I've upgraded to the latest version of Norton Protection Centre and I've not found it as satisfactory as the 2007 version. The old version used to clear out almost all my nasty spammity-spam - I had maybe one message every two months. With the 2008 version I get about 10-15 a day. Some of them are marked [SPAM], some not. There doesn't seem to be any way of customising the email scanning facility. The window is pretty useless.
Secondly, when doing a Full System Scan I always seem to get a seize-up after scanning about 5000-odd files (just a few minutes into the the scan). This has happened 3 times now.
I've been getting freezes a lot on the screen in the past few weeks and have found CTRL-ALt-DEL and ESC not to work, and in the end a "cold boot" (switching off, in English) is the only thing that has brought my PC back to me. (Don't know if it is related to Norton - sometimes it has happened just when using Firefox.)
I've had a quick scan of the PC Hell site but there doesn't seem to be anything suggested that I haven't tried.
If anyone can cast any light I'd be most grateful.
