I'm pretty sure my Mac is infected, as some strange things have been going on. 1) My "view options" were originally set to snap to grid. Now they aren't; I have not changed the settings what so ever. 2) My password (!) changed. I tried to install something the other day using my current password, and the installer showed the "wrong password" message. I did NOT change the password. 3) I previously had flash INSTALLED, yet I load up Firefox today, and what happens? I get "Install Missing Plugins to view content on this page". I did not uninstall flash (I would not; YouTube surfer). Is it a Virus or just my 3 year old Mac acting up. (I use it A LOT) Also, I'm currently triple scanning with ClamXav. (which is a neat piece of software, BTW!) Thanks for the replies.
