Spyware, Malware, Adware, or Virus Interfering with Steam
Spyware, malware, or adware is interfering with Steam's functionality.

Ads are appearing in the Steam browser or mouse clicks within Steam are opening external websites

Note:

Steam has a strict privacy policy and will not share your information with other companies. Steam's only advertisement popup will appear in an instant message that displays upcoming and new releases or changes to games that you own. If you would not like to see this instant message, you can disable it in Steam's settings menu.

If your computer has become infected with malware/adware that targets Steam, you may see one or more of the following issues:

  • Obvious garbage ads appear over the Steam application
  • An external application appears to be subtly hijacking clicks within the Steam application to send you to external advertisement websites
  • Ads are randomly appearing in Steam Web Browser windows
  • You are repeatedly seeing an error message that says "Access Denied: You don't have permission to access http://steamcommunity.com on this server."

Spyware, adware, virus, trojans and worms may directly impact your ability to access Steam - if you have exhausted other troubleshooting steps, or have noticed unexpected behavior and decreased performance on your machine, please download and install a spyware and adware scanner and a virus scanning utility.

Remove Virus, Trojans and Worms

The most common virus are transmitted through e-mail attachments, downloading files from resources that are not entirely trusted, or peer-to-peer (P2P) file trading applications such as BitTorrent. With any Anti-Virus program, it is important to keep Anti-Virus definitions updated and run a system scan regularly.

Remove Malware, Spyware, or Adware

A common source of Spyware/Adware is installing unknown software from untrusted websites. These programs can cause system slowdown and/or connectivity problems.

Some malware removal tools may interfere with Steam - make sure that you set up the application appropriately and create exceptions for Steam and its games. If you need help creating an exception, please contact the security software's support team for specific instructions.

Important:

When searching for or choosing a malware removal tool, make sure to research the tool before making a decision. Download the tool only through official, trusted websites. Many self-described malware removal tools are actually malware themselves.
