Defendsearch.com Redirect

Also Known As: Defendsearch.com browser hijacker
Damage level: Medium

What is defendsearch.com?

There are many fake search engines that are virtually identical to defendsearch.com, for example: resultsinquire.com, trackpackage.world and advisurf.com. It might look very similar to other well known search engines such as Google, Yahoo and so on.

However, this one is being promoted using rogue download and/or installation set-ups that are designed to modify browser's settings without user's consent. Besides, it also collects information related to its users browsing habits and causes redirects to questionable, untrustworthy web pages.

defendsearch.com browser hijacker

Typically, the aforementioned rogue set-ups target web browsers such as Google Chrome, Mozilla Firefox and Internet Explorer. They adjust browser's settings such as default search engine, homepage and new tab URL.

In this case all these options get changed to defendsearch.com, which means users of the hijacked web browser are forced to visit this fake search engine (its website) when a new browser tab, new window is opened, or a search query into the URL bar is entered.

It is impossible to undo these changes because rogue set-ups usually install so called "helper objects" (apps that are being installed into browsers) that are designed to reassign the appointed settings once an attempt to undo them is made. It can be done only when the aforementioned browser apps are uninstalled.

Besides, both defendsearch.com and "helper objects" are very likely to be designed to track (collect) data such as IP addresses, search queries, geo-locations, URLs of visited websites and other browsing-related information. It is also possible that some of the gathered data might include personal details as well.

Additionally, all the obtained data is constantly shared with third parties who use (misuse) it to generate revenue. That is why we do not recommend to use any fake search engine and to uninstall all the installed unwanted applications.

Such search engines usually are being promoted as useful, capable of providing their users with things such as more accurate search results, faster searches and so on. Unfortunately, these promotions are simply attempts to give an impression of legitimacy and to trick people into using these search engines.

Quite often they do not deliver any of the promised functionalities and are designed only to generate revenue for their developers. Besides, using such fake search engines might result in various problems related to browsing safety, privacy, increased risk of having a computer infected with some virus and so on.

How did defendsearch.com install on my computer?

As we mentioned earlier, developers of the defendsearch.com fake search engine promote it using rogue downloaders and/or installers. By using them they often successfully trick people into allowing these set-ups to make changes in their browser's settings. To install various potentially unwanted apps (PUAs) developers use a so called "bundling" method.

It is a method used to trick users into installing these apps together with some other software. Information about such apps being bundled into installation or download set-ups is usually hidden in "Custom", "Advanced" and other similar settings.

However, PUAs cannot be installed without giving them a permission for it. In other words, even if users install unwanted apps unintentionally, they do it by themselves.

How to avoid installation of potentially unwanted applications?

To prevent inadvertent installations (and changes in browser's settings) always download software from official and trustworthy websites or other sources. Avoid using third party software downloaders, installers, torrent clients and other peer-to-peer networks.

Do not forget to check "Custom", "Advanced" and other similar settings of the download or installation procedures and opt-out various potentially unwanted, bundles apps. Be careful when browsing the web, avoid clicking various intrusive advertisements.

These ads might look legitimate (their developers invest money in their design), however, they often cause redirects to various untrustworthy websites (such as gambling, adult dating, pornography and so on).

If you get redirected to suspicious websites often or are being served with lots of intrusive ads: check what are the installed extensions, add-ons or plug-ins on your web browser and programs on your computer. Remove all the unwanted/unknown or suspicious entries as soon as possible.

If your computer is already infected with browser hijackers, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate it.
