Drop Extension

Drop Extension is an app that appears like a regular browser add-on but instead of working like one, it takes over the browser and loads it up with hard-to-remove advertisements. Drop Extension can often unexpectedly redirect the users’ searches to pages that pay for their traffic and add-supported sites.

Drop Extension

The ultimate purpose of apps like Drop Extension is not to harm your PC or undermine your computer’s safety, as you may initially think, but only to promote certain websites and to generate clicks on their sponsored commercial messages. In a way, this is good news because if you have recently detected this browser hijacker on your machine, then you aren’t dealing with some dangerous Trojan, a Ransomware or some other form of destructive computer virus that needs to be removed.

The browser hijackers aren’t built to cause damage to the users and their systems. Yet, it is a good idea to uninstall them from your browser (be it Chrome, Firefox, Edge or any other) since the modifications they tend to make to the homepage, the search engine, and the toolbar might inevitably contribute to system bugs that could be abused by viruses and other threats. This is also one of the key explanations why experts warn against permitting programs such as Drop Extension to run on the computer.

The Drop Extension Chrome Virus

As soon as an app like the Drop Extension Chrome virus gets mounted on your browser, it will do everything in its power to grab your attention and make you click on its ads and links. The Drop Extension Chrome virus will also make visible changes to your browser’s search engine, the default homepage and the toolbar’s appearance in an attempt to facilitate the display of more sponsored search results and promotional messages during your web browsing sessions.

Most computer viruses and malicious programs rely on stealth in order to complete their criminal agenda, thus they are typically very difficult to detect. Browser Hijackers, however, aren’t malware and they don’t try to hide. 

Fortunately, none of these changes I supposed to damage your computer or its files. The purpose of browser hijackers like Drop Extension, Cog ExtensionMe.fo is to encourage your engagement with the paid commercial materials that get displayed on your screen. This is because each click or site visit typically generates pay-per-click and pay-per-view profits for the hijacker’s developers. In the long run, however, putting up with the sponsored advertisements and the constant page-redirects may become very daunting.

The biggest issue here, though, isn’t the irritation and the browsing disturbance, but the fact that the advertising materials that get promoted on your screen may not always be trustworthy. Yes, an app like Drop Extension alone may not be interested to damage your computer, but the same cannot be said about its random ads and web links. It is perfectly possible that the pop-ups, banners and sponsored pages that get promoted through this app may get compromised by computer criminals, hackers and scammers who will comfortably host different viruses, Trojans and Ransomware inside the pages the hijacker may redirect you to.

Thus, the best option to avoid an accidental encounter with sketchy online advertisements and questionable websites is the uninstallation of the browser hijacker and its ad-generating components.
