Invalid in Reigistry entry

[shafi007]

Hi,

I am using System Mechanic (

http://www.iolo.com),

which will clean the registry if there is invalid entries found. I often use this to delete the invalid entries in my registry.
Now in recnet scanning I found the following three invalid entries in my registry, If I remove this also, it is remain there if I rescan, these are the entries I get

HKEY_CLASSES_ROOT: VBEFile\shellex\PropertySheetHandlers
HKEY_CLASSES_ROOT: JSEFile\shellex\PropertySheetHandlers
HKEY_CLASSES_ROOT: WSFFile\shellex\PropertySheetHandlers

I am using PIII, 256MB RAM, with Windows 98 SE

I suspect it may be by a trojan or virus, I kindly reauest you the professionals here to help me.

Thank you

Shafi
