Adobe Systems Inc. said Tuesday that it was investigating an attack using Adobe Flash files to hijack end users' clipboards.
The attack, which was made public via a number of discussion boards, exploits Adobe Flash files served by a number of popular websites. When a victim's clipboard is hijacked, the infected file replaces clipboard information with a link to a website that sells a fake antimalware program. The only way to stop the hijacking is to reboot the computer.
The attack affects Firefox and Internet Explorer users running Apple OS X and Windows. The earliest reports of clipboard hijackings were posted on discussion boards last month.

"Researchers are investigating potential solutions to this issue and will update customers as soon as we have more information to provide," according to a
