For a few weeks now I've been experiencing some very annoying pop-up ads, mostly titled "Powered by Zedo". Sometimes an annoying web page will open which looks like a news website as well. I've run antivirus programs and spyware blockers, to no avail. Below is a current HJT log. Any help is greatly appreciated! Thanks, Steve

Quick summary: the "Powered by Zedo" pop-ups are typically delivered by adware that persists as a browser component plus one or more autostart entries. Disabling the visible add-on (as suggested) can stop immediate pop-ups, but a complete cleanup usually requires removing leftover files, startup entries, and any scheduler/service hooks that re-enable the component.

Recommended next steps (in order):

  1. Boot to Safe Mode (with Networking if you need to download tools) and update your scanners.
  2. Run an up-to-date adware-focused scanner (for example, Malwarebytes) and an on-demand cleaner. Let each tool remove what it finds, then reboot and re-scan.
  3. Use Autoruns (Sysinternals) to inspect all autostart locations (startup, scheduled tasks, services, shell extensions). Uncheck suspicious entries and use "Jump to" to verify the file path before deleting.
  4. Check Programs (Add/Remove) for unfamiliar installs and uninstall them. Inspect scheduled tasks and non-Microsoft services for anything odd.
  5. Reset network-related hooks: clear browser temp files and settings, and run netsh winsock reset followed by a reboot to remove LSP/Winsock hijacks.
  6. After cleanup, update the browser/plugins and run one final full scan.

Cautions and follow-up: create a System Restore point or export registry keys before manual removals. Avoid deleting files unless their purpose is known. If the adware persists, consider an offline rescue scanner (bootable rescue disk) and submit suspicious files to VirusTotal for analysis. If further help is needed, post a fresh Autoruns or log file and list which removal steps and tools were already tried so responders can focus on remaining persistence mechanisms.

References: Malwarebytes and Autoruns (Sysinternals).

open IE
goto tools
goto manage addons
click on the werweb registry entry
click on disable

Thanks, I was unaware of the "managing add-ons" option on IE. I'll let you know if I still have a problem!
