D2sri.com is a Web page associated with Potentially Unwanted Programs (PUPs) for Windows and Mac. Users report seeing this page's URL briefly when trying to initialize a new Web search through the browser's address bar. The redirect to D2sri.com may often be accompanied by unwanted advertisements and pop-ups that will show up before the user is taken to Yahoo Search. Clearly, D2sri.com's presence in your Web browser is linked to a PUP that has modified your default search settings.

Users who experience unwanted redirects through D2sri.com should know that this is abnormal behavior, and they should try to get to the bottom of the issue as soon as possible. While this is not harmful behavior, it may be annoying because of the extra advertisements you will see. The best you can do to make sure that your browser's search settings have not been modified by external software is to run a reputable anti-virus product that will scan for Potentially Unwanted Programs (PUPs) and browser hijackers.

Avoiding problems of this sort requires the use of reputable security software, as well as being careful with the types of files you download and run. Avoid non-trustworthy extensions, pirated software and downloads from shady sources.
