Catstart.com developers take advantage of cat lovers
Catstart.com functions as a fraudulent search engine which supposedly should make your browsing experience better. This potentially unwanted program is decorated with cat wallpapers that change hourly/daily/randomly to trick pet-friendly people to use its services. However, experts warn that it can hijack Chrome and other popular browsers once you install Cat Start extension.
Inexperienced computer users might not be aware, but Cat Start hijack may put your privacy at risk. This browser hijacker alters your regular browser settings and sets itself to the new tab, homepage, and default search engine. Additionally, it infiltrates other add-ons which do not allow you to reset the parameters mentioned above.
Shortly after, Catstart.com starts to collect various information about the new user, such as IP address, clicked ads, browser history, etc. Even though this information is personally non-identifiable, you might be tricked to give in personal details via surveys, contests and other ways[1].
Besides, users report that once they have installed Cat Start Chrome extension, they noticed a significant increase in commercial content during their browsing sessions. In other terms, this potentially unwanted program serves its users with numerous banners, pop-ups, and in-texts.
Even though this activity might seem only annoying, you can accidentally harm your computer due to Catstart.com redirect as well. It is because this browser hijacker does not take responsibility for the content of the ads it promotes and malevolent people take advantage of it.
Thus, some of the delivered advertisements which you might find among the search results can be potentially malicious. It means that clicking on them may either directly infiltrate malware or lead to a shady website. Likewise, experts from NoVirus.uk[2] recommend you not to click on any types of ads online and remove Catstart.com.
Since this browser hijacker comes together with additional elements, it might be hard to get rid of it. Therefore, we suggest using FortectIntego or any other robust anti-spyware software for Catstart.com removal. Additionally, you can learn how to reset your browser after the procedure to the primary stage from the guide below.
The contrivers use a popular marketing method to distribute browser hijackers
The primary distribution way how the developers of browser hijacker and other potentially unwanted programs spread their products is called bundling[3]. They put the PUP inside the package of the regular applications and offer them as one without fully disclosing the information.
While many people choose Quick/Recommended settings, they are unable to detect the browser hijacker and manually install it together with freeware. Likewise, it is extremely important to monitor each step of the installation/download process. For that, pick Custom/Advanced parameters and search for checkmarks like “Get XXX now.”
Afterward, you should de-select those marks and use a reputable antivirus software to double-check your system. Additionally, do not click on commercial content online since browser hijackers might also spread on suspicious websites or malware-laden ads.
