My brother-in-law's Dell Inspiron 530, Windows Vista, IE 9) is infected with the Alureon rootkit. I have tried MSSE, Windows Defender, Malwarebytes, and Kaspersky and none of them has worked. The bug has Internet access and antivirus updates blocked, so I downloaded MS Support Emergency Response Tool, Avast! Antirootkit, and a couple of others here at home and put them on a CD. I'll try those tomorrow when I go over. Problem with the CD: his CD/DVD drive is just about worn out and I couldn't install a game sis Sherrie wanted on there a few days ago, before the bug hit. If I have to remove it manually, I'm not sure where this one takes up residence in the Registry? Any help here greatly appreciated!
