Was just sent an audio clip to download from a Fileserve page. Now I know many use them, but it popped up so many pages that I know if I'd been on windows I'd probably have been in trouble, or at least got a few trojans come up on a scan afterwards. Now the only way of getting rid of some of these was to click their 'OK' box as they don't have the Mac traffic lights to close the box. Point being, what was I actually saying 'OK' to, I doubt it was just to close the box? Can it plant anything hidden in the Mac without a password? I don't really want to put scanners, and AV on the MBP, it defeats the object of losing Windows .... I look on the ClamXav forums and there are thousands of posts about viruses, trojans, spyware, email viruses, trojans in Flash and posing as pdf files etc. Are these really all Mac users??? I thought they can't get viruses without immense stupidity and putting in your password for stuff you don't know about. They're not all doing that, surely!! If I get a trojan on the mac what can it do? If I download ClamXav will it run all the time, is it necessary, do I really want it? What will it find and is it going to run in background and hog resources like they do on XP?
