Three changes to Google's Chrome browser for Windows are intended to reduce the impact of browser-based malware.
The first has already helped millions of users recover from unwanted changes to settings, according to Chrome Cleanup product manager Philippe Rivard.
It works by watching for unauthorised changes to user settings, such the search engine. When such changes are detected, Chrome offers to restore the setting and disable extensions that can modify settings.
"Using the Internet should always be a smooth and safe experience for everyone," said Eset chief technology officer Juraj Malcho.
"For three decades, Eset has developed a number of security solutions that allow users to safely enjoy their technology and to mitigate a variety of cyber threats. Chrome Cleanup addresses unwanted software that can negatively influence a users' experience on the Internet."
Finally, Chrome Cleanup has been completely redesigned with a new, simpler user interface, making it easier to see what will be removed. In addition to removing offending software, Chrome Cleanup changes settings back to their default values.
Chrome Cleanup is specific to the Windows version of Chrome. Users of the Mac or Linux versions are responsible for detecting and removing any unwanted additions to Chrome.
