Is his other thread with hijackthis log Ried cleared.
My first suspicion would be that this is style XP related.
I have frequently seen cases where messing with windows with this and similar programs have slowed things down. If you want things all frilly and different , they will be slower.
My advice here is to revert to the standard windows classic theme and set the wall paper to none with color windows blue.
Revert any other changes style XP made and uninstall it.
It is hard to figure out what was removed and whether you have disabled some things in the second log.
Initially I see you have this running
C:\Program Files\Common Files\Microsoft Shared\VS7DEBUG\MDM.EXE
As noted running a debugger if you do not need to be doing so will slow your machine.
If you still have it enabled follow the instructions to turn it off.
Go to control panel / system / advanced / startup and recovery / settings
Change save dump file to NONE
I see in your cleanup log from ewido reference to alcohol 120%
Do you by any chance have the "Virtual drive" from alcohol 120% installed/ enabled? It can cause some real issues under certain circumstances. If not actually necessary at this time ( you do not have an irreplaceable image mounted to it that you cannot burn to cd) I suggest disabling / removing it and reboot and see if that helps.
Now that you are cleaned up; I suggest you deal with possible damage to your Norton Internet Security which may have occurred. I have seen cases where when malware is removed, the firewall access rules are corrupted and cause major slowdown.
Step one is to run Live Update manually, select all updates it finds and download. Restart computer (even if it finds none ) and run it again. Repeat until no updates are found.
Then go to the firewall access wizard and run it again. It should be in either start / programs / norton internet security or in the NIS control under options / firewall/ programs
I also would ask if you have used msconfig to disable any programs. Many programs have components elsewhere (such as services entries, winlogon entries, ssodl entries etc) and improper disabling of the startup entry can cause major slow downs as the remaining components keep trying to find their
master startup entry.
