Hello and welcome to Bleeping Computer.

Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

Double Click zztoy.exe to install the application.
* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

Let's submit the file "C:\WINDOWS\system32\Drivers\agp440.sys" to Virus Total so that it will scan it with multiple scanners to see if it is a False Positive.

To submit a file to Virus Total:

-Go to Virus Total
-Click the Browse button and then browse to the file's location. Once there, click the file and then press open.
-Then click Send File
-Please wait for the scanner to finish processing the file.
-Once done, please copy and paste the results on this page into your next post.

Ok so:

10/26/2009 5:39:04 PM Real-time file system protection file C:\WINDOWS\system32\Drivers\agp440.sys a variant of Win32/Kryptik.ABX trojan unable to clean TOM\Home Event occurred during an attempt to access the file by the application: C:\Program Files\Malwarebytes' Anti-Malware\mbam.exe.


Is a False Positive.

And then you can get rid of the other by following these instructions:

Create a new Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
Go to Start > Programs > Accessories > System Tools and click "System Restore".
Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
Then use Disk Cleanup to remove all but the most recently created Restore Point.
Go to Start > Run and type: Cleanmgr
Click "Ok"
Disk Cleanup will scan your files for several minutes, then open.
Click the "More Options" Tab.
Click the "Clean up" button under System Restore.
Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
Click Yes, then click Ok.
Click Yes again when prompted with "Are you sure you want to perform these actions?"
Disk Cleanup will remove the files and close automatically.



Are you experiencing any other symptoms besides those?
