possible keylogger, malware, I DONT KNOW! Something up.

I have already posted in the Vista section as some problems have been occuring from day one... recently some security issues

I use AVG and Spybot S&D, and just recently AVG detected Windows\System32\ntoskrnl.exe as "change". It doesn't really give any other info, and just before that I had put a trojan in the virus vault (which was most likely d/l from p2p BOO).
I had a problem with facebook and am really worried about a keylogger whatnot...
Nothing has been detected in AVG except Windows\System32\drivers\etc\hosts.exe which i located and (somehow) deleted and then emptied the recycle bin, but has alas reappeared as "change" in avg.

THUS, due to this I (like an idiot) installed a stupid registry cleaner and now am having Spybot S&D tell me it detected an important registry change "C\Program Files\Common Files\InstallShield\UpdateService\ISUSPM.exe" -scheduler
I have no idea what this means and I'm afraid I've trashed my registry, which I never should have touched considering my skill level. Is there a way to undo this, even though I've already uninstalled the cleaner app?

Also I have checked [most of the] processes in Task Manager and they seem to be okay as far as location, etc...

Here is the HJT log:
