MyPCBackup is a rouge that claims it will back up the user's data, and files, in the case that the computer is stolen or if the computer is destroyed by malware. It is usually installed by installing other malicious programs.
It attempts to steal the user's personal information by saying that a virus is detected. Then it will constantly show pop-ups saying
Your computer is not backed up. Back it up now.
If the user would manage to uninstall it, they would constantly receive mails from bots, asking if the user wants their backed-up files to be deleted, these emails can be stopped if the user blacklists the MyPCBackup email.
