Regarding the freeze problem only (I think I have bothered more than
enough people on this list already with rants about Tiger's
instabilities): I can think of three possible causes, other than bugs:
- Spotlight updating its databases in the background.
- Some network activity failing silently in the background (through
all versions of OS X, I have experienced freezes or slowdowns with
some network tasks in the Finder, especially with FTP -- for example
when you click on an FTP link in Safari or Mail, and the Finder
cannot connect to the FTP server).
- Antivirus software like ClamXav scanning directories in the
background (see below).
But yes, I am also experiencing once a day, say, freezing
applications with no definite causes. Usually terminate the process
with Cmd-Alt-Esc. Happens more often on my 400 MHz/384 MB RAM/30 GB
HD PowerMac than on my 1 GHz/1 GB RAM/60 GB HD PowerBook, which makes
me think it must be connected with either of slow processor/low
memory/small disk space.

With Virex incompatible with Tiger, and now than ClamXav <http://
www.clamxav.com/> has reached version 1 and is more compatible with
Tiger (it doesn't fuss with the NetInfo clamav user pre-installed by
Tiger), I am using ClamXav for antivirus scanning. It can scan
folders/drives on demand, and includes a Sentry function for scanning
specified directories automatically. I have set the Sentry to scan
the Desktop (my download directory) and the various Inboxes and Junk
mailboxes of my Mail accounts.
That said, as with any virus scanner I have tried so far, this Sentry
function ends up invariably at some point with unexpected slowdowns
nay crashes, and I will probably, as always, disactivate automatic
scanning and only leave scanning on demand (for email attachments,
typically, before forwarding messages to Windows users).
