First detected spyware attacking Mac OS X Picture 1 F-Secure has tested and confirmed that iAdware is fully capable of opening a new Safari browser window every time a user uses the web browser.
" We will not disclose iAdware specifications ," F-Secure said. " What iAdware can do is not the Mac OS X operating system security bug. However, the danger is that the software installs a System Library without warning users ."
The software can be installed without the need for administrator access. " The administrator can install this software on every user's account ."
