For the past couple of weeks my computer has started freezing randomly (sometimes during bootup). I have used malawarebytes and found problems, some of which did not delete. Following are the logs from HijackThis and Malawarebytes. Help will be greatly appreciated.

Ok....lets check.

Ok.Lets download ComboFix.exe. This will give me a better view to the files running and also hidden on your computer and also those in the registry..Please visit this webpage for downloading and instructions for running the tool:

Go here ======> A guide and tutorial on using ComboFix <====== Go here

Please ensure you read this guide carefully and install the Recovery Console first.This applies to XP Pro and XP Home users only.If you have SP3 installed you will need to use SP2.Do not use for Vista.

The Windows Recovery Console will allow you to boot up into a special recovery (repair) mode. This allows us to more easily help you should your computer have a problem after an attempted removal of malware. It is a simple procedure that will only take a few moments of your time.

Once installed, you should get a prompt that says:

The Recovery Console was successfully installed.

Please continue as follows:

(1) Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
(2) Click Yes to allow ComboFix to continue scanning for malware.

When the tool is finished, it will produce a report for you.

Please include the following reports for further review, and so we may continue cleansing the system:

C:\ComboFix.txt
New HijackThis log.

Caution: Never run and remove files with Combofix unless supervised by a qualified security analyst who is experienced in the use of Combofix. Mal use can cause serious computer problems

NOTE: Combofix prevents autorun of all CDs, floppies and USB devices to assist with malware removal & increase security. If this is an issue or makes it difficult for you - please let me know.
