There are many apps around specifically aimed and sold as "undetecting software" ,trojans and virus that would otherwise be "detected" will be made "undetected" to mention a few of these types of software, (morphine ,antidote ,mr undetectable) Most of these undetecting programes don't come for free and are soon detected because of thier widespread use ,These apps have no legitimate use there only intended use is for protecting "malware apps" However for many months which is longer than most trojans themselves stay undetected i and many others i presume have used legitimate "software protcetion" or "anti crack software" to protect "malware" and successfully defeated all antivirus tested including kav, nod32, mcafee,norton, in both real time! and scan time! my questions are how widespread is this use of "software protection" tools used to protect malware? why has kav not caught this method? being a big fan of kav myself and user of kav for many years im a little disopointed in kav being defeted so easy, as this method requires no knowledge simply just point and click undetection no knowledge of assembley or xor encryption needed. Since "anti crack software" is only intended for legitimate use, i have not seen any of theses software types sold or advatised to protect "malware" there sole intention is for protecting legitimate programes from being cracked, will this make detection harder as this software is legitimate? will gennuine programes protected with this method of software protection give false positives?
