unsure of malware

Hey, been here several times before, always very helpful. I'm on my secondary computer right now which is 7+ years old and I was hoping to fix it up. It's slow because of its age and limited space but recently programs have been freezing and I was wondering if I posted a HJT log whether any of you guys could point out some problems that have gone undetected or undiagnosed. Lately I've noticed weird things running in the task manager. Any help would be great.

Hello.
The log looks fine, but I need to ask, what do you plan for this machine? there is something we can remove, and update. But, looking at the log right now, this machine is only running XP and no service pack.

a) this is very dangerous
b) to make it worse, there's no AV on here.

As there is limited space anyhow, is it worth the time to install newest software on here?

I use this computer very seldomly and will probably get rid of it sooner than later. I was thinking that if there was something blatantly wrong + correctable, I could spend a little time and fix it, but no, it isn't worth any major updates or installations. I think in the meantime I will download Avast! or something just in case I can do a little minor cleanup. Thanks again for the quick help.
