Hi all, I recently used this forum to clean 2 infections (DNSChanger and Clickr.fr). I'm curious as to what damage might have been done by these things? I don't know how long the DNS Changer was on my system. Do I need to change passwords to the various sites I visit (MySpace, etc?)? Or from Thunderbird? I don't think the Clicker even ran because AVG caught it. Secondly, would either of these have been able to install themselves if I wasn't running in Administrator mode? Thanks in advance skills
