windows in search files displays files that I cant find

Hi Experts,
Thanks for replying.

@A Karelin, Olemo
As you can see on screenshot, when files are in a zip file it get displayed ...zip, for me this looks like certain bug, I also realized that for those unknown files the full path is not displayed, see attached.
where di I get this Index options? (win XP Pro)

@viki2000
My windows updates are up to date, the same with my virus protection, however I will try running that scan program (at the moment its asking for the XP CD and I have to locate it..).
BTW, how do I perform file searches in Win7? in that place type in file or program I don't have the ability to specify file location etc..

Thanks,
Ben

Hi Experts,

I found the culprit, its a backup software that is running somewhere and creates all those files in zip folders.
The reason I didn't accept this answer at first place was due to the fact that the search engine did display some files within zip folders along with their full path, however what I concluded now is that this is only true when the files is under the root folder of the zip file, but when this is embedded deep into folders within the zip, it will only display the folders names without the full path, like in this example (Conversion\mde) which is really under F\MyBackupFolder\WeeklyBackups\Backup1234.Zip..

Thanks very much for your help!!
