Hello. I try to scan my Windows Vista computer with anti-spyware software every couple of months just to keep the machine clean. After not scanning the computer for a couple of months, I ran a scan first with AdAware which removed most of the standard tracking cookies and told me that there was one it couldn't remove. I then ran Malwarebytes and the log was as follows:

Malwarebytes' Anti-Malware 1.31

Registry Data Items Infected:

Files Infected:
C:\Program Files\Dell\Dell Mobile Broadband\systray.exe (Trojan.Agent) -> Delete on reboot.

I then reboted the computer (when prompted) and ran Malwarebytes again and it gave me the following results:

I have never had a Trojan before on any computer and the one that I ran this scan on is new (purchased in Sept. 08), so I would really like to make sure that it stays in good shape. Is my computer now clean and free of malicious bugs or is there something else I should do?

These seem to me like all relatively low-threat cookies and the nasty Trojan is gone. Is there anything else I should do or consequences of having had a bug I should be aware of?

Thanks for your help!

Yep,some harmless cookies. You look good to go.
Now you should 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.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.
