How to remove Violent_shark extension from web browsers
Written by Tomas Meskauskas on (updated)
What kind of extension is Violent_shark?
Our analysis of Violent_shark has shown that it is an unwanted extension distributed through a malicious installer (multiple security vendors flag this installer as malicious). Violent_shark has no clear functionality, but it is very likely that it could expose users to security and privacy issues.
Violent_shark in detail
We found that Violent_shark is not always added to Chrome browsers like any regular extension. During our examination, we discovered that Violent_shark can be loaded in Chrome windows opened by malicious components, while the extension may not be present when a user opens the browser (or a new window).
Our other finding is that Violent_shark can manage downloads, apps, extensions, and themes. It may be capable of removing, disabling, and adding extensions to Chrome browsers. These modifications may lead to the injection of malicious components. Also, this extension can change browsing history on all signed-in devices, possibly to hide its traces.
Furthermore, Violent_shark may change the settings of a web browser, such as the homepage, search engine, and (or) new tab page. These changes can cause redirects to unreliable pages designed to promote various scams, shady apps, and other unreliable content. Also, it may be difficult for users to revert to their preferred configurations after the changes made by Violent_shark.
Moreover, Violent_shark can track users’ online activities without their consent. This data collection can include browsing history, search queries, and even login credentials, credit card details, or other sensitive information. This data might be sold to third parties or misused for malicious purposes like identity theft.
Another possible issue that Violent_shark may cause is that it may generate annoying and misleading advertisements. These ads may promote technical support scams, fake giveaways, lotteries, other schemes, and potentially malicious software. Thus, users may be tricked into transferring money to scammers, downloading harmful software, disclosing sensitive information, etc.
Overall, Violent_shark is not a reliable extension that should be removed from affected browsers as soon as possible to avoid potential risks.

How did unwanted software install on my computer?
Unwanted apps like Violent_shark are often distributed through deceptive websites, P2P networks, unofficial app stores, third-party downloaders, and similar channels. They may also spread via misleading ads, pop-ups, and notifications from shady web pages. Users add/or install such apps by interacting with dubious content or downloads.
Another common method is bundling, where unwanted apps are included as additional offers in software installers. If users do not adjust "Advanced", "Custom", or similar installation settings or leave default checkboxes selected, these extra apps can be installed without the user's full awareness.
How to avoid installation of unwanted applications?
Only download apps from official websites or trusted app stores, and avoid files and programs from unofficial sites, third-party downloaders, P2P networks, etc. During installation, choose "Custom", "Advanced", or other options to deselect any unwanted offers (apps, extensions, toolbars, etc.). Be cautious with ads, pop-ups, or deals on untrustworthy websites.
Do not permit suspicious sites to send you notifications. Use a reliable antivirus program and regularly update your operating system and software. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
