What Does the Destyy.com Browser Hijacker do?
Destyy dot com is the name of a browser extension that functions as a browser hijacker and exhibits some features typical for adware.
It can both alter your browser's settings and change your default search engine and home page, as well as change the content of pages you browse, injecting ads into them or causing a lot of pop-up ads to show up.
This sort of behavior is typical for browser hijackers. Browser hijackers are a category of a potentially unwanted program, usually distributed in the guise of a browser extension that claims to have some sort of useful functionality.
Hijackers will often store info on your search queries and browsing behavior and this can be a risk to your online privacy. Additionally, they can often alter the contents of pages you visit and inject ads into them. Those ads are often sourced through rogue ad networks, which means the ads may link to unsafe locations, questionable content or misleading websites.
Removing browser hijackers from your system is your best option. This is usually done through the browser's extensions or addons menu, as few browser hijackers have good persistence mechanisms.
