"Virus found" by macupdate . com. Is it a valid Apple site?
In Safari, I typed in a new (to me) website address. Immediately after hitting 'enter' a window popped up saying:
http : / / macupdate . com - apple . menu (I put the spaces in so it wouldn't become a hot-link)
VIRUS FOUND
The last website you visited has infected your Mac with a virus.
Press OK to begin the repair process.
There is no other option than to press OK but being a sceptic I force quit Safari and turned off the Mac Pro. Later when I turned it back on and tried to open Safari the same window popped up again. Is this a valid Apple site or is a hacker fishing? If it is a hacker, how do I get past the "press OK" window safely?
Thanks for any help.
Mac Pro, Mac OS X (10.7.5)
