Full System Scan says it is working, but doesn't progress beyond 29-30 thousand files. Then it gets stuck on one file. The "alive" light scan at the window top is still active, but it remains on that file, with the Pause or Stop buttons having no effect.
This happens on the same file. I tried deleting this file, but Norton Internet Security just finds another file to hang on.
I am running Windows 7 in 64-bit mode with 8 GB memory. Both OS and Norton are up to date.
