If a process named boot.exe is running on your computer, you may have been infected with a strain of the Elem Trojan.
boot.exe is considered to be a security risk, not only because antivirus programs flag Elem Trojan as a trojan, but also because other sites consider it a Trojan as well.
Elem Trojan is likely a Trojan and as such, presents a serious vulnerability which should be fixed immediately! Delaying the removal of boot.exe may cause serious harm to your system and will likely cause a number of problems, loss of data, loss of control or leaking private information.
Are you running a dual boot with linux?
