[[When you open System Configuration Utility [MSCONFIG], Registry Editor or
Task Manager, they flash for a second and quit. This symptom is caused by
Viruses.]]
Task Manager, MSCONFIG, or REGEDIT disappear while opening

HELPCTR.EXE is the Microsoft Help and Support Center. As in Start | Help
and Support
The PF file is a prefetch file.
[[Prefetch files are essentially a resource list. Any time a program is
executed, Windows XP will attempt to find a pre-existing prefetch file, and
if it's available, it will use it to make the application load up faster.
The file will also be updated after it is accessed, so that the more an
application is used, the bigger the drop in loading time (to a point). If
the application doesn't already have an associated prefetch file, Windows XP
will create one. Those files are stored in the \%windir%\prefetch directory.
One important note is that the process depends on the Task Scheduler
service. If the Task Scheduler service isn't running, the prefetch mechanism
isn't used and the files won't be read or updated.]]
