I would advice people this to avoid any type of hacks.
Keep in mind a good hacker will be able to get on your computer, but these guys aren't usually pestering mmo players.
1: Use firefox
2: Install no script and add block, give permission to sites.
3 Private browsing so it deletes your cach
4: Put flash player control on block everything from each site.
5: Virus scanner , personally I like Eset
6: Spybot
Most of all don't log in or be online while having a site with flash adds up, just avoid this.
I would even recommend you not going to ZAM.
Don't have a browser game up while playing ARR either.
The log in device SE has should help a lot as well.
Some sites don't look malicious at first but they can be even when the owner has no idea about it.
This will reduce your chance of being hacked
As for the PS3 I've no idea how they managed that.
