Hello, MAD_22 and again
Welcome to the Bleeping Computer Forums. My name is Thomas (Tom is fine), and I will be helping you fixing your problems.

If you do not make a reply in 5 days, we will have to close your topic.

You may want to keep the link to this topic in your favourites. Alternatively, you can click the Posted Image button at the top bar of this topic and Track this Topic. The topics you are tracking can be found here.

Please take note of some guidelines for this fix:
  • Refrain from making any changes to your computer including installing/uninstall programs, deleting files, modifying the registry, and running scanners or tools. Doing so could cause changes to the directions I have to give you and prolong the time required. Further more, you should not be taking any advice relating to this computer from any other source throughout the course of this fix.
  • If you do not understand any step(s) provided, please do not hesitate to ask before continuing. I would much rather clarify instructions or explain them differently than have something important broken.
  • Even if things appear to be better, it might not mean we are finished. Please continue to follow my instructions and reply back until I give you the "all clean". We do not want to clean you part-way, only to have the system re-infect itself.
  • Please reply using the Posted Image button in the lower right hand corner of your screen. Do not start a new topic. The logs that you post should be pasted directly into the reply. Only attach them if requested or if they do not fit into the post.
  • Old topics are closed after 3 days with no reply, and working topics are closed after 5 days. If for any reason you cannot complete instructions within that time, that's fine, just post back here so that we know you're still here.
  • Please set your system to show all files.
    Click Start, open My Computer, select the Tools menu and click Folder Options.
    Select the View Tab. Under the Hidden files and folders heading, select Show hidden files and folders.
    Uncheck: Hide file extensions for known file types
    Uncheck the Hide protected operating system files (recommended) option.
    Click Yes to confirm.





Step 1

Your log(s) show that you are using so called peer-to-peer or file-sharing programmes (in your case BitComet). These programmes allow to share files between users as the name(s) suggest. In today's world the cyber crime has come to an enormous dimension and any means is used to infect personal computers to make use of their stored data or machine power for further propagation of the malware files. A popular means is the use of file-sharing tools as a tremendous amount of prospective victims can be reached through it.

It is therefore possible to be infected by downloading manipulated files via peer-to-peer tools and thus suggested to be used with intense care. Some further readings on this subject, along the included links, are as follows: "File-Sharing, otherwise known as Peer To Peer" and "Risks of File-Sharing Technology."

It is also important to note that sharing entertainment files and proprietary software infringes the copyright laws in many countries over the world and you are putting yourself at risk of being indicted through organisations watching over the rights of the authors of such files (i.e. the RIAA for music files, or the MPAA for movie files in the USA) or the authors of the files themselves.

Naturally there are also legal ways to use these services, such as downloading Linux distributions or office suites such as "Open Office."





Step 2

Your Java is out of date. Older versions have vulnerabilities that malicious sites can use to exploit and infect your system. Please follow these steps to remove older version Java components and update:
  • Download the latest version of Java Runtime Environment (JRE) Version 6 and save it to your desktop.
  • Scroll down to where it says "Java Runtime Environment (JRE) 6 Update 16...allows end-users to run Java applications".
  • Click the "Download" button to the right.
  • Select your Platform: "Windows".
  • Select your Language: "Multi-language".
  • Read the License Agreement, and then check the box that says: "Accept License Agreement".
  • Click Continue and the page will refresh.
  • Click on the link to download Windows Offline Installation and save the file to your desktop.
  • Close any programs you may have running - especially your web browser.
  • Go to Start > Settings > Control Panel, double-click on Add/Remove Programs and remove all older versions of Java.
  • Check (highlight) any item with Java Runtime Environment (JRE or J2SE) in the name.
  • Click the Remove or Change/Remove button.
  • Repeat as many times as necessary to remove each Java versions.
  • Reboot your computer once all Java components are removed.
  • Then from your desktop double-click on jre-6u16-windows-i586-p.exe to install the newest version.





Step 3

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM 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.
  • 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 Quick 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.






