This is a nasty piece of malware that craps out your system. You can’t boot up and a boot disc “blue screens” your system.
After connecting the drive via USB cable to my forensic machine, I threw the usual malware removal tools at it first. Malwarebytes, SUPERAntiSpyware, and yes, Microsoft Security Essentials. MSE was the only one to recognize the rootkit and at least give me an idea as to what ailed this system. It was the Trojan:DOS/Alureon.A, which is an Alert Level Severe!
Unfortunately MSE couldn’t remove it, so it was going to take a special tool to scrub this bad boy from the master boot record and Kaspersky came to the rescue with TDSSKiller.exe.
It very quickly found the rootkit and “Cured” it. I re-ran it just in case and I was good to go.
For more information, head on over to Kaspersky.
