I have a 27" iMac running 3.4GHz Core i7 with 8GB memory and the latest version of OSX 10.7. Some Internet web pages (CNet, for example) have videos that will not play on this computer. I get a message that I have no "Flash" player. True. Question: Is this Adobe Flash Player safe (virus, etc.) on my iMac? Any other problems with it . . Conflicts ? ? ? Thanks for your help.
