you actually did NOT state that in any of your previous posts, and you have no proof that there isnt one that will do that (i have not shown proof that there is one, but it is difficult to find a list of viruses that state if they install them self or not). To get rid of spyware is a little trickier than that, you have to delete out the cookies to get rid of those and adware actually installs itself on to the system, a browser reset wont fix that.
I am not a member of any blackhat hacker communities so i would not be able to link you to any malicious software, and i would not want to be held responsible for any damage to your computer or others. I will however encourage you to go out on the internet and go hunt one down yourself so you can see for yourself that they are in fact out there.
my proof that there is no viruses for mac is: when apple first came out with leopard, they did basically a contest that if someone could create a virus for there operating system they would pay them 25,000$ and the offer still stands today....
there were plenty of viruses for mac os 9 but not for leopard // snow leopard...
