Hello, stu80.

OK, you appear clean of Alureon. Let's move on.





Step 1

Next, we need to update Java.
Your Java is out of date.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 21 and save it to your desktop.
  • Scroll down to where it says "JDK 6 Update 21 (JDK or JRE)...allows end-users to run Java applications".
  • Click the "Download JRE" 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) or Java™ 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-6u21-windows-i586-p.exe to install the newest version.



Step 2

Your Adobe Reader software is out of date and has known security holes. Please launch it, go to Help --> Check for Updates and let it update the main program if needed. Updates the languages and/or dictionaries is optional.



Step 3

Please pull anything out of the recycle bin that you want to save. Part of this fix will empty temp files, and that does include the recycle bin.

We need run an OTL Script

  7. You will get a log when it is done, please post that in your reply.
  8. Please then create a new OTL report....
  9. Click the "Scan All Users" checkbox.
  10. Push the button.
  11. A report will open, copy and paste it in a reply here.



Step 4

I'd like us to scan your machine with ESET OnlineScan
  1. Hold down Control and click on the following link to open ESET OnlineScan in a new window.
    ESET OnlineScan
  2. Click the button.

    2. Double click on the icon on your desktop.
  4. Check

  9. ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  10. When the scan completes, push
  11. Push , and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.

How is it running now? Please run a DDS scan for me:
  • Download DDS by sUBs from one of the following links. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explaination 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.

Hello, stu80.

Well, that website is legitmate and safe according to SiteAdvisor. So, two things could be happening. 1. False Positive. 2. Their website is hacked. 3. It's coming from an ad on their website. Those detections are you in your Internet Explorer cache. Since your a/v is picking it up, it should be okay.


Ok, good news. Your log appears clean. Let's clean up our mess. If your computer is running well; please do the steps listed below. At the end, I've also listed a few completely optional things you can do to further secure your computer. Safe surfing!



Step 1

Uninstall ComboFix and Clean Up
Click Start > Run and type combofix /Uninstall click OK (Note the space between combofix and /Uninstall) See below:

Please advise if this step is missed for any reason as it performs some important actions.

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.
  • If that link doesn't work, try this one.
  • Double click icon to start the program. If you are using Vista, please right-click and choose run as administrator
  • Then Click the big button.
  • You will get a prompt saying "Begin Cleanup Process". Please select Yes.
  • Restart your computer when prompted.



Step 2

Click Start --> Run and copy and paste the bold text into the box and press OK.
maxlook -cleanup

If you ran Defogger and disabled your emulator, please don't forget to run it again and reenable it. See the instructions here to do so.


Optional Items

Please take the time to read below to secure your machine and take the necessary steps to keep it that way.


System Still Slow?
You may wish to try StartupLite. Simply download this tool to your desktop and run it. It will explain any optional auto-start programs on your system, and offer the option to stop these programs from starting at startup. This will result in fewer programs running when you boot your system, and should improve preformance. If you are running Windows Vista or Windows 7, please right-click on the icon, and select "Run As Administrator"; otherwise it won't work.
If that does not work, you can try the steps mentioned in Slow Computer/browser? Check Here First; It May Not Be Malware

Protect yourself from malicious sites

The HOSTS file can protect you from connecting to bad sites. See The Hosts File and what it can do for you for more background.

Please download HostMan. It safeguards you with a regularly updated Hosts-file that blocks dangerous sites from opening. This adds another bit of safety while surfing the Internet. For installlation and setting up, follow these steps:
  1. Double-click the Downloaded installer and install the tool to a location of your choice
  2. Via the Startmenu, navigate to HostsMan and run the program.
    1. Click "Hosts" in the menu
    2. Click "Manage Updates" in the submenu
    3. Out of the three, select atleast one of the three (I have MVPS Host as my main one)
    4. Click "Add Update." After that you will only need to click on the following button to retrieve updates:
  3. Click the X to exit the program.
  4. Note: If you were using a custom Hosts file you will need to replace any of those entries yourself.


Keep Windows Up to Date
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.



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.

Use a Firewall

I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is susceptible to being hacked and taken over. I am very serious about this and see it happen almost every day with my clients. Simply using a Firewall in its default configuration can lower your risk greatly.

For a tutorial on Firewalls and a listing of some available ones see the link below:

Understanding and Using Firewalls

Install an AntiSpyware Program

A highly recommended AntiSpyware program isMalwarebytes Anti-Malware. You can download the free version..

Installing this 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.

Update all these programs regularly
Make sure you update all your programs regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.

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

Good luck!
