I was doing a full scan with MBAM and it found one thing. I thought to myself I hadn't run Avast for a few, so I did a thorough scan with that. It found Win32:Alureon-BV [Rtk]. I sent it into quarantine and let it finish the scan. It was the only thing it found. So, I did another scan with MBAM and it found nothing. Well, I have no idea what this thing is that Avast found, so I came here for some help. Before I scanned nothing out of the ordinary had happened, so I didn't think Avast would find anything. Please help if at all possible. Thanks in advance.

Hi, this may be a variant of the Trojan:Win32/Alureon.gen family. hence an info staeling Rootkit. Possibly caontaining this Rootkit. So best we check.
Also what was the one thing MBAM found?

We Need to check for Rootkits with RootRepeal[*]Extract RootRepeal.exe from the archive (If you did not use the "Direct Download" mirror).
[*]Open Posted Image on your desktop.
[*]Click the Posted Image tab.
[*]Click the Posted Image button.
[*]Check all seven boxes: Posted Image
[*]Push Ok
[*]Check the box for your main system drive (Usually C:), and press Ok.
[*]Allow RootRepeal to run a scan of your system. This may take some time.
[*]Once the scan completes, push the Posted Image button. Save the log to your desktop, using a distinctive name, such as RootRepeal.txt. Include this report in your next reply, please.

EDIT: Not sure what you want to know. Booted up just fine, everything loaded up like it was supposed to. One thing though...when I booted up, I got a pop up saying "Windows has blocked some startup programs". I checked to see what it was and it is MBAM. Dunno if that's anything to be worried about, but that is what happened.

Well it looks good, i suspect that would be Your Antivirus or the firewall blocking an intrusive application as it some times should. Uninstall MBAM. and see if it goes away.

Yes looks like you have.
Reinstall and run MBAm.. May as well be safe while we are here.

OK, you are good to go,unless you have something else.

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 backed up, renamed and 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, then 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.

I think something might be hiding on my laptop. When I rebooted after the MBAM scan, windows had blocked it at startup again. Maybe I'm just being paranoid, but it just doesn't seem it should be this easy...

Quite possibly. We should post another log then to be safe.
You will need to run HJT/DDS.
Please follow this guide.Preparation Guide For Use Before Using Hijackthis. Then go here HijackThis Logs and Virus/Trojan/Spyware/Malware Removal ,click New Topic,give it a relevant Title and post that complete log.

Let me know if it went OK.
