real subscription sites should be safe. jennahaze.com clubcharlie.com (charlie laine) zerotolerence.com etc.. are all 100% safe. they are actual professional sites.
when you start getting into the free movie clip and picture sites, thats where u risk it. freeones.com, for instance, is a 100% safe site that falls into the general dangerous catagory. but the difference is, they are a legit company. they actually have a purpose, promoting stars, sites, and companies. but others make their bucks by throwing you in random sites. every 3rd link takes you to somewhere that had nothing to do with the pic you clicked on.
keep your firewall up, a decent antivirus, and a safe browser like firefox and you should be fine.
