BrowserDefender Distribution Technique
BrowserDefender is usually downloaded together with other potentially unwanted programs. The process is called bundled downloading and is applied for financial purposes. Bundling may be escaped if the user opts for the custom installer and deselects suspicious applications. Frequently updating the present anti-malware tool is another safety measure.
BrowserDefender Description and Behavior
BrowserDefender promises to keep the browser safe from hijacking, but users should be alarmed since the PUP blocks not only third-party software but also Google and Bing. It may get in the way and prevent the user from changing his homepage or search provider.
Security experts also warn users to be careful if tempted to install BrowserDefender because it is suspected to collect private data. In summary, BrowserDefender may seem like a very useful program but as a matter of fact it may cause serious issues with the operating system. The PUP may also alter the browser’s settings to its likings so that the user is redirected to initially determined pages.
Due to the potential threats caused by the suspicious software, its removal is recommended.
