I saw your post in the other forum and was going to reply there, but when I tracked back I found this one, so rather than ask you to repeat everything you said, I thought I would intrude here.
I see you have two computers, a Win 7 system and a Windows XP system. It seems the Win 7 computer is working reasonably well, so I won't be mentioning that as it will just confuse me,
Your HJT log is for the Windows XP computer. You will probably know by now that these forums do not generally analyse HJT logs. They are complicated and time consuming analyses, and there are other forum sites dedicated to doing these. We are not one of those, but nevertheless they are often very useful in targeting particular problems.
In your case you mention in your first post in this discussion that this XP system is slow, and you suspect conflicting programs. I see you tried to post elsewhere before this, but being honest here I have not read your other discussions. I have come here fresh.
XP is an older OS of course. Mine still works well, I still have and use my XP system even though I now generally use my newer Win 7 computer. But I know that, as the OS gets older, it will start to struggle with today's newer software. Not only because the OS is ageing, but also because, generally, these XP computer systems have outdated hardware. The processors and motherboards are slower, RAM, (memory), is often smaller, graphics cards are less powerful, and hard drive connections are often the slower IDE type cables, or older SATA Controllers. That doesn't mean that it will stop working; it just means that we have to be more circumspect with what we install and what we use on these systems.
So, although we still want to protect them from malware and hacking if they are used on the internet, today's anti-malware software taxes the OS more than they did when XP was younger and said software was more suited to XP. That software is now more suited to the higher performing Vista and Win 7 systems. On my own XP system I now keep security software to a minimum to avoid taxing the OS as much as I can. On mine I have a 3rd party firewall which includes anti-virus. This is ZoneAlarm, and it runs in the background all the time. I have no other security software running in the background. However, I still have MBAM, (MalwareBytes Anti-Malware), and SAS, (SUPERAnti-spyware), installed and I run manual scans every so often. They do not run continuously, (in the background).
That works for me and I have no problems, but of course I take other precautions like watching which sites I visit, and being careful which emails I open. I am not saying that you must use the same utilities as me. All the recognised ones work well.
So, when I looked at your HJT log, what I could see immediately for what seems like security programs are the following;
AntiVir Desktop &
I also saw mention elsewhere of Spybot Search & Destroy and SpywareBlaster. I know you have now uninstalled Spybot.
I don't know much about all of the items in the list, so I have to ask?
What is OnlineArmor? Is it a firewall and an anti-virus, or just a firewall?
What is AntiVir? Is it an anti-virus, or a firewall and anti-virus?
Does SUPERAnti-spyware run in the background?
Why are you using Secunia PSI?
The general rule, for all Windows OSes, is this; Only one firewall. Only one Anti-Virus. They must both run in the background and the anti-virus must be kept up to date. If you have one security utility that 'combines' a firewall, an anti-virus, and, (perhaps), an anti-spyware, then you do not need any other.
Do not have any anti-spyware running in the background. By all means have an anti-spyware utility installed, (I have two, MBAM and SAS), but not running all the time. Instead, you can run your anti-spyware once a week or so to update its definitions and then run a manual scan.
Both Spybot and SpywareBlaster were great utilities in years gone by, along with Lavasoft's AdAware. But we find, sadly, nowadays that they often conflict with today's more comprehensive background running anti-virus scanners. In particular, Spybot's TeaTimer Advanced Mode scanning component, and Lavasoft's AdWatch scanning component. You don't have Lavasoft, and you have uninstalled Spybot. Good. Personally I would also uninstall Spywareblaster. It is no longer required. But if you do uninstall it, make sure you remove its inoculations first.
Can you consider all this and decide what you 'really' need on this computer? I believe that what you have may be the conflicting software you feel you have.
The next steps, to be considered later, will be to look at "Startup files", software that loads at startup. These are the 04 entries in the HJT log. I think you have too many, and unwanted;
AGRSMMSG.exe - http://www.neuber.com/taskmanager/process/agrsmmsg.exe.html
DivXUpdate.exe - DivX Player Updater
Java Update\jusched.exe - Java Updater
QTTask.exe - QuickTime Player Updater.
realsched.exe - RealPlayer Updater.
Then we look at BHO's, (Internet Explorer Browser Helper Objects), 02 in the HJT.
But they are for later.
