The Dogpile Redirect is a symptom of various browser hijackers, especially ones associated with certain toolbars and other browser add-ons for Internet Explorer. Dogpile Redirect attacks may lock either your homepage or your default search engine to Dogpile.com, a seemingly functional search site that, regrettably, has a history rich in associations with low-level PC threats. Although protected and limited contact with the search results promoted through a Dogpile Redirect attack isn't likely to be a major security issue, malware experts still suggest deleting any add-on that causes Dogpile Redirects as a primary function. To be certain of removing both all related browser changes and any other associated PC threats, using anti-malware products for the disinfection process should be taken as common sense.

When Your Browser is Being Dogpiled from Unexpected Sources

The Dogpile Redirect problem is associated with multiple browser toolbars, including the (currently discontinued) DogPile toolbar and SearchTape, a general search engine utility that has been bundled with other programs, such as Contactier (a social networking contacts utility). Although all of these programs seem safe on a surface inspection, malware researchers found some unhappy surprises when looking into the histories of the related sites and companies. The DogPile toolbar has been warned to include invasive browser-tracking functions, and both DogPile and SearchTape are classified as adware. The DogPile toolbar also is categorized as a browser hijacker. Finally, sites associated with either of these products have been known to distribute a variety of low-level PC threats and, in rare cases, links towards phishing attacks.

The promotion of phishing attacks is, perhaps, most relevant to the issue of a Dogpile Redirect – since phishing attacks easily may be disguised within search results. While malware experts currently see no signs of Dogpile.com continuing past unsavory efforts, they do warn that any interaction with content related to a Dogpile Redirect should be undertaken with a significant degree of caution.

Dogpile Redirects, themselves, easily are detected from their perpetual tactics of forcing your browser to load Dogpile.com, as well as the fact that the programs they're associated with predominantly are browser toolbars with distinctly visible components.

Pulling Your Browser out of a Pile of Unhelpful Software

If you practice safe browsing habits, avoid potentially threatening website links (such as fraudulent software updates or phishing attacks disguised as surveys) and use appropriate PC security software, a temporary Dogpile Redirect problem shouldn't be able to harm your computer in any meaningful way. However, given Dogpile.com's past, Dogpile Redirect attacks should be resolved as soon as it's convenient, rather than ignored as a non-threat to the safety of your browser or the rest of your PC.

Although Dogpile.com does offer uninstall instructions for software that causes Dogpile Redirect problems, malware researchers advise against using this 'official' method of uninstalling related PC threats. To be as certain as possible that all components of a Dogpile Redirect hijacker have been deleted entirely, using anti-malware software to examine your computer is preferred as the most reliable disinfection method.
