already have taskmgr.exe and taskman.exe but in system32 folder, and also scanned both: taskman.exe in system32 folder is the same file as the above one and it´s infected too, while taskmgr.exe has no infections at all
Status: Scan finished. 1 out of 20 scanners reported malware.

I tried to remove the file, but reappears seconds after. How can I delete it?
