Her PC stopped working reliably. I tried to run Malwarebytes before and after running Chameleon in safe mode. MWB indicated it was Siredef.c rootkit and when I tried to have it Quarantined it froze. I read to try Kapersky tdss Kliller (in safe mode) and it comes up with nothing. I'm in a place of stuckness. I don't really want to have to wipe the drive and start from scratch. Your help would be appreciated, Thank You.
