Hi! My computer is infected. Sometimes when I try to access a web site, I'm diverted to a Dell page and a message appears that says Sorry, we couldn't find htt*p://ad.yieldmanager.com/st%3Fad_type." It doesn't happen all the time and it does not appear to be specific to one particular site.

I've already done the following, but ad.yield manager is still there.

I've run "cleanmgr" and scanned my computer with Ad-Aware, Spybot Search and Destroy, Bit Defender (nothing found), Housecall Antivirus (nothing found), Deckard's System Scanner (I have the log) and Kasperdsky Online Scanner (nothing found).

Please help!

Hello heat662,(Im am not a professional but I know alot about viruses) please download the latest version of HijackThis from http://www.trendsecure.com/portal/en-US/to...ckthis/download. preferrably the executeable. Then run it and click on Open the misc tools section. Then go to open process manager and look for bidispl6.exe. It it is there then kill the process. If it is not there I don't know what to do but if you did fuind it follow the next steps.
Then click on main menu and click do a system scan only. Then check if there is R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = file://C:\WINDOWS\system32\Searchx.htm
O4 - HKLM\..\Run: [9add269de125] C:\WINDOWS\system32\bidispl6.exe
If there is tick the box next to those to and click fixed checked. After that when you fixed it, Go to My Computer, Local disk, WINDOWS then delete Searchx.htm and bidispl6.exe.

Well, I ran HijackThis and did not see bidispl6.exe, nor any of the other things you mentioned. I guess I'll surf the net and see if I get ad.yield manager again! Thanks for your help.

I thin you should try to contact (eg. PM) an expert in BleepingComputer.

After doing a lot of research about ad.yieldmanager, I've learned it is a tracking cookie that can keep coming back even after you've removed some of the bad stuff from your system. It can come back when you visit certain web pages. For me, it's been ebay.com and a univision.com web page.

Cookies are text files placed on your computer by various sites that you visit either directly (first-party) or indirectly (third-party). A cookie can contain any data that a site wishes to store. It is often used to track your computer as you move through a web site and store information such as preferences or credentials.

Another help site suggested changing my web browser security to minimize cookies.

So I went here... http://www.us-cert.gov/reading_room/securing_browser/ and made some of the changes they suggested. I say some because when I set my browser security to High, I wasn't able to run some programs or access some websites. For example, when I logged into to the bleepingcomputer forum and came to this thread, it wouldn't let me make a post. And when I went to login into my Imageshack account, it wouldn't recognize me. But when I set the security to Medium and added Imageshack to my allowed sites under Privacy, those problems went away.

After making these changes, this is what I got when I went to ebay (see screen capture)... http://img185.imageshack.us/img185/9753/adyieldebayro2.jpg
It asks if I want to allow the ad.yieldmanager cookie!!! So I clicked "No" to deny it, and was able to surf ebay without any more problems from ad.yield manager.

Not sure if this is a definite fix... only time will tell.

Hi and welcome, two things first.
Are you runnng XP or another?
You should not be using HiJackThis without expert assistance. stopping the wrong operation with it can render your PC unbootable.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
  • MBAM will automatically start and you will be asked to update the program before performing a scan. If an update is found, the program will automatically update itself. Press the OK button to close that box and continue. If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
  • On the Scanner tab:
    • Make sure the "Perform Quick Scan" option is selected.
    • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
  • Back at the main Scanner screen, click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Reagardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.