Step 4
  • Download random's system information tool (RSIT) by random/random from here and save it to your desktop.
  • Double click on RSIT.exe to run RSIT.
  • Click Continue at the disclaimer screen.
  • Once it has finished, two logs will open. Please post only the content of log.txt





Please post back with:
  • Malwarebytes-Logfile
  • RSIT log.txt

Hi,

System drive C: has 6 GB (11%) free of 57 GB
Total RAM: 503 MB (12% free)


That is your main problem I Think. You have not enough RAM and not enough disk space to do anything that can speed up your system. Please do the following:


Step 1

Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.





Step 2

Backup Your Registry with ERUNT
  • Please use the following link and scroll down to ERUNT and download it.
    http://aumha.org/freeware/freeware.php
  • For version with the Installer:
    Use the setup program to install ERUNT on your computer
  • For the zipped version:
    Unzip all the files into a folder of your choice.
Click Erunt.exe to backup your registry to the folder of your choice.

Note: to restore your registry, go to the folder and start ERDNT.exe





Step 3

We need to run an OTM script
  • Please download OTM by OldTimer and save it to your desktop.
  • Double click the OTM icon on your desktop.
  • Paste the following code under the Paste Instructions for Items to be Moved area. Do not include the word "Code".
    :Reg
    [-HKEY_CURRENT_USER\software\microsoft\windows\currentversion\explorer\mountpoints2\{291dfae5-186f-11dd-a6f8-001641088a63}]
    [-HKEY_CURRENT_USER\software\microsoft\windows\currentversion\explorer\mountpoints2\{3cc12af8-8a88-11dc-a6ca-001641088a63}]
    [-HKEY_CURRENT_USER\software\microsoft\windows\currentversion\explorer\mountpoints2\{add338cf-2a7d-11dd-a6fa-001641088a63}]
    [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run]
    ""=-
    
    :Commands
    [EmptyTemp]
  • Push the large MoveIt! button.
    **OTM may ask to reboot the machine. Please do so if asked.
  • Copy/Paste the contents under the Results line here in your next reply.
  • If you are unable to copy/paste from this window (as will be the case if the machine was rebooted), open Notepad (Start->All Programs->Accessories->Notepad), click File->Open, in the File Name box enter *.log and press the Enter key, navigate to the C:\_OTM\MovedFiles folder, and open the newest .log file present, and copy/paste the contents of that document back here in your next post.




Step 4

Click "start" on the taskbar and then click on the "Control Panel" icon.
Please doubleclick the "Add or Remove Programs" icon
A list of programs installed will be "populated" this may take a bit of time.
Please uninstall everything what isn't really necessary.

Additional instructions can be found here if needed.






Step 5

Please run a BitDefender Online Scan
  • Click I Agree to agree to the EULA.
  • Allow the ActiveX control to install when prompted.
  • Click Click here to scan to begin the scan.
  • Please refrain from using the computer until the scan is finished. This might take a while to run, but it is important that nothing else is running while you scan.
  • When the scan is finished, click on Click here to export the scan results.
  • Save the report to your desktop so you can post it in your next reply.





Please post back with:
  • OTM-Logfile
  • Bitdefender-Logfile
  • Fresh RSIT-Logfile
  • How is your system running?

schrauber

Hi :thumbup2:


Step 1

Run Hijackthis, choose do a system scan only and place a check next to the following:

R3 - URLSearchHook: &Yahoo! Toolbar - {EF99BD32-C1FB-11D2-892F-0090271D4F88} - (no file)

Close all open windows and click on fix checked.





Step 2

Please run OTM again and click on the Cleanup-Button. This will remove OTM and all helper tools we have used. If OTM will reboot the system, please allow it.






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 :)

Hiding Hidden Files
Please set your system to hide all hidden files.
Click Start, open My Computer, select the Tools menu and click Folder Options.
Select the View Tab. Under the Hidden files and folders heading, uncheck Show hidden files and folders.
Check: Hide file extensions for known file types
Check the Hide protected operating system files (recommended) option.
Click Yes to confirm.

Purging System Restore Points
Now you should Set a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since System Restore is a protected directory, your tools can not access it to delete these bad files which sometimes can reinfect your system. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then go to Start > Run and type: Cleanmgr
  • Click "OK".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.
One of the most common questions found when cleaning Spyware or other Malware is "how did my machine get infected?". There are a variety of reasons, but the most common ones are that you are going to sites that you are not practicing Safe Internet, you are not running the proper security software, and that your computer's security settings are set too low.

