On all my browsers (internet explorer,google chrome, firefox) every website that has a ad won't load it. on the youtube homepage where the ad goes it's either blank or it says on google something like " connection to ad.adclick was rejected" I don't have any ad blockers.The problem is its making all internet slow cause it's trying to load the ad and won't load anything until it fails to load ad. I checked host file and it's normal. Something is denying ads in my pc. On my other pc everything works normal using the same router. A toolbar installed itself without me knowing and I think after that it started messing up. I uninstalled it but it didn't fix problem. Any help would be appreciated

I already ran eset scanner but it didn't fix

The 502 Bad Gateway error is usually a network error between servers on the Internet, meaning the problem isn't typically with your computer or Internet connection.

Lets run two other tools first.
Please Download TDSSkiller
Launch it.
Click on change parameters-Select TDLFS file system
Click on "Scan".
Please post the LOG report(log file should be in your C drive)

Do not change the default options on scan results.




Please download Malwarebytes Anti-Malware Posted Image and save it to your desktop.
  • Important!! When you save the mbam-setup file, rename it to something random (such as 123abc.exe) before beginning the download.
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.

  • Make sure you are connected to the Internet and double-click on the renamed file to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • Malwarebytes 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 and continue.
  • 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.
  • Under the Scanner tab, make sure the "Perform Quick Scan" option is selected.
  • Click on the Scan button.
  • When the scan is complete, click OK, then click the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked and then 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.
  • 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.
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).

I did those both just earlier today and they found nothing, But the problem is the my computer, cause my other pc loads all ads fine. I went through settings and found that the ip protocol 4 or something like that was set to connect to a certain dns server, instead of automatically connect. I think that has fixed the problem but I will have to wait and see.

You should repost this then in the Operating system forum up top as it is not malware.
