When closing down Safari last night a pop warning appeared showing what looked like a hard drive picture and a warning message saying that I may have been infected with a virus and up to 7 Trojans have been identified. It looked scary and even had a Safari symbol in the pop as it was asking me to run a program but it didn't seem to be coming from my MAC. I did not install anything and shutdown the MAC in a panic. Once restarted everything was fine and has been all day. In my download history I saw this pop-up or download. I clicked on it to get info and its to www.spywarefastscannerv9.com. I am not sure if this is just a wild hit to get me to buy some spyware software (which I thought I don't need with the MAC) or some sort of malicious malware. Internet search reveals some unpleasant feedback that its malware. I'm panicking. I never installed anything but this stupid pop-up download is now sitting in my download file with all my other downloads. Should I trash it and move on? This was the first pop-up since I bought the new MAC 5 months ago. I left the PC world because of this stuff. Someone with some MAC skills please tell me its all good. Any advice?
