but is very thorough

I'd like us to scan your machine with ESET OnlineScan
  • Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  • Click the Posted Image button.
  • For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
    • Click on Posted Image to download the ESET Smart Installer. Save it to your desktop.
    • Double click on the Posted Image icon on your desktop.
  • Check Posted Image
  • Click the Posted Image button.
  • Accept any security warnings from your browser.
  • Under scan settings, check Posted Image and check 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.
  • Copy and paste the resulting log in your next reply
If no log is generated that means nothing was found. Please let me know if this happens.

If you think a log should have been generated then go to C:\Program Files\ESET\ESET Online Scanner\log.txt to find it.

Trojans love to surf in on keygens.

Someone on this system was trying to access cracks or a 'keygen'....this is a certain way to attract malware to your system. As well as being illegal, 'Cracks' and 'Keygens' are often associated or loaded with malware, and should be avoided (along with 'crack' sites).

The machine looks better, how's it running?

You're welcome, Dongta69

A quick clean up and you're done.

You're clean. Good stuff! :thumbup2:

Let's do some clearing up

If you used DeFogger now is the time to enable your CD emulation software again.


We Need to Clean Up our Mess
Download and Run OTC

We will now remove the tools we used during this fix using OTC.

  • Download OTC by OldTimer and save it to your desktop.
  • Double click Posted Image icon to start the program. If you are using Vista, please right-click and choose run as administrator
  • Then Click the big Posted Image button.
  • You will get a prompt saying "Begin Cleanup Process". Please select Yes.
  • Restart your computer when prompted.
If you still have any tools or logs leftover on your computer you can go ahead and delete those off of your computer now.

Now create a new system protection point

1. Open System by clicking the Start button, right-clicking Computer, and then clicking Properties.

2. In the left pane, click System protection. If you're prompted for an administrator password or confirmation, type the
password or provide confirmation.

3. Click the System Protection tab, and then click Create.

4. In the System Protection dialog box, type a description, and then click Create.
------------------------------------------------------------------------------------------------------------------------

Here's some advice on how you can keep your PC clean


Use and update your AntiVirus Software

You must have a good antivirus. There are plenty to choose from but I personally recommend the free options of Avast and Avira Antivir - though if you choose Avira you should make sure that you uncheck the box offering to install the Ask toolbar. If you want to purchase a security program then I recommend any of the following: AVG, Norton, McAfee, Kaspersky and ESET Nod32.

It is imperative that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out. If you use a commercial antivirus program you must make sure you keep renewing your subscription. Otherwise, once your subscription runs out, you may not be able to update the programs virus definitions.


Make sure your applications have all of their updates

Use this next program to check for updates for programs already on your system. Download Security Check by screen317 from here
  • Save it to your Desktop.
  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
  • A Notepad document should open automatically, make sure that updates on any that are flagged are carried out as soon as possible

It is also possible for other programs on your computer to have security vulnerability that can allow malware to infect you. Therefore, it is also a good idea to check for the latest versions of commonly installed applications that are regularly patched to fix vulnerabilities. You can check these by visiting Secunia Software Inspector and Calendar of Updates.


Install an AntiSpyware Program

A highly recommended AntiSpyware program is SuperAntiSpyware. You can download the free Home Version. or the Pro version for a 15 day trial period.

Installing this or another recommended program will provide spyware & hijacker protection on your computer alongside your virus protection. You should scan your computer with an AntiSpyware program on a regular basis just as you would an antivirus software.


Finally, here's a treasure trove of antivirus, antimalware and antispyware resources


That's it, happy surfing!

Cheers.

Hey,

Thank you for helping me out.

Is there anyway you can teach me more about how to manually detect viruses/trojans and getting rid of them?
