Malware's bytes false positive?

I got a reg key called windows/symstem/explorer/noactivedesktop changes but Malware’s bytes thinks its a hijacker? So I’m guessing this is fake because this reg key came with my copy of vista(64bit) So is this a fake or is it real?Plus if I try to remove my computer just shuts off

try sending it to www.virustotal.com but this should be in the MBAM forums though

Also i had a false positive because i had a Dumper of File for my customer for my cpu. So they say its a Trojan:FakeAlert they also did said the same to me. Its to ignore ;D So if you think you trust it and its really that true you said. Do what they will say. Add it to ignore. ;D
