After startup, the processes mstask.exe, system.exe, hql.exe, nvmqi.exe and faxshellm.exe initially take 99% CPU time, after a few minutes faxshellm.exe alone takes 99% and keeps doing so until stopped. About nvmqi.exe and faxshellm.exe there seems to be no info on the web. Is malware involved?
Thanks for your willingness to help. PC: old Compaq; Windows: 2000. Protective software: formerly service provider's own (Telenet), recently ESET NOD32. File faxshellm.exe is a hidden protected operating systems file in C:\WINNT\System32. Scan by NOD32 yields for faxshellm.exe a message: "error - could not open file". Attempt at manual removal: "access denied - file may be in use" (although not in task manager's running processes list).
