XP slow boot, slow progam loading, slow internet. PLS help

The other day despite my better judgment I downloaded a keygen I know should not have and it went ahead and infected my computer with a virus (or 2, or 50).
I've run pretty much everything I can, followed a malware disinfection guide from majorgeeks.com and am now turning to you guys for help.

I believe I've removed most of the problem virus'/malware/spyware. However it's left my system a little sluggish. Meaning, instead of a 1 minute windows boot its about 3. Programs take closer to 20-30 seconds instead of 2-5 seconds and web page loading is ridiculously slow, meaning more than a minute.

I am running:
XP pro sp2
P4 prescott 2.6Ghz
2 gb Ultra PC6400 DDR
Asus P4P800 se mobo
Western Digital 80 gb 7200rpm
G-Force FX6600

I have ran Hijackthis and attached the log.

P.S. Programs and web pages seem to run at regular speed once they have loaded. - even the attachment window is took a while

to make sure your pc is clean get mcafee rootkit detective and let it clean up

root kit report

i've attached the rootkit report. i dont want to get rid of anything important.

sorry to identify all of this will take a while. I would let rootkit do its job. it does usually not destroy things which do no harm.
