Search function problem

Ok I tried restoring to an earlier date and that didn't help. I updated my virus protection and did a scan for that. The only thing I have done that I can think of is intstall a microstudio demo. The only other thing I notice is that I have a file on my desktop that I have no clue where it came from and has files in it that I don't know what they are. They have the file extension .IRX
And there are some .ALL files
I'm not sure what to think at this point. At least everything else works fine, but I can't believe how much I miss it!

Thanks for the idea's. If you have anymore I'll take them! And I'll let you know if I fugure it out.
