Just for a heads up. After several posts here comparing the pros/cons
of maintaining my computer vs. formatting and installing XP, I finally
made a move. I tried every imaginable tool to keep my pc clean. I use,
faithfully, a good AV, firewall, several spyware apps (on board and
online), CC cleaner etc., etc. I am diligent with program installation
and proper removal and updating drivers. I can't see what I do wrong,
yet my computer performance deteriorated with time. It ran like crap!
Finally I formatted/installed XP, drivers, programs and apps and she
runs like a charm once again. I don't know.
Not enough information, Ed.
Not all antivirus programs are helpful. Some are resource hogs and when
out of the box, will scan your entire hard drive every time you boot up
your PC. For most people, the built-in Windows firewall is sufficient.
Also, some people unknowingly run their third-party firewall along with
the Windows firewall -- a no no!
You haven't told us which particular programs you run. Without that
information and without knowing how the programs are configured (for
instance, it's also problematic to have two anti-spyware programs
running at the same time), it's hard to know what's going on.
You also didn't tell us the make/model of your PC along with its specs.
Perhaps you don't have enough RAM for the combination of programs your
run. We don't know how much free space you had on your hard drive. You
didn't post any error messages or provide information such as if any
particular process is consuming a lot of RAM and/or CPU cycles (info
gleaned from Task Manager).
You never told us if you ever configured a clean boot to see if the
sluggishness went away.
You never told us what impact upgrading to SP3 had on your PC.
Running anti-malware programs does not guarantee you will never be
infected by malware. Some programs are better than others at detecting
malware (currently, Malwarebytes' Anti-Malware is among the leaders).
Sometimes, a scan needs to be performed in Safe Mode. Sometimes, a boot
disk is even necessary.
The bottom line: It isn't a mystery at all why your PC "ran like crap."
All that is needed is facts, and by using the scientific method, the
reason will eventually reveal itself.
In the event you don't practice the safest "hex" possible, these links

Regarding sluggishness in general, here are its usual causes:
1. Malicious software (malware)
2. Certain programs that are designed to combat malware (e.g., Norton
and McAfee). Ironically, they can slow things down because they simply
use way too many resources. Sometime they cause conflicts with other
programs. And their default mode is to scan your entire hard drive each
time you boot up.
3. Too many of *certain types* of programs always running in the
background -- with or without your knowledge.
Use these sites to determine what these programs are and to learn how to
configure them not to always run at startup:

Sometimes it is recommended to use msconfig to configure the programs to
not run at startup. A better, more thorough program is Autoruns:

4. Not enough RAM, which causes the PC to overly rely on the pagefile. A
quick way to determine if this is happening is to open Task Manager
(Ctrl+Alt+Del) and click the Performance tab. Then note the three values
under Commit Charge (K): in the lower left-hand corner: Total, Limit,
and Peak.
The Total figure represents the amount of memory you are using at that
very moment. The Peak figure represents the highest amount of memory you
used since last bootup. If both these figures are below the value of
Physical Memory (K) Total, then you probably have plenty of RAM.
Otherwise, you may want to explore this further by running Page File
Monitor for Windows XP:

5. You might also want to check that your hard drive's access mode
didn't change from DMA to PIO:
