If you're familure enough...you can boot into dos (I've always used a 98 boot disk, just 'cause it's around, but many ways should work!) And you can navigate to where the files are... such as
C:
cd documents and settings
cd username
cd my documents
dir *.* /p -- /p lists one page at a time, if you have a lot of files there
and find the troublesome files, then
del troublefiles
It's probably likely (as cook was hinting at) that the files aren't located there, being that it's not really possible to hide themselves any better if the virus is truely gone.
Also, note this! Two possabilities:
1. check your recycle bin/empty it.
2. check ad-aware's quarentine, make sure it's not holding the files. if it is, make sure to delete them...to regain your lost space.
