Quality stuff. Apparently Symantec and ZoneAlarm's antivirus software (powered by Mcafee) can also remove the rootkit, thought I've not tested this (and I don't want to!)
In other news, there's lawsuits in Italy, America and the UK, amongst other countries, all sueing Sony on this. "Nibbled to death by the ducks" was one phrase I rather appropriately read on nanae earlier today. (Nanae is, for those who don't know, a newsgroup which discusses the fight against spam, so unrelated but still a somewhat interesting place for those kind of discussions).
