Welcome to TechSpot, united. I'll help with the malware.
I'll help you reset the Cookies to prevent them in the future. but the 2nd SAS scan found Trojans so we need to work on them first.

The most important thing you can do first is update AVG from v8 to v9.xx.

Then Please download ComboFix HERE:

• With ComboFix, at the download window, please rename it to Combo-Fix(.exe) before downloading it.
  
  Important! Save the renamed download to your desktop.
  
• Please disable all security programs, such as antiviruses, antispywares, and firewalls.
  
• Double click on the setup file on the desktop to run
• If prompted to download and install the Recovery Console, please do so.
  (Please note: If the Microsoft Windows Recovery Console is already installed, ComboFix will continue it's malware removal procedures.)
• If prompted to update, please allow.
• Click on Yes, to continue scanning for malware.
• When finished, it will produce a log.Please include the C:\ComboFix.txt in your next reply.

Notes:

• 
  1.Do not mouse-click Combofix's window while it is running. That may cause it to stall.
  2. ComboFix may reset a number of Internet Explorer's settings.
  3. Combofix prevents autorun of ALL CD, floppy and USB devices to assist with malware removal & increase security.
  4. CF disconnects your machine from the internet. The connection is automatically restored before CF completes its run.

.
Follow that with Run Eset NOD32 Online AntiVirus Scanner HERE

• Tick the box next to YES, I accept the Terms of Use.
• Click Start
• When asked, allow the Active X control to install
• Disable your current Antivirus software. You can usually do this with its Notification Tray icon near the clock.
• Click Start
• Make sure that the option "Remove found threats" is Unchecked, and the option "Scan unwanted applications" is checked
• Click Scan
• Wait for the scan to finish
• Re-enable your Antivirus software.
• A logfile is created and located at C:\Program Files\EsetOnlineScanner\log.txt. Please include this on your post.

The Eset scan will show us what else has gotten past outdated programs.

Please attach the Combofix report and Eset log to your next reply.

Please do not use any other cleaning programs while I am working with you. If you have a Registry Cleaner, please disable it and do not make any registry changes.

Your main problem is that the system is full of torrent programs and data:
P2P or 'file sharing' Warning:
Note: Even if you are using a "safe" P2P program, it is only the program that is safe. I suggest that you uninstall [all torrent related programs[/b] for the following reasons:

• As long as you are using file sharing networks and programs which are from sources that are not documented, you cannot verity that a download is legitimate.
• Malware writers use these program to include malicious content.
• Fie sharing is usually unmonitored and there is a danger that your private files might be accessed.
• The 'sharing' also includes malware that the shared system has on it.
• Files that are illegal can be spread through file sharing.

Please read the information on P2P Warning to help you better understand these dangers.

I have started you off below. It's up to you.

• 
  [1]. Close any open browsers.
  [2]. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

I think the added problems are 'user caused'. Here's some comparison for you:

And I set these up for removal twice: But it appears you are continuing to use them in spite of my P2P Warning

You also has an entry:2010-04-07 08:01 . 2009-05-01 21:11:- c:\program files\folder
What is this?

As long as you continue to use P2P programs, you are going to get malware.

Please run Combofix again. You can delete the previous exe files for Combofix on the desktop before rerunning. Leave new Report.

The last data shows:

In between the first Combofix and this one, you downloaded and installed HitmanPro.

Why did you do that?

Some days I have to stop and ask myself why I do this! You changed the system when you did that.

Yes, a few. Based on what I read and the cleaning programs I run. Others may think differently. The publisher's description is:

Part is personal preference, wanting to maintain control over my system. Hitman is also different in the versions. One main objection is the use of multiple programs that are free on the internet. Depending on the program, it should prevent and/or remove. While the scans with Hitman are free, removal of the malware can only be done within the 30 trial.

Hitman Pro (version 1 and 2) automatically downloads, installs and runs third party anti-spyware and anti-adware programs that are freely available on the Internet:

Hitman Pro 3 uses a white list that includes Windows system files and other (safe) files that are present on most PCs. Hitman Pro 3 also requires a license key to remove malware found on a users computer, however it does offer a free 30-day trial.

The new version of Hitman Pro, version 3, uses:

None of these programs- alone or together have the power of a program like Combofix- or other 'intensive' programs. While Hitman may resolve one problem, that does not mean all of the malware has been removed.

Most of the logs I see have multiple malware infections. Some, like the DNS Changer malware, will require a DNS flush and a router reset. If that isn't done, the resolution to the problem is only temporary.

Remove my cleaning tools:

Uninstall ComboFix and all Backups of the files it deleted

• Click START> then RUN

Note: If you receive a warning from your firewall or other security programs regarding OTC attempting to contact the internet, please allow it to do so.

You should now set a new Restore Point and remove the old restore points to prevent infection from any previous Restore Points.
