Happening right now in Opera | Opera Security
I have install ZoneAlarm Free and on the manual option it appear a lot of ZoneAlarm dialogues asking for permission to comunicate with explorer.exe from Opera.
Is it normal or a anomally?
In normal cases Opera shouldn't interact with EXPLORER.EXE and why does it open various processes in the same tree? In the past this indicates that malware were been injected in the main process making it possible for a trojan to comunicate to the server.
Opera has a different processes for each tab, extension, etc, just like Chrome. They both do this so that a problem with a tab or extension that causes it to crash doesn't crash the whole browser.
