Answer 1

thanks. spyware scan was clean.
how do i make sure itunes is allowed through antivirus? also,regarding the files to be deleted, where are they located on PC?
The first thing I'd suggest is to get a good
antispyware checker and give it a go at your system.
Some recent spyware has been reported by other users
to shut down iTunes or prevent it from launching.
From user reports, Ewido seems to be the best at
catching it. You can download a free version of Ewido
here.
If that doesn't cure the problem, make sure that any
antivirus/antispyware application you have is set to
allow iTunes to operate. Some antivirus/antispyware
has been known to shut down iTunes. An upgrade to
iTunes or to the utility may have triggered the
problem.
If that still doesn't help, take a look at iTunes for Windows: Troubleshooting unexpected
quits, freezes, or launch failures
If that still doesn't work, try deleting the iTunes
preference files:
C:\Documents and Settings\<username>\Application
Data\Apple Computer\iTunes\iTunes.pref
and
C:\Documents and Settings\<username>\Local
Data\Application Data\Apple
Computer\iTunes\iTunes.pref
You might have to turn on "show hidden files" to find
them. (Right click "my computer", select open, select
Tools menu -> Folder Options. Select View tab, "show
hidden files" radio button is in the center scrolling
panel.) Delete them or if you want to be able to put
them back if it doesn't help, drag them to some other
location. This will force iTunes to run the setup
assistant the next time you launch iTunes. Note that
you'll have to go back and set any preferences you've
changed from the default.
If that still doesn't work, try this:
