Problem solved.

I tried CCleaner and installed Avira free successfully.(it used about 80MB disk space)

Thanks for all your comments and suggestions.

I think this thread can be closed now.

If you do not use "Hibernate", go to Windows "Disk Clean" and tell it to delete your "Hibernate" file. It is usually slightly less than your RAM. In your case, you would probably free up about 400 megs of HDD space.

Thanks. I'll try that.
