We all know that a true malicious site is one that contains trojans or virii infecting its users computers but i was curious to know if, like me, being a webmaster you actually have a different definition of what a malicious site is in terms of what they do?

For example, lately im noticing a LOT more site doing an auto redirect to spyware cleaning programs that appear to try and 'scan' the PCs hard drive.

Likewise, im seeing more and more sites on the non-adult side of things using iframes to play audio and movie trailers, i guess because the site owner gets paid a nice chunk of change every time the ad plays in full or something?

So what about you folks, do you think of a malicious site differently to just a site that installs spyware, trojans and viruses?
