Hi, I see my screen popping on for no reason staying on for 5 minuets or so then going back to sleep. Is this normal? I don't recall it doing this before but I have added an old p.c. to my network and got an iPad. Don't know if ether of those things have any relevance but like i said, I don't remember it happening before. From what I understand, to get spyware or malware on the computer I need to instal it. But I could be wrong. I have an iMac running 10.6.4. Thanks for any help.
