I've had my macbook for probably a year and a half now and have never seen this before but it's creeping me out. Today, suddenly, my finder has started quitting whenever I go to the "applications" tab. Every other part of the finder works but the applications refuse to open. It's worrying me because I think it could be one of those few mac viruses. I'm running a virus scan at the moment to see. Also on the possible virus front. I had cleaned my HDD the other day and gotten it to 58 gigs left of free space. A few days later it came up as 78 free though which confused me. I had downloaded a program called macaroni to run some stuff on my computer and I'm worried it might have done something to it, does anyone know if my hunch is right? Also, I deleted the preferences already and restarted, as well as straight re-starts several times but no luck. Does anyone have an ideas of what to do? I'm running on Snow Leopard, if that helps.
