This website is a convenient way to share FRST.txt, Addition.txt and similar logs with malware removal helpers that occur during malware removal. It makes sure that other people cannot see your logs.
Farbar Recovery Scan Tool does not expose private information except for the username and computer name. However, for some people this is already more than they are willing to expose.
Sites like pastebin.com sometimes refuse to let you upload logs from these tools because depending on the infection they may contain malware commands that these websites deem suspicious.
Logs get deleted automatically after 30 days.
