Trojan.Gapz is a Trojan that opens a back door on the infected computer. Trojan.Gapz may also download and install additional PC threats. Once executed, Trojan.Gapz inserts itself into the legitimate process 'explorer.exe'. Trojan.Gapz then ends the original process. Then Trojan.Gapz deletes itself from the file system. Trojan.Gapz uses bootkit functionality to affect Master boot and Volume boot records so that it can run automatically every time you start Windows. Trojan.Gapz uses the affected boot record to load a malicious driver code, which allows additional components to be downloaded and code to be inserted into user processes. Trojan.Gapz may connect to certain remote locations: Trojan.Gapz attempts to elevate its execution privileges by exploiting one of the following vulnerabilities:

Microsoft Windows User Access Control (UAC) Bypass Local Privilege Escalation Vulnerability (CVE-2010-4398)
