I recently got a Macbook. I love it so far, I've had it for less than a week. I had been using it at my mom's (she uses on of those Timemachine things. They double as a wireless router right?) Anyways that was working great. Now I'm at my dad's where the computers (PCs) have had histories of viruses, worms, and other bad stuff; this is mainly cause my dad and step family are idiots about downloads and aren't very responsible. Anyways, I was just browsing the internet today - no weird sites that would be fairly dangerous - and a message popped up saying that I could be infected! I was feeling safe just the other day learning that Macs are very safe from computer viruses and stuff. A windows message popped up to notify me (which is really strange because I had only installed Windows office on this Macbook). But I'm thinking that its a fake message and instead some sort of trojan horse. Could it have come through the wireless network to reach this Mac? I dunno what happened, but I'm scared because this Mac is new and I would really like it to not screw up. But if it does, I got this Mac through my university, so I have support and a warranty, so I could get this replaced if it got really bad right?
