HTASploit.winmain

Overview

HTASploit.winmain starts up the legitimate mshta.exe process from Microsoft, making it possible to run VBScript in ANY web page which is a major security risk. HTASploit.winmain leaves an open door to install and run any software on an infected machine, from a web site that the user visit. This has probably been used to force adware onto users' systems.
