Hi, I'm a 10.4.11 user. As well as using what is obviously now an ancient system, I've also been under a bit of a rock lately and only just learnt about the whole flashback.g 'certificate' thing going around. I actually did encounter it a little while ago (my Java is turned off, so I guess that explains why it didn't take advantage of that) but I couldn't recall whether I'd moronically hit 'continue' or not, so did some checks, as suggested here http://www.macworld.com/article/165...ous_strain_of_mac_flashback_trojan_horse.html: ls /Users/Shared/.*.so and defaults read ~/.MacOSX/environment came back with 'No such file or directory', and 'does not exist'. Seems fine, but I gather the bad guys may well have changed the locations of these files since that article was published - and I also recently learnt that only Snow Leopard + has in built anti-virus/is updated and protected by Apple. Is that true?? (I'll try and find links if anyone's sceptical...) On a final note, I also learnt here http://antivirus-software.findthebest.com/compare/134-141/2012-Kaspersky-Anti-Virus-vs-2012-ClamXav that ClamXav (which I just used to scan my system, after updating its definitions) only responds to viruses, not other malware threats (like Trojans, presumably). Which perhaps, is a little pointless - unless you're concerned about Windows viruses - since there are no Mac viruses, as they say. All in all, with an old OS, a useless (in the face of these kind of threats?) ClamXav, and it appears, no protection from Apple, I'm wondering if using Tiger is just asking for trouble now. Even with Java switched off. What do you reckon? And is anyone else using Tiger here, or am I the only one left...? Thanks to anyone who get back to me on this issue!
