Chances are, from what I can pinpoint, the adware virus did come from the Shockwave site. Or perhaps an Ad popped up while ye' were at dinner that gave ye' the virus. I'd let yer anti-virus system do what it was programmed to do- remove the virus completely. I'd perform another scan and if anythin' malicious pops up, remove it immediately before it gets worse and yer computer becomes more infected. If push comes to shove, I'd show yer parents also and see what they can make out of it. It's a stretch but if this adware virus is worse than ye' realized, ye' might need to get yer computer system checked out by someone with experience towards these kinds of unfortunate situations.
