In recent days Browsing the internet without any security is very harmful to our systems and we can easily exploit our privacy so browser security is important so what is Browser security. Browser security is the application of Internet security to web browsers in order to protect networked data and computer systems from breaches of privacy or malware. Security exploits of browsers often use JavaScript sometimes with cross-site scripting (XSS) sometimes with a secondary payload using Adobe Flash. Security exploits can also take advantage of vulnerabilities that are commonly exploited in all browsers. Recently Google added antivirus features for chrome these three security parameters allow users to browse safely.
Three basic antivirus features for chrome
Unwanted software impacts the browsing experience of millions of web users every day. Effects of this harmful software are often quite subtle—search results are modified to redirect users to other pages or additional ads are injected in the pages that users visit. But in some cases, the changes are so severe that they can make the web unusable—people are redirected to unwanted sites full of ads, and it can be next to impossible to navigate away from these pages. Chrome already has tools to help people avoid unwanted software. For example, Safe Browsing prevents many infections from taking place by warning millions of users. But sometimes harmful software slips through. Recently, we rolled out three changes to help Chrome for Windows users recover from unwanted software infections.
Hijacked settings detection
 Chrome more useful—like by customizing tab management. But some extensions may change your settings without you even realizing it. Now, when Chrome detects that user settings have been changed without your consent, it will offer to restore the modified settings. In the past month, this antivirus features for chrome has helped millions of people recover from unwanted settings. You can also reset your profile settings at any time by visiting chrome://settings/resetProfileSettings. 
A simpler Chrome Cleanup
 Sometimes when you download software or other content, it might bundle unwanted software as part of the installation process without you knowing. That’s why on Chrome for Windows, the Chrome Cleanup feature alerts people when it detects unwanted software and offers a quick way to remove the software and return Chrome to its default settings. We’ve recently completed a full redesign of Chrome Cleanup. The new interface is simpler and makes it easier to see what software will be removed. 
A more powerful Cleanup engine
Microsoft, they upgraded the technology we use in Chrome Cleanup to detect and remove unwanted software. We worked with IT Security company ESET to combine their detection engine with Chrome’s sandbox technology. We can now detect and remove more unwanted software than ever before, meaning more people can benefit from Chrome Cleanup. Note this new sandboxed engine is not a general-purpose antivirus—it only removes software that doesn’t comply with our unwanted software policy. The biggest addition is a new option to detect if settings like the default search engine have been hijacked by a rogue extension, and automatically offer to set things back to normal. Google Chrome users on Windows will be able to enjoy a little more peace of mind Additionally, the built-in Chrome Cleanup tool has been redesigned. The revamped tool is now simpler to use: it automatically removes harmful software with the press of a button and is more powerful, thanks to a partnership with IT security firm ESET. Google is quick to note that Chrome Cleanup isn’t a catch-all antivirus solution, though; it will only remove extensions that violate Google’s Unwanted software policy, so you’ll still want to make sure that you’ve got some sort of regular antivirus software set. Hopefully, the new changes will mean that Google Chrome users on Windows will be able to enjoy a little more peace of mind going forward. Or at the very least, cut down on frantic tech support calls from less tech-savvy family members and friends wondering why Google search isn’t working anymore.
