okay here is an exact description

Okay, if I go to run and type in MSconfig or MSconfig.exe
it pops up w/a message saying windows can't open that
file. That for window to open it it needs to know what
program created it. If i double click on any icon in my
start up menu it won't let me in. says it doesn't know
that file...same as what i said before just different
file. Ummm...lets see...i can't go into control panel, i
can't run my adaware/spybot/etc.(yes i did do those
already and it didn't get rid of this brower hijacker so
i had to do it manually, but i don't know enuff about it
apparently and I messed it up). I can't run a program
that has .exe
I deleted all of the .exe files in my registry. Yes, I am
dumb/stupid whatever you wanna call me. I messed up.
Would anyone please help to fix my mistake??

My best guess is you need to do a repair install - you'll need your XP
install CD and Product Key. This is a link to a MS article describing how
to do a repair install.

You could also call tech support where you got your computer.

You may need the EXE File Association Fix (Restore default association for
