Canary6,
Thanks for posting that, here is my opinion, when I say 'delete' below you have the option to copy off to another disk or move to another folder OR delete it. The choice is yours (I'd delete them) , but if they are left in place they will be using up resources and could be causing your issues. The items that load at the system level are troubling. There is a lot of potential for things to go wrong when something has all that power inside the system.
You will also want to have a sound backup before you modify the system.
Find these in: /Library/Extensions/
Kernel Extensions:
com.symantec.kext.internetSecurity (5.3f6)
com.symantec.kext.pf (5.6f22)
com.symantec.kext.ips (3.9f13)
com.symantec.kext.fw (5.3f12)
com.symantec.kext.SymAPComm (12.6f28)
These all load into the kernel, so this software better be the most current version. The kernel is the core of the operating system, it is better to avoid third parties doing anything at that level if.
It's pretty clear that Mavericks is in it's 'teething phase', so adding in extra code won't help matters.
Personally I think there is little reason for running Symantec's tools on a Mac so turn off as much as possible if you must run it.

All of the [failed] jobs are all worrying. Failed means crashed, or doing something it isn't supposed to do.
The first two types run at the system level, so it it very important to remove them or make sure they are up to date. The ones inside your home are all running at the same level as your user. They can't wreck the system, but they can use up RAM & CPU and make other tasks slower. You probably only need one Adobe updater job (com.adobe.ARM.[...].plist).
The simplest thing to do is remove all of the failed jobs & reboot. They are .plist files (property lists).
Some jobs may come back, especially Symantec's because they will try to "keep your system secure" but that also means "make your system work harder".
You may have to follow Symantec's uninstall instructions to remove it completely.
Clean up any you don't need.
Run etrecheck again to see what jobs return.
Find these in: System Preferences > Users & groups > select your account > Login items tab.
User Login Items:
Check these apps are all up to date, remove them if you want to see if the Mac will login any quicker. If you miss them re-add them one by one, so you can see if it has a noticable effect.
Find these in: /Library/PreferencePanes/ or ~/Library/PreferencePanes/
3rd Party Preference Panes:
Check these are all up to date or remove them.
Find these in: /Library/Internet Plug-Ins/ or ~/Library/Internet Plug-Ins/
Internet Plug-ins:
You have several copies of old Flash player, Adobe reader & Java Applet plugins.
Delete them or update them.
Java is so insecure it's not clever having it around inside the browser at all. Also disable Java in Safari's settings if it is on - it defeats the point of all that Symantec 'security' software. Java apps are OK if you need them - just avoid it in the browser at all costs.
Don't forget to reboot once the changes have been made.
I hope that helps, ask if you have questions, good luck.
