DeepFreeze etc bypass ? Lots of claims from HT about their software ! Sounds like a rootkit to me, but even if it is, how would it evade DeepFreeze, Returnil, ShadowDefender etc ? Obviously they would have to get their stuff installed by someone allowing .EXE's, .SYS's etc etc to run. So let's presume they did, now what ? "Most" = not all then I expect a good ARK would find it ?
