For years my XP home OS has always had about 120,000 files. I installed AdAware 2007 and each time I run it, it finds the usual 8-15 pieces of ad ware that I remove. However, it reports that it has scanned approximately 450K of files. I doubt this report as the sys runs the same as it always has. Any thoughts? Do I have a bacterial culture growing in front of my eyes? DRB
