We’ve noticed this pop-up message on sites we regularly visit, lately. If you should see this pop-up:
… terminate your browser and not the pop-up itself. This pop-up will install malware on your computer if you allow it to run.
If you should see any pop-up on sites you visit pertaining to needing updates (Adobe Flash, Java, Windows Media Player, etc.), do not install them from that site. This is not the same as the Adobe/Java update icon that may occasionally display in the lower right of your desktop. These are legitimate updates and you may apply them. However, be sure to uncheck any additional software installation offers like Google Chrome or Ask Toolbar – Java updates have been offering these options.
