***Misspelled virus name on topic- it is: Java/Exdoer.FZ***
Hello, heard amazing things about this website so I thought I would come here for help. This is my moms laptop so I don't know how she got a virus. She only uses AOL and Messenger programs(Yahoo,Msn). She says she never downloads anything, but anyways:

Avira AntiVirus detected: Java/Exdoer.FZ

I am just concerned about her laptop now. I think it might be infected more, and hope it isn't compromised. Hopefully someone here can help me check it out further. I have installed Avira Anti Virus for AV- and she regularly updates and scans with MBAM and SAS.

Thanks!,
Mitchell

Thank you for the quick response Sparatcus. Before I proceed with your instructions, I am curious: Are you part of the malware removal team? Are you sure that is the correct steps to remove my infection? And I want to assure my computer is clean- are those instructions thorough and comply with what i'm asking?

Thanks!,
Mitchell

1. No, I am not part of the malware removal team.
2. I am as sure as can be that these programs will solve most issues.
(RKill terminates malicious programs, while SUPERAntiSpyware and MalwareBytes remove malware that most AntiVirus programs miss)

Hello M1tch,

I merged your new topic here. There is a preparation guide for posting in the log forum, but since you already have this topic here, let's be sure whether you actually need to go there.

Please download Malwarebytes Anti-Malware and save it to your desktop.Download Link 1
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.
    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 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.
In your reply, please provide an update of your computer status and the MBAM log.

Can you provide the full file path for the item Avira flagged? There should be a log where it reports what it finds. Please find it and copy and paste the entire line with the infected file. If you are unable to copy only that line, please copy and paste the entire log and post it as a reply to this topic.

That file is located in the Java cache which should be cleaned out on a regular basis.

To Clear the Java Runtime Environment (JRE) cache, do this:
  • Click Start > Settings > Control Panel.
  • Double-click the Java icon.
    -The Java Control Panel appears.
  • Click "Settings" under Temporary Internet Files.
    -The Temporary Files Settings dialog box appears.
  • Click "Delete Files".
    -The Delete Temporary Files dialog box appears.
    -There are three options on this window to clear the cache.
    • Delete Files
    • View Applications
    • View Applets
  • Click "OK" on Delete Temporary Files window.
    -Note: This deletes all the Downloaded Applications and Applets from the cache.
  • Click "OK" on Temporary Files Settings window.
  • Close the Java Control Panel.
You can also view these instructions along with screenshots here.

I also see that there is an old version of Java installed. This is a security risk as old versions of Java can be used to compromise the computer.

Important Note: Your version of 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 7 and save it to your desktop.
  • Look for "Java Platform, Standard Edition".
  • Click the "Download JRE" button to the right.
  • Read the License Agreement, and then check the box that says: "Accept License Agreement".
  • From the list, select your OS and Platform (32-bit or 64-bit).
  • If a download for an Offline Installation is available, it is recommended to choose that and save the file to your desktop.
  • Close any programs you may have running - especially your web browser.
Go to Posted Image > Control Panel, double-click on Add/Remove Programs or Programs and Features in Vista/Windows 7 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 and follow the onscreen instructions for the Java uninstaller.
  • 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-7-windows-i586.exe to install the newest version.
  • If using Windows 7 or Vista and the installer refuses to launch due to insufficient user permissions, then Run As Administrator.
  • When the Java Setup - Welcome window opens, click the Install > button.
  • If offered to install a Toolbar, just uncheck the box before continuing unless you want it.
  • The McAfee Security Scan Plus tool is installed by default unless you uncheck the McAfee installation box when updating Java.
Note: The Java Quick Starter (JQS.exe) adds a service to improve the initial startup time of Java applets and applications but it's not necessary.
To disable the JQS service if you don't want to use it:
  • Go to Start > Control Panel > Java > Advanced > Miscellaneous and uncheck the box for Java Quick Starter.
  • Click Ok and reboot your computer.

Generally speaking, Java does not need to be enabled to surf the web. For greater security, disable Java in the browser settings or through NoScript extension if using Firefox, and enable Java only for a site that needs it, disabling it again once you leave the site.

Lets see if there are other outdated programs that cause a security risk.

Download Security Check by screen317 from here or 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 called checkup.txt; please post the contents of that document in your next reply.

To Clear the Java Runtime Environment (JRE) cache, do this:

Click Start > Settings > Control Panel.

That's what I was thinking once I saw the full file path. Anyways, I can't find Java anywhere in Control Panel. I have looked everywhere for it.

Download the latest version of Java Runtime Environment (JRE) Version 7

done

called checkup.txt; please post the contents of that document in your next reply.

Hello,

I recall when I didn't have Java in the control panel either. There is another way of clearing Java cache.

Please download ATF Cleaner by Atribune & save it to your desktop. alternate download link
  • Close all open browsers before using, especially FireFox. <-Important!!!
  • Double-click ATF-Cleaner.exe to run the program.
  • Under Main "Select Files to Delete" choose: Select All.
  • Click the Empty Selected button.
  • If you use Firefox browser click Firefox at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • If you use Opera browser click Opera at the top and choose: Select All
  • Click the Empty Selected button.
    If you would like to keep your saved passwords, please click No at the prompt.
  • Click Exit on the Main menu to close the program.
Notes: On Vista, "Windows Temp" is disabled. To empty Temp, ATF-Cleaner must be Run As Administrator.
The Prefetch cleaning feature has been disabled for Vista Users. Tabs for applications that are not installed are grayed out.


+++++++++++++++++++

Question: Did you run Security Check before or after updating Java?

According to the scan, you still have old versions of Java installed. Those need to be uninstalled through the Add/Remove programs interface. Please see previous post for full instructions.

++++++++++++++++++++++++

According to the Security Check scan, you need to update the OS to the latest service pack. Running an OS on outdated service packs is a security risk that can be exploited.

So is mbam and security check sufficient enough to make sure there are no more infections?


Security Check doesn't check for infections, it checks for certain vulnerabilities on the computer.

Are there any symptoms or problems with the computer? Pop-ups, redirections, unexplained internet usage, others? If so, please describe.

Please download ATF Cleaner

Done

Done. I uninstalled everything with java ( adobe flash and java ) then re-installed them.

According to the Security Check scan, you need to update the OS to the latest service pack. Running an OS on outdated service packs is a security risk that can be exploited.

I am running Vista SP2. when I go to my Windows Updates it says I have the latest OS. I am concerned about this.

Are there any symptoms or problems with the computer?

No real problems. Just sluggish/slow.

I am going to post another log of securitycheck, make sure everything is how it should be:

edit: I notice security check still says my OS is out of date. Still says Java is out of date. I am very concerned.
