Phishing and Malware

Hey there. I made a couple of threads already regarding a dodgy email I received and it's legitimacy, but this is about phishing and malware.

Received an email yesterday asking for feedback with my recent iPod purchase. I purchased a new Nano about a month ago. I opened the link on my email on both my Windows machine first, then after questioning the legitimacy on this forum, I then tried it on my iPad. I was logged into my Apple account on my Windows machine as I was on the discussions page, querying the email. I went through the questions seeing if it would ask for my login details - in which case I'd know it was fake - but it didn't. I didn't finish the survey, it was going on too long.

Anyway, I asked Apple about the email and had a reply today saying that it wasn't from them. Now I'm a bit concerned about phishing and malware on both my Windows machine and my iPad. I've ran an AVG scan on my laptop and it came back clean, but I dunno what I can do with my iPad, apart from a restore. What can I do to check my laptop isn't infected, nor is my iPad?

If you want to see the link the 'survey' took me to, I can post it. It was through a website called Advanis.

Thanks.
