Opera.exe is an alternative web browser. More information can be found here. I personally prefer FireFox.
The most full-featured Internet power tool on the market, Opera includes pop-up blocking, tabbed browsing,
integrated searches, and advanced functions like Opera's groundbreaking E-mail program, RSS
Newsfeeds and IRC chat. And because we know that our users have different needs, you can
customize the look and content of your Opera browser with a few clicks of the mouse.
Every attempt has been made to ensure the information about Opera.exe is accurate but alot of malware applications try to pose as valid applications. If it is something other than what was posted above please leave some feedback in the forum.
