Hi,

you can delete the history. It is described on our help page (FAQ)

  • From the main menu, select History.
  • Hover over any entry and click the X that appears on the right.
  • To delete all browsing history, including cookies and more, click the Clear Browsing Data… button on the top-right of the page.

What language of the browser you are using? The situation on the screenshot is not right. The window is broken and texts and controls are missing.

Please also specify browser version (about page)

Thank you

I am using in English and I don’t know which version it was because I saved my computer and I’m using another one currently.
Is there anyway to reinstall avast safebrowser without having to reinstall the whole antivirus?
thanks
