Need help with some malware

I know you said there is a problem with Windows Update but this PC has not been updated in MANY years. It is still running Windows XP SP1. Why wasn't it ever updated?

Note: It also does not have enough memory to properly run Windows XP anyway. The logs show

Code:

Time Zone	Eastern Standard Time	
Total Physical Memory	512.00 MB	
Available Physical Memory	295.41 MB

It need another 1.5 GB.

I'm not too sure all the problems are due to malware, but let's cleanup what I see and go from there.

Uninstall the below software:
Viewpoint Media Player (Remove Only)


Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista or Win 7, 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:


R1 - HKLM\Software\Microsoft\Internet Explorer\Main,CustomizeSearch = res://C:\PROGRA~1\Toolbar\toolbar.dll/sa

O18 - Protocol: tpro - {FF76A5DA-6158-4439-99FF-EDC1B3FE100C} - (no file)


After clicking Fix, exit HJT.


Now Run this Disable/Remove Windows Messenger to remove Windows Messenger. Do not confuse Windows Messenger with MSN Messenger because they are not the same. Windows Messenger is a frequent cause of popups.


Please download OTM by Old Timer and save it to your Desktop.

• Right-click OTM.exe and select Run as administrator to run it.
• Copy the lines from the below codebox to the clipboard by highlighting ALL of them and pressing CTRL + C

  the code box

• Return to OTM, right click in the Paste List of Files/Folders to Move window (under the yellow bar
  ) and choose Paste.
• Now click the large http://forums.majorgeeks.com/chaslang/images/MoveIt!.png button.
• If OTM asks to reboot your computer, allow it to do so. The report should appear in Notepad after the reboot.
• Close OTM.

Now navigate to the C:\_OTM\MovedFiles folder ( assuming your Windows drive is C). This is where your log will be
saved in the form of Date and Time mmddyyyy_hhmmss.log. Just look for the most recent .log file. Attach
this log file to your next message.

Now please download Junkware Removal Tool to your desktop.

• Shut down your protection software now to avoid potential conflicts.
• Run the tool by double-clicking it. If you are using Windows Vista or Seven, right-mouse click it and select Run as Administrator.
• The tool will open and start scanning your system.
• Note: That JRT may reset your home page to a google default so you will need to restore your home page setting if this happens.
• Please be patient as this can take a while to complete depending on your system's specifications.
• On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
• Attach JRT.txt to your next message.

Try to do the below in Normal Boot Mode if possible.

Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista or Win7, don't double click, use right click and select Run As Administrator).


Then attach the below logs:

• the C:\_OTM\MovedFiles log
• the JRT.TXTlog
• C:\MGlogs.zip

Make sure you tell me how things are working now!
