At the time of first release in 2004 it introduced innovative rootkit detection techniques and quickly gained popularity for its effectiveness. It was incorporated into a few antivirus tools including Avast! antivirus[6] and SDFix.[7]

For several months in 2006 and 2007, the tool's website was the target of heavy DDoS attacks attempting to block its downloads.[8]
