Eu não sei o que é, eu não vou clicar nele e você não pode clicar com o botão direito do mouse no link. Como posso descobrir o que é, e se é malware Como posso identificá-lo como tal?
I don't know what is, I won't click it and you can't right-click the link. How can I figure out what it is, and if it is malware how can I identify it as such?
Are you using the browser extension "Click & Clean"? This looks like one of their messages to me. Click & Clean offers you to clear your browsing history (cookies, history of visited sites etc.). You can do that automatically, when you exit the browser, and/or by clicking on a button. This message basically tells you "Hey, you haven't cleaned your browsing history in a while, maybe you want to look into doing it now".
You can upload and scan any file to VirusTotal
You can also do a site search for executable files you might be leary of as well.
