Hi guys! I'll try to be as complete as I can.

Yesterday, while searching the internet for some info about an svg attribute, I must have run into some spyware. AVG alerted me to two Agent_r.SI infections, a 505.tmp in C:\Windows\temp\ and another .exe in a location I cannot recall. Both were quarantined, but I quickly saw symptoms of the infection continue to manifest:

- Browsers (IE and Firefox) redirecting search link results from google
- Browsers blocking access to certain websites (ESET and Kapersky online scanners, for instance).
- Previously unable to run Malwarebytes Anti-Malware or SuperAntiSpyware (I can now, but cannot update my definitions MBAM, and had to update SAS manually from another computer)

I've been pretty good about avoiding and removing viruses in the past, but this one has me stumped. Here are the steps I've already taken to remove the infection, more or less in order:

1. Ran a full AVG scan. Cleaned the above files located in my Windows\temp directory. Rebooted, and found they had been replaced.
2. Ran Process explorer and killed a certain process with a garbage name under the "company" field -- I was then able to start up MBAM. I Also killed Llr.exe and Llq.exe found within my Windows\temp folder.
3. Deleted the above files through explorer. Cleaned out my Windows\temp folder completely.
4. Ran SuperAntiSpyware via the alternate execution shortcut, scanned and removed an Adware.Vundo/Variant and an Unclassified.Unknown Origin.
5. Ran MBAM. Results came up clean.
6. Ran HijackThis!. Scan provided no useful (to me) information as I'm inexperienced in interpreting the log.
7. Following advice for a similar infection on another forum, ran CCleaner, TDSSKiller, ComboFix, rootrepeal. One infection was found and cleaned with TDSSKiller. Re-scanning after a reboot did not find anything. Following this forum's preliminary advice, I've run DeFogger and DDS, and I am currently running GMER, and will update this post with my log once it finishes scanning.

So here is my current situation:
- Browsers still occasionally redirect google search results
- Browsers still block some websites, particularly online virus scanners
- AVG, MBAM, and SuperAntiSpyware will not update from within the program itself, and must be done so manually (However, MBAM will crash and require a reinstall if I try)

Attached are logs from ComboFix, DDS, and recent ones from HijackThis and Rootrepeal. I will upload a GMER log shortly. Edited to include GMER log.

Thank you!

Hello ,
And welcome.gif to the Bleeping Computer Malware Removal Forum
. My name is Elise and I'll be glad to help you with your computer problems.

I will be working on your malware issues, this may or may not solve other issues you may have with your machine.

Please note that whatever repairs we make, are for fixing your computer problems only and by no means should be used on another computer.
  • The cleaning process is not instant. Logs can take some time to research, so please be patient with me. I know that you need your computer working as quickly as possible, and I will work hard to help see that happen.
  • Please reply using the Add/Reply 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.
  • Unfortunately, if I do not hear back from you within 5 days, I will be forced to close your topic. If you still need help after I have closed your topic, send me or a moderator a personal message with the address of the thread or feel free to create a new one.
You may want to keep the link to this topic in your favorites. Alternatively, you can click the button at the top bar of this topic and Track this Topic, where you can choose email notifications. The topics you are tracking are shown here.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.

If you have already posted a log, please do so again, as your situation may have changed.
Use the 'Add Reply' and add the new log to this thread.

We need to see some information about what is happening in your machine. Please perform the following scan:
  • Please download OTL from one of the following mirrors:
  • Save it to your desktop.
  • Double click on the icon on your desktop.
  • Click the "Scan All Users" checkbox.
  • Push the button.
  • Two reports will open, copy and paste them in a reply here:
    • OTListIt.txt <-- Will be opened
    • Extra.txt <-- Will be minimized

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.
-- If you encounter any problems, try running GMER in Safe Mode.

In the meantime please, do NOT install any new programs or update anything unless told to do so while we are fixing your problem

If you still need help, please include the following in your next reply
  • A detailed description of your problems
  • A new OTL log (don't forget extra.txt)
  • GMER log

Thanks and again sorry for the delay.

regards, Elise