Below I have outlined a series of categories that outline how you can increase the security of your computer so that you will not be infected again in the future.


Practice Safe Internet

One of the main reasons people get infected in the first place is that they are not practicing Safe Internet. You practice Safe Internet when you educate yourself on how to properly use the Internet through the use of security tools and good practice. Knowing how you can get infected and what types of files and sites to avoid will be the most crucial step in keeping your computer malware free. The reality is that the majority of people who are infected with malware are ones who click on things they shouldn't be clicking on. Whether these things are files or sites it doesn't really matter. If something is out to get you, and you click on it, it most likely will. Below are a list of simple precautions to take to keep your computer clean and running securely:
  • If you receive an attachment from someone you do not know, DO NOT OPEN IT! Simple as that. Opening attachments from people you do not know is a very common method for viruses or worms to infect your computer.

  • If you receive an attachment and it ends with a .exe, .com, .bat, or .pif do not open the attachment unless you know for a fact that it is clean. For the casual computer user, you will almost never receive a valid attachment of this type.

  • If you receive an attachment from someone you know, and it looks suspicious, then it probably is. The email could be from someone you know infected with a malware that is trying to infect everyone in their address book.

  • If you are browsing the Internet and a popup appears saying that you are infected, ignore it!. These are, as far as I am concerned, scams that are being used to scare you into purchasing a piece of software. For an example of these types of popups, or Foistware, you should read this article: Foistware, And how to avoid it.

    There are also programs that disguise themselves as Anti-Spyware or security products but are instead scams. For a list of these types of programs we recommend you visit this link: Rogue/Suspect Anti-Spyware Products & Web Sites

  • Another tactic to fool you on the web is when a site displays a popup that looks like a normal Windows message or alert. When you click on them, though, they instead bring you to another site that is trying to push a product on you. We suggest that you close these windows by clicking on the X instead of the OK button. Alternatively, you can check to see if it's a real alert by right-clicking on the window. If there is a menu that comes up saying Add to Favorites... you know it's a fake.

  • Do not go to adult sites. I know this may bother some of you, but the fact is that a large amount of malware is pushed through these types of sites. I am not saying all adult sites do this, but a lot do.

  • When using an Instant Messaging program be cautious about clicking on links people send to you. It is not uncommon for infections to send a message to everyone in the infected person's contact list that contains a link to an infection. Instead when you receive a message that contains a link, message back to the person asking if it is legit before you click on it.

  • Stay away from Warez and Crack sites! In addition to the obvious copyright issues, the downloads from these sites are typically overrun with infections.

  • Be careful of what you download off of web sites and Peer-2-Peer networks. Some sites disguise malware as legitimate software to trick you into installing them and Peer-2-Peer networks are crawling with it. If you want to download a piece of software a from a site, and are not sure if they are legitimate, you can use McAfee Siteadvisor to look up info on the site.

  • DO NOT INSTALL any software without first reading the End User License Agreement, otherwise known as the EULA. A tactic that some developers use is to offer their software for free, but have spyware and other programs you do not want bundled with it. This is where they make their money. By reading the agreement there is a good chance you can spot this and not install the software.
Visit Microsoft's Windows Update Site Frequently

It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.


Make Internet Explorer 7 more secure
  • From within Internet Explorer click on the Tools menu and then click on Options.
  • Click once on the Security tab
  • Click once on the Internet icon so it becomes highlighted.
  • Click once on the Custom Level button.
    • Change the Download signed ActiveX controls to Prompt
    • Change the Download unsigned ActiveX controls to Disable
    • Change the Initialize and script ActiveX controls not marked as safe to Disable
    • Change the Installation of desktop items to Prompt
    • Change the Launching programs and files in an IFRAME to Prompt
    • Change the Navigate sub-frames across different domains to Prompt
    • When all these settings have been made, click on the OK button.
    • If it prompts you as to whether or not you want to save the settings, press the Yes button.
  • Next press the Apply button and then the OK to exit the Internet Properties page.
Update your AntiVirus Software

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

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.



Follow this list and your potential for being infected again will reduce dramatically.

schrauber
