Very slow computer and a trojan or 2

Apparently you did not read this link in the Read and Run First Instructions:
Uninstall Malware via Add/Remove Programs. Had you looked at that you would have found the main cause of your problems:
Messenger Plus! Live --> Uninstall this!!

Now, I will chastise you once more. It is a very bad idea to allow all users to have Admin. privileges!! Once malware gets on your system via an Admin account, it has free reign to infect all your user profiles as well as access to all files and folders.

Code:

Users on this computer:
Is Admin? | Username
------------------
   Yes    | Administrator
          | ASPNET
   Yes    | Cally
   Yes    | Greg
          | Guest
          | HelpAssistant (Disabled)
   Yes    | Jack
          | MCX1
          | MCX2
   Yes    | Miriam
          | SUPPORT_388945a0 (Disabled)

I am not seeing much in your logs. You will have to tell me what was reported as trojans and what reported them ( I need the exact path to the file).

Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator). This is really HijackThis (select Do a system scan only) and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:

After clicking Fix, exit HJT.

Now Copy the bold text below to notepad. Save it as fixME.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.

Make sure that you tell me if you receive a success message about adding the above
to the registry. If you do not get a success message, it definitely did not work.

I have no idea what this is, so unless you know, lets rename it by right clicking the file and rename it to .old:
C:\WINDOWS\zwcm.bin --> so it is now C:\WINDOWS\zwcm.bin.old
Let me know if something stops working correctly. But I am fairly sure it needs to go.

You need to start using a startup manager. You have a lot of items running at startup that do not need to run.
You may wish to use one of these:

Startup Manager

Startup_CPL

Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator).

Then attach the below logs:

* C:\MGlogs.zip

Make sure you tell me how things are working now!

 

Yes you can use safe mode to do the fixes. You still need to tell me what the reported trojans were and the path to them.

Didn't see your edits.

 

The MBAM log that you attached found two items and removed them. After doing my fix, tell me what problems you are having.

 

I am not seeing any malware on your system. You are still allowing all users to have Admin. privileges, so I suggest you try to log into each account, see if you have the same problem on each, and to be sure, run both SAS and MBAM on each account. Attach any logs that show infections ( making sure that you identify which account they are).

 

I would suggest that you try using a start up manager:

You may wish to use one of these:

Startup Manager

Startup_CPL

If you are not having any other malware problems, it is time to do our final steps:

1. We recommend you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no real-time protection. They are useful as backup scanners.They do not use any significant amount of resources ( except a little disk space ) until you run a scan.
2. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
   
   • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
   • "%userprofile%\Desktop\combofix" /uninstall
     
     • Notes: The space between the combofix" and the /u, it must be there.
     • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
4. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
5. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
6. Go to add/remove programs and uninstall HijackThis.
7. Goto the C:\MGtools folder and find the MGclean.bat file. Double click on this file to run this cleanup program that will remove files and folders related to MGtools and some other items from our cleaning procedures.
8. If you are running Vista, Windows XP or Windows ME, do the below:
   
   • Refer to the cleaning procedures in step 3 the READ ME for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
   • Then reboot and Enable System Restore ato create a new clean Restore Point.
9. After doing the above, you should work thru the below link:
