avast free scan results

My system; dual core pentium running at 2.8 gig, 2 gig ram, winxp pro, sp3, firewall Comodo free 5.12.256249

In the scan results there appear some code #s, what do they mean? And how can a file be offline and be found by Avast! and windows explorer?

located in temp folder…so they may be gone?..
anyway, clean your temp folders and they should be gone… http://www.geekstogo.com/forum/files/file/187-tfc-temp-file-cleaner-by-oldtimer/
