Request visitors' permission before installing software

Webmaster Level: All
Legitimate websites may require that their visitors install software. These sites often do so to provide their users with additional functionality beyond what's available in standard web browsers, like viewing a special type of document. Please note, however, that if your site requires specific software for your visitors, the implementation of this software installation process is very important. Incorrect implementation can appear as though you're installing
malware
, triggering our malware detection filters, and resulting in your site being labeled with a 'This site may harm your computer'
malware warning
in our search results.
If using your site requires a special software install, you need to first inform visitors why they need to install additional software. Here are two bad examples and one good example of how to handle the situation of a new visitor to such a site:
Bad: Install the required software without giving the visitor a chance to choose whether or not they want to install the software.
Bad: Pop up a confirmation dialog box that prompts the visitor to agree to install the software, without providing enough detail for the visitor to make an informed choice. (This includes the standard ActiveX control installation dialog box, since it doesn't contain enough meaningful information for a visitor to make an informed decision about that particular piece of software.)
Good: Redirect the new visitor to an information page which provides thorough details on why a special software installation is required to use the site. From this page the visitor can initiate the installation of the required software if they decide to proceed with installation.
Has your site been labeled with a malware warning in our search results due to a poorly implemented software installation requirement? Updating the installation process to ensure that visitors are fully informed on why the installation is necessary, and giving them a chance to opt out, should resolve this issue. Once you've got this in place, you can go to
Webmaster Tools
and request a
malware review
to expedite the process of removing any malware warnings associated with your site in Google's search results.
