i want to stop ie: writing EXE/CAB/LNK ... files, calling MSHTA.EXE to parse remote web pages, accessing files outside "favorites" and cache("content.ie5"). i want to stop WSCRIPT.EXE from parsing files inside TEMP and cache. i want to stop the system running executable files located in TEMP and cache. afaik, i can stop ie 0day exploits by doing these things. so, i made this: http://umbrella.name/winblox/ of course, free. and you can define your own rules easily(assuming you guys know a bit about regular expression). it's totally a new idea(afaik). so, not for operational uses.
