Smash Browser adware in detail

Smash Browser adware is based on the Chromium technology platform. It can display banner ads, full-screen advertisements, pop ups, videos, or other varieties of online advertising. Maybe you approve the idea that the ads or pop-ups are just a small problem. But these unwanted advertisements eat computer resources and slow down your web-browser performance.

VirusTotal flagged Smash Browser setup.exe as trojan:

Smash Browser uses its own website (smashbrowser.com) as a search engine. This means that users who use it as a web browser are forced to visit smashbrowser.com each time they search in the Internet, open a new window or tab. And since this website is not a real search provider and does not have the ability to find the information users need, it redirects the user’s web browser to Google, Bing or Yahoo search engine. The devs behind Smash Browser are most probably doing this to generate advertisement money from the ads shown in the search results.

VirusTotal flagged smashbrowser.com as malicious:

Another reason why it is necessary to remove Smash Browser is that it is able to monitor and report on your activity and provide information to a third party. It can install a component (spyware) that enables its creators to track which web pages you visit, what products you look at upon those pages. They are then choose the type of ads they show you. So, if you have adware installed on your personal computer, there is a good chance that you have another that collects and shares your sensitive information with third parties without your consent.

Attackers often use adware to redirect users to malicious and scam websites. Below are some examples of such sites:

To summarize, the adware can lead to malware infection and financial losses. It can seriously affect your privacy, your computer’s performance and security.
