MBR Alureon
« on: March 08, 2012, 02:53:41 PM »
Yesterday I got MBR Alureon on my computer. After trying various things to remove it I gave up and booted up on my recovery disc and reformatted and reinstalled from from an image I had on my external drive.  The external drive was plugged in the computer when I discovered I had MBR Alureon.  One of the effects of Alureon was that all of my directories on my harddrive and on my external drive showed to be empty.  I unplugged the external drive, plugged into my son's laptop and it still showed empty.  Panic!  But then I discovered they were really there but I just couldn't see them.

The computer reformatted and restored the image and now all seems to be well and oddly even the external drive is showing all the files now.  I am a bit concerned.  I don't know if the external drive had some of the infection and could reinfect me when I used it to reinstall the backup image.  Also, I don't know if the MBR is clean or repaired when you reformat and reinstall.

Also, I don't understand anything about MBR. I do have a partition drive and Windows 7, 64 bit.

How do I know this thing is really gone? I did an avast full system scan which was clean. I have no pop ups or anything suspicious at this point.

I did not log into any websites while infected but I am still concerned that sensitive info. such as passwords were compromised but I am afraid to log in to sites or change passwords if I might still be infected.

Can someone tell me how to know for certain I am ok now or if you think I am? I don't understand what was happening with my external drive. Why did it not show directories when plugged into my son's laptop unless something is infected on it too?

Soon as I feel my computer is clean I will create a new backup but if I am just taking this infection with me that is a waste of time.

I just downloaded and ran a scan from aswMBR.  HEre is the log.

Follow this guide and also attach Malwarebytes and OTL logs
http://forum.avast.com/index.php?topic=53253.0


Then one of the malware removers will check it when they arrive
Chief Wiggum: Uh, no, you got the wrong number. This is 9-1…2.
