good morning, my mom's mac seems to be infected with some kind of adware. she gets these random popups for viagra (the viagra ad is always the same) and also pornographic material. i had her install and run a couple of free antivirus program (ClamXav and iAntivirus) and neither of those programs found anything. i've had her "reset" safari and restart the computer, but that didn't make it go away. she also deleted her microsoft messenger application. a red exclamation mark is now appearing up at the top right of her screen - next to the the time machine icon. when she clicks it, a window appears underneath it and gives different options: scan now clean up control center system info settings about register when she does the "scan now" option, the red exclamation mark blinks and it says virus found: spyware, safari webpage backdoor, safari sync, trojanfpurpdatepf does anyone have any idea what is going on? i've been using macs for many years and have never seen anything like this. she just uses the computer for email. if anyone has any suggestions it would be greatly appreciated. thank you.
