Windows XP home edition problems with unknown softwares

[Guest]

Hi,

Currently, I found some strange files in my windows folder of my computer,
they are:

1. C:\windows/Prefetch/SVCHOST.EXE-2D5FBD18.pf
2. C:\windows/system32/wbem/Repository/FS/index.btr.
3. C:\windows/system32/wbem/Repository/FS/index.map.
4. C:\windows/system32/wbem/Repository/FS/objects.data.
5. C:\windows/system32/wbem/Repository/FS/objects.map.

I checked with latest Norton Antivirus software with my computer, but found
nothing. However, when I doing some live update, Norton Personal fire wall
told me that the fourth path obtructing the process for some unknown reason.
So, I triied to delete the 2nd to 5th one by normal, safe and MSDOS modes,
but I couldn't succeed. I also checked these 4 files with Microsoft web site
for file formats and couldn't found anything even with suggested web sites.
So I think these are not the software from Microsoft and its
suppliers/alliances. For the 1st one, I found it strange and it is connected
when I am on the web but without any company name of this file in XP. So I
don't know is it a virus file. If someone who knows about these files and
its functions, please let me know.

I think these files cause my computer work improperly, sometimes, it
couldn't open the web sites that I can get into it in other computers;
sometimes, I couldn't send E-mails as I do on other computers and other
strange things happens, like files move itself, computer function improperly
and so on, there are a lot of problems.

pf files are Prefetch files.

[[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.]]

No pf files will have the info that you would find checking Properties for
an exe file.

This explains a little about Prefetch...

1. C:/windows/Prefetch/SVCHOST.EXE-2D5FBD18.pf

These are normal.

2. C:/windows/system32/wbem/Repository/FS/index.btr.
3. C:/windows/system32/wbem/Repository/FS/index.map.
4. C:/windows/system32/wbem/Repository/FS/objects.data.
5. C:/windows/system32/wbem/Repository/FS/objects.map.

However there can be problems if Windows Management Instrumentation (WMI) is
corrupted.

Windows XP reports that Windows Management Instrumentation (WMI) might be
corrupted?
