Get rid of unwanted redirects to search.schooldozer.com

Also Known As: Schooldozer browser hijacker
Type: Mac Virus
Damage level: Medium

What is search.schooldozer.com?

search.schooldozer.com is a fake web search engine identical to search.pitchofcase.com, search.zanzibog.com, and many others.

By offering improved search results, search.schooldozer.com attempts to give the impression of legitimacy, however, this site is promoted using browser-hijacking applications and download/installation set-ups designed to modify browser options without permission. Furthermore, search.schooldozer.com continually records various data relating to browsing activity.

Rogue apps and set-ups target Safari, Mozilla Firefox, and Google Chrome. Immediately after infiltration, they stealthily assign the web browser options (new tab URL, default search engine, and homepage) to search.schooldozer.com. These changes may seem insignificant, but users are unable to revert them.

Research shows that browser-hijacking apps and "helper objects" (third party apps/browser plug-ins stealthily installed by rogue set-ups) reassign browser options when attempts are made to change them.

Therefore, returning browsers to their previous states becomes impossible and users are forced to visit search.schooldozer.com when they open a new browser tab or search via the URL bar. This significantly diminishes the overall web browsing experience. It is also worth noting that search.schooldozer.com, as an Internet search engine, is completely useless.

All it does is redirects users to search.yahoo.com every time a query is entered. In other words, search.schooldozer.com does not generate any results by itself and users merely end up searching the web via Yahoo search engine. Another important issue is information tracking.

Be aware that "helper objects", browser-hijacking apps, and search.schooldozer.com continually gather various information such as IP addresses, URLs visited, pages viewed, keystrokes, geo-locations, and so on. The information might contain personal details that developers share with third parties.

These people (potentially, cyber criminals) misuse private data to generate revenue. Therefore, data tracking can lead to serious privacy issues or even identity theft. If you encounter redirects to search.schooldozer.com, immediately eliminate all dubious applications/browser plug-ins and never return to search.schooldozer.com

The Internet is full of fake web search engines such as search.schooldozer.com. By offering improved search results and, sometimes, other "useful features" (shortcuts to popular sites, weather forecasts, and so on), websites such as search.schooldozer.com attempt to trick users into believing that they are legitimate and useful.

In fact, the only purpose of all fake search engines is to generate revenue for the developers. Rather than giving any real value for regular users, these sites cause unwanted redirects and gather sensitive information.

In some cases, they generate false search results and intrusive ads (e.g., banners, coupons, etc.) that typically lead to untrustworthy websites. Therefore, using fake web search engines can lead to various system infections.

How did search.schooldozer.com install on my computer?

As mentioned above, search.schooldozer.com is promoted using rogue set-ups. This deceptive marketing method is called "bundling". Developers know that users are likely to rush download/installation processes and skip steps. Therefore, all details regarding modification of browser settings are hidden within "Custom/Advanced" options of these procedures.

By rushing and skipping steps, users inadvertently grant set-ups permission to modify browser options. Browser-hijacking apps are also distributed using the "bundling" method (and intrusive advertisements). As mentioned, after stealth system infiltration, PUPs change browser options.

How to avoid installation of potentially unwanted applications?

The main reasons for computer infections are poor knowledge and careless behavior - the key to safety is caution. Therefore, pay close attention when browsing the Internet and, especially when downloading/installing software. Bear in mind that intrusive ads often seem legitimate, but most lead to gambling, adult dating, pornography, and other dubious websites.

In most cases, they are delivered by adware-type PUPs, and thus, if you encounter them, immediately remove all suspicious applications and browser plug-ins. Furthermore, select "Custom/Advanced" settings and carefully analyze each step of the download/installation processes.

Decline offers to download/install additional applications and cancel those already included. We also recommend that you download your software from official sources only via direct download links, rather than using third party downloaders/installers. These tools are typically monetized by promoting PUPs, and thus, these tools should never be used.
