Not overly unusual, but happening less and less as OS X matures. First 
thing I'd do is run Disk Utility and have it repair permissions and do a 
disk check to be sure the disk is ok. Once both of those are complete 
(and report that all is ok), I'd get the OS up to date. 10.4 is up to 
10.4.7, so run Software Update and get the latest updates.

What was happening? Alas, you are on cable service, which means you 
should expect problems from time to time and that you need to reboot your 
cable modem from time to time.

It is 100% impossible to know if ANY computer has spyware based on a ping 
test. If he did a port scan, maybe he could infer spyware based on some 
open ports... but then, you ARE running behind a firewall or NAT router 
correct? (there should be some kind of router device between you and your 
cable modem that is giving you a non live IP address, ie: an address 
likely in the 192.168.x.x range)

Currently there is no known email exploits on the Mac. Were you sent 
strange Mac compatible attachments that you promptly ran? Unless you did 
that, then your problems are almost certainly not from email you received.

Of course, just because you've never had spam in the past, doesn't mean 
you didn't get it now. If you haven't had it before, it is just a matter 
of time before you do get it. Spam is just something that everyone has to 
accept is a part of using email.

if you REALLY want to be sure nothing unusual is running on your Mac, 
open a terminal window, and type the following:

ps -A >running

be sure to make that a capital A. After you do that, if you check your 
user home folder (the same folder that contains things like your 
Documents folder, Movies folder, Music, Sites... all those), you should 
now have a file called "running" in there. Email me that file. That file 
will contain a list of all processes running on the Mac. If you email me 
that list, I can look it over and tell you if anything is running that 
shouldn't be.

But I'm pretty confident as is, that your issues are not spyware or any 
other kind of malware related. I suspect you have nothing more than some 
permissions errors, possibly minor disk corruption, and are out of date 
on bug fixes. I just think it is a coincidence of timing that you got 
spam and your cable modem crapped out and needed to be rebooted.
