Hello!

I am using Windows 7, and I just purchased SUPERAntiSpyware Professional because, whenever I'd try to follow a result on Google, I'd be redirected to internet error pages with addresses like directdr.com.
My default browser is Mozilla Firefox (though IE8 is still installed on this computer)

Here is a log of the scan I finished perhaps 30 seconds ago:

Hello and welcome to Bleeping Computer.

Please subscribe to your topic so that you will be notified as soon as I post a reply, instead of you having to check the topic all of the time. This will allow you to get an email notification when I reply.

To subscribe, go to your topic, and at the top right hand corner by your first post, click the Options button and then click Track this topic. The bullet the immediate notification bubble. Then press submit.


Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

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.

Double Click zztoy.exe to install the application.
* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

It seemed that stopped after I got SUPER AntiSpyware, but I just experienced a popup when I went to Google. The popup concerned a Google survey.
I can't tell that there's anything wrong (but, then again, from what I just briefly read, that's the nature of backdoor.bots - quiet and in the background). The redirecting still happens, though not as much as before, and the only time I can tell there was something wrong is when I run a scan.

So... I'm not sure if the problem is solved. Should I run another scan perhaps?

Since you still have the redirect, then let's check for rootkits.

Please install RootRepeal

Go HERE, and download RootRepeal.zip to your Desktop.
Tutorial with images ,if needed >> L@@K
Unzip that to your Desktop and then click RootRepeal.exe to open the scanner.

*Open the folder and double-click on RootRepeal.exe to launch it. If using Vista, right-click and Run as Administrator...
* Click on the Report tab, then click the Scan button. Check all seven of the boxes.
* In the Select Drives, dialog Please select drives to scan: select all drives showing, then click OK.
* When the scan has completed, a list of files will be generated in the RootRepeal window.
* Click on the Save Report button and save it as rootrepeal.txt to your desktop or the same location where you ran the tool from.
* Open rootrepeal.txt in Notepad and copy/paste its contents in your next reply.
* Exit RootRepeal and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.

Please note: If Rootrepeal fails to run, try this step: Click Settings - Options. Set the Disk Access slider to High


Note 2: If RootRepeal cannot complete a scan and results in a crash report, try repeating the scan in "Safe Mode".

Hey ComputerPro!

I've included the error message I receive when I try to run the program:

Posted Image

Maybe it has something to do with this upgrade to Windows 7. I have a lot of compatibility issues, it seems.

I actually don't think it's compatable yet, so lets run another scanner:

Ok, please follow the instructions here for running the ESET online scanner:

Please perform a scan with ESET Online Scanner
(Requires Internet Explorer to work. If given the option, choose "Quarantine" instead of delete.)
Vista Users be sure to run Internet Explorer as Administrator. To do this, right-click on the IE icon in the Start Menu or Quick Launch Bar on the Taskbar and select "Run as Administrator" from the context menu.)

You will see the Terms of Use. Tick the check-box in front of YES, I accept the Terms of Use

Now click Start.

You may receive an alert on the address bar that "This site might require the following ActiveX control...Click here to install...". Click on that alert and then Click Insall ActiveX component.

A new window will appear asking "Do you want to install this software?" (OnlineScanner.cab)".
Answer Yes to install and download the ActiveX controls that allows the scan to run.

Click Start. (the Onlinescanner will now prepare itself for running on your pc)

To do a full-scan, check: "Remove found threats" and "Scan potentially unwanted applications"
Press Scan to start the online scan. (this could take some time to complete)
When the scan has finished, it will show a screen with two tabs "overview" and "details" and the option to get information or buy software. Just close the window.

Now click Start > Run... > type: C:\Program Files\EsetOnlineScanner\log.txt

The scan results will open in Notepad.

Copy and paste the log results in your next reply.


Note: Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn\ them back on after you are finished.

I tried to run the "C:/Program Files..." but it couldn't find that.

But I can say that it found nothing during this scan.

Ok, and lets try Sophos:

Please download Sophos Anti-rootkit& save it to your desktop.
Note: If using the vendor's download site you will be asked to register with MySophos so an email containing an activation link can be sent to your email address.

Credits to DaChew
Be sure to print out and read the User Manualand Release Notes
Double-click sar_15_sfx.exe to begin the installation, read the license agreement and click Accept.
Allow the default location of C:\Program Files\Sophos\Sophos Anti-Rootkit and click Install.
A message will appear "Sophos Anti-Rootkit was successfully installed. Click 'yes' to start it now". Click Yes.
Make sure the following are checked:
o Running processes
o Windows Registry
o Local Hard Drives

Click Start scan.
Sophos Anti-Rootkit will scan the selected areas and display any suspicious files in the upper panel.
When the scan is complete, a pop-up screen will appear with "Rootkit Scan Results". Click OK to continue.
Click on the suspicious file to display more information about it in the lower panel which also includes whether the item is recommended for removal.
o Files tagged as Removable: No are not marked for removal and cannot be removed.
o Files tagged as Removable: Yes (clean up recommended) are marked for removal by default.
o Files tagged as Removable: Yes (but clean up not recommended) are not marked for removal because Sophos did not recognize them. These files will require further investigation.
Select only items recommended for removal, then click "Clean up checked items". You will be asked to confirm, click Yes.
A pop up window will appear advising the cleanup will finish when you restart your computer. Click Restart Now.
After reboot, a dialog box displays the files you selected for removal and the action taken.
Click Empty list and then click Continue to re-scan your computer a second time to ensure everything was cleaned.
When done, go to Start > Run and type or copy/paste: %temp%\sarscan.log
This should open the log from the rootkit scan. Please post this log in your next reply. If you have a problem, you can find sarscan.log in C:\Documents and Settings\<username>\Local Settings\Temp\.
Before performing an ARK scan it is recommended to do the following to ensure more accurate results and avoid common issues that may cause false detections.
Disconnect from the Internet or physically unplug you Internet cable connection.
Clean out your temporary files.
Close all open programs, scheduling/updating tasks and background processes that might activate during the scan including the screensaver.
Temporarily disable your anti-virus and real-time anti-spyware protection.
After starting the scan, do not use the computer until the scan has completed.
When finished, re-enable your anti-virus/anti-malware (or reboot) and then you can reconnect to the Internet.

It is okay that "Running Processes" has a shaded box by it? I can check "Windows Registry" and "Local Hard Drives." There's no box for me to check by "Running Processes," just a shaded box.

How can I do that if I can't remove anything (since nothing was recommended for removal)?
