Hello. (I hope that I am posting this in the right location!)


Recently, I have come across a virus on my IE browser's main url line, which is what I use as a search bar. While its default search engine is Bing, and looks like it might search through Bing, it redirects me to a search engine with a Time Warner Cable logo called dnsrsearch. I don't have this problem with Firefox, which is what I mostly use, but I am worried that this might be bad if gone unchecked.


I am on a Windows 7, x64-bit.


I've had search engine redirect viruses before (and pretty tough ones over the summer), where the actual results of any search engine would redirect (All solved, and all thanks to the wonderful people of Bleeping Computer!), but this is the first one where the actual search engine was redirected.


If anyone can help me with this, I would be very grateful!

Hello Aurum.
First look in toolbars, plugins, extensions, add-ons
Internet Explorer
Go to TOOLS and then click MANAGE ADD-ONs, From there, select Extensions, Toolbars and remove the Dnsrsearch.com if found. Make sure Google is set as default search Provider.
Uninstall Programs or Programs and Features, now lookup for Dnsrsearch.com and uninstall if it is listed.
Please download Malwarebytes Anti-Malware mbamicontw5.gif and save it to your desktop. %5BLIST%5D
  • Important!! When you save the mbam-setup file, rename it to something random (such as 123abc.exe) before beginning the download.
  • Double-click on the renamed file to install, then follow these instructions
  • for doing a Quick Scan in normal mode.
  • [/list] %5BLIST%5D
  • Don't forget to check for database definition updates through the program's interface (preferable method) before scanning.
  • If you cannot update Malwarebytes or use the Internet to download any files to the infected computer, manually update the database by following the instructions in FAQ Section A: 4. Issues
  • [/list] Malwarebytes 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. %5BLIST%5D
  • After completing the scan, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab .
  • 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 the database version and your operating system.
  • Exit Malwarebytes when done.
  • [/list] Note: If Malwarebytes encounters a file that is difficult to remove, you will be asked to reboot your computer so it can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally will prevent Malwarebytes from removing all the malware. -- Some types of malware will target Malwarebytes and other security tools to keep them from running properly. If that's the case, use Malwarebytes Chameleon and follow the onscreen instructions. The Chameleon folder can be accessed by opening the program folder for Malwarebytes Anti-Malware (normally C:\Program Files\Malwarebytes' Anti-Malware or C:\Program Files (x86)\Malwarebytes' Anti-Malware).

    ADW Cleaner

    Please download AdwCleaner by Xplode onto your desktop.
  • Close all open programs and internet browsers.
  • Double click on adwcleaner.exe to run the tool.
  • Click on Delete.
  • Confirm each time with Ok.
  • You will be prompted to restart your computer. A text file will open after the restart.
  • Please post the contents of that logfile with your next reply.
  • You can find the logfile at C:\AdwCleaner[S1].txt as well.

Thank you. I wanted to say that somewhere along the way, the problem simply disappeared!


I should have mentioned before that the exact same issue was happening on both of my computers both my old laptop that I don't mind venturing the Internet with, and my newer one that I'm a bit more cautious with, meaning that whatever caused it might have been from a website that I frequently visited, believing to be safe. I did your instructions on my older computer, but not on my newer computer, yet both seemed to have the problem disappear! I am curious what happened there, as the problem persisted for almost a couple of weeks. Thank you for your help! :)

dnsrsearch.com is not a virus on your computer. It is an annoying advertising site, to which Time-Warner's nameservers redirect failed DNS lookups.

It's the jerks at Time-Warner degrading their customers' service to generate ad revenue.


The solution is to configure your router (preferably) and/or your computer to use Google's nameservers instead of Time-Warner's.

Google's nameservers are and (good).

Time-Warner's nameservers are and (bad -- they LIE to you).


C:\>nslookup no-such-domain-as0o324kldklfgjk34lkfldf.com
Server:  google-public-dns-b.google.com
*** google-public-dns-b.google.com can't find no-such-domain-as0o324kldklfgjk34lkfldf.com: Non-existent domain
C:\>nslookup no-such-domain-as0o324kldklfgjk34lkfldf.com
Server:  dns-cac-lb-01.rr.com
Non-authoritative answer:
Name:    no-such-domain-as0o324kldklfgjk34lkfldf.com

Those addresses returned by Time-Warner's DNS are bogus! Their nameservers lie! The first ( doesn't work at all at the moment (result: a looooong pause). The second ( goes to the stupid dnsrsearch.com advertising page.

Here's a screenshot:
