Hello and welcome to the forums!

I'm SweetTech, pleased to meet you. I am very sorry for the delay in responding, but as you can see we are at the moment being flooded with logs which, when paired with the never-ending shortage of helpers, resulted in the delayed responding to your thread.
If you have already received help elsewhere please inform me so that this topic can be closed. If you have not, please adhere to the guidelines below and then follow instructions as outlined further below:

• Logs from malware removal programs (DDS is one of them) can take some time to analyze. I need you to be patient while I analyze any logs you post.
• Please make sure to carefully read any instruction that I give you.
  Reading too lightly will cause you to miss important steps, which could have destructive effects.
• If you're not sure, or if something unexpected happens, do NOT continue! Stop and ask!
• These instructions have been specifically tailored to your computer and the issues you are experiencing with your computer. It's important to note that these instructions are not suitable for any other computer, even if the issues are fairly similar.
• Do not do things I do not ask for, such as running a spyware scan on your computer. The one thing that you should always do, is to make sure sure that your anti-virus definitions are up-to-date!
• If I instruct you to download a specific tool in which you already have, please delete the copy that you have and re-download the tool. The reason I ask you to do this is because these tools are updated fairly regularly.
• I am going to stick with you until ALL malware is gone from your system. I would appreciate it if you would do the same. From this point, we're in this together
  Because of this, you must reply within three days. I will post a reminder should you seem to fail to do this, however, if you fail to reply within two days then,
  unless I have been notified of your absence in advance, the topic shall be closed!
• Lastly, I am no magician. I will try very hard to fix your issues, but no promises can be made. Also be aware that some infections are so severe that you might need to resort to reformatting and reinstalling your operating system.
  Don't worry, this only happens in severe cases, but it sadly does happen. Be prepared to back up your data. Have means of backing up your data available.

• Click the Run Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
  
• When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
• Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post it with your next reply.
• You may need two posts to fit them both in.

Scanning with GMER

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.

• GMER will open to the Rootkit/Malware tab and perform an automatic quick 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 re-enable all active protection when done.

Please make sure you include the following items in your next post:

1. Any comments or questions you may have that you'd like for me to answer in my next post to you.
2. The logs that were produced after running OTL. (OTL.txt & Extras.txt)
3. The log that was produced after running GMER. (GMER.txt)
4. An update on how your computer is currently running.

It would be helpful if you could answer each question in the order asked, as well as numbering your answers.

Thanks for your help Sweettech, but I reinstalled my OS. I will try to be more patient next time.

Okay. Thanks for letting us know. I'll go ahead and mark this as resolved.
