Adobe has patched a critical bug in its popular Macromedia Flash Player. Exploitation of the flaw could leave your computer completely compromised via memory corruption, according to security researcher Fortinet.

When you visit a website that contains a Flash movie (written as an .swf file), Flash Player will automatically load on your PC and play the file.

All you have to do is visit a booby-trapped site. Once there, the file would play with no additional click from you. Versions 8.0.24 and earlier are at risk, PC Advisor is told. Get Adobe’s updated release, version 9.0.16, here.
