and part with your money.
Currently there are NO viruses out there that attack OS X, none.
What you came up against was an attempt to convince you that your machine was infected. The perpetrators do a good job of making it appear as though there is a problem, and always offer to fix those problems, usually for a fee.
This type of scam is directed mainly at Windows users and enough people fall for the scam to make the whole thing a worthwhile scheme for the perps.
It is apparently quite easy to convince a Windows user that they have caught something.
Hopefully you did not part with any money for the "cure"
Symantec (Norton) has ceased production of an AV suite for the Mac, hmm, I wonder why, but if you feel that you must have something, take a look at ClamXAV. Google for the Mac version. Its free. There is another free Mac one but the name escapes me.
Bottom line: Your machine is NOT infected with any of the problems that the advertisement claimed.
I received a battery of messages indicating I had several viruses attacking me. It was a large pop-up page with the Safari icon. It looked (looks) legitimate. I opted for the cure and it downloaded about 4 "things" to handle the problem. When trying to open them, they said they were designed for Windows. I use a Mac OS 10.5.8 (Leopard).
I tried to load my old Norton Systemworks but it won't work with my Intel chip.
My Mac seems to be working OK now but the message appeared twice.
Think I should get a new copy of Norton and install?
