Privilege escalation and file deletion via symlink race

Race condition in QuickClean in McAfee Total Protection for Windows before 16.0.43 allows local users to delete arbitrary files. QuickClean checks a path and later deletes it, while a symbolic-link substitution during the race redirects the privileged deletion to a different file. A low-privileged local account and a successful race are required; the resulting deletion can remove sensitive files and cause an unspecified denial-of-service condition.
