I've just started getting this wretched Aurora pop thing too as I see many others have. I have the Microsoft Antispyware Beta thing and Adaware and they pick it up and tell me that they have cleaned it out but it keeps coming back and judging by the information on here it seems that it's as much good as a chocolate fireguard. I've also had a message about someone trying to install a new dial up number or something.
I'm not that techy and some of the advice on here looks a bit scarey. I'm OK following instructions but if it goes pear shaped I won't know what to do!
I've installed the Hijackthis on the desktop. Can you please hold my hand and tell me what to do next. Thanks.
